The Timer functional clock naming convention has changed from
gptX_fck => timerXfck, and so as the timer init function
in mach-omap2/timer.c.
OMAP4 clocktree also has changed accordingly.
AM33xx Clock Tree has been merged during rc3-4 timeframe,

for AM33xx as well (Change the gptX_fck => timerX_fck).

The new omap4 cpuidle implementation currently requires
ARCH_NEEDS_CPU_IDLE_COUPLED, which only works on SMP.
This patch makes it possible to build a non-SMP kernel
for that platform. This is not normally desired for
end-users but can be useful for testing.
Without this patch, building rand-0y2jSKT results in:
drivers/cpuidle/coupled.c: In function 'cpuidle_coupled_poke':
drivers/cpuidle/coupled.c:317:3: error: implicit declaration of function '__smp_call_function_single' [-Werror=implicit-function-declaration]
It's not clear if this patch is the best solution for
the problem at hand. I have made sure that we can now
build the kernel in all configurations, but that does
not mean it will actually work on an OMAP44xx.

The arm_pmu_type enumeration was initially introduced to identify
different PMU types in the system, the usual one being that on the CPU
(ARM_PMU_DEVICE_CPU). With the removal of the PMU reservation code and
the introduction of devicetree bindings for the CPU PMU, the enumeration
is no longer required.
This patch removes the enumeration and updates the various CPU PMU
platform devices so that they no longer pass an .id field referring
to identify the PMU type.

This reverts commit 58f0829b71.
Converstion to per-pwrdm per/post transition calls was a bit
premature. Only tracking MPU, PER & CORE in the idle path means we
lose the accounting for all the other powerdomains which may also
transition in idle. On OMAP3, due to autodeps, several powerdomains
transition along with MPU (e.g. DSS, USBHOST), and the accounting for
these was lost with this patch. Since the accounting includes the
context loss counters, drivers for devices in those power domains
would never notice context lost, so would likely hang after any
off-mode transitions.
This patch should be revisited when the upcoming clkdm/pwrmdm/voltdm
use-counting seires is merged since then we can properly do accounting
without relying on a call in the idle path.
In addition, the original patch had another bug because the PER
powerdomain accounting was not updated until after the GPIO resume
hook is called. Since gpio_resume_after_idle() checks the context
loss count (which is not yet updated) it would not properly restore
context, leaving the GPIO banks in an undefined state.

This is because recently merged OMAP5 platform shares the common files

the sleep code is meaningless.

1) The above commit introduced a common ->get_pendown_state() function
into the generic code, but that function was board-specific for the
OMAP3EVM and thus broke most other boards using this code.
2) The above commit was mis-merged introducing another bug which
prevents the ads7846 driver probe function to succeed.
The omap_ads7846_init() function frees the pendown GPIO in case there is
no ->get_pendown_state() function set by the caller (board specific
code), so it can be requested later by the ads7846 driver.
The above commit add a common ->get_pendown_state() function without
removing the gpio_free() call and thus once the ads7846 driver tries
to use the pendown GPIO, it crashes as the pendown GPIO has not been
requested.
3) The above commit introduces NO new functionality as
get_pendown_state() function is already implemented in a suitable way by
the ads7846 driver and the debounce time handling has already been
fixed by commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code).
This reverts commit 16aced80f6.

With a stable git workflow from the other maintainer we could have staged

The alternative is to hold it off until 3.7 but given that the code is

back hard in that direction.

"This looks scary at first glance, but what it is is:
- a rework of the sa11x0 DMA engine driver merged during the previous

- conversion of amba-pl08x.c to use these helper functions.
- addition of OMAP DMA engine driver (using these helper functions),
and conversion of some of the OMAP DMA users to use DMA engine.
Nothing in the helper functions is ARM specific, so I hope that other
implementations can consolidate some of their code by making use of
these helpers.
This has been sitting in linux-next most of the merge cycle, and has
been tested by several OMAP folk. I've tested it on sa11x0 platforms,
and given it my best shot on my broken platforms which have the
amba-pl08x controller.

OMAP4 idle driver uses CLOCK_EVT_NOTIFY_BROADCAST_[ENTER/EXIT]
for broadcast clock events. But _ENTER/_EXIT doesn't really open
broadcast clock events and to explicitly setup the broadcast device,
CLOCK_EVT_NOTIFY_BROADCAST_ON should be used.
Add the missing CLOCK_EVT_NOTIFY_BROADCAST_ON clockevent notifications.
This will setup the broadcast timer in either periodic/oneshot modes
correctly. Recent clockevent infrastructure change 77b0d60 {leave the
broadcast device in shutdown mode when not needed} exposed this bug
leading to boot hangs in oneshot mode. Prior to this, periodic broadcast
mode was also broken. This change fixes both the periodic/oneshot broadcast
modes.

With coupled idle states, a failure for any CPU to hit a low power
state must be coordinated such that all CPUs abort.
On OMAP4, when entering a coupled state, CPU0 has to wait for CPU1 to
enter its low power state before it can enter its low power state.
This is implemented by letting CPU0 wait for the CPU1 powerdomain to
hit off. However, there are conditions where CPU1 might abort/fail
and not hit off while CPU0 is waiting for it. For example, a CPU1
wakeup or a failed attempt to hit off due to hardware conditions.
To avoid the deadlock where CPU0 would continually wait for CPU1 to
hit off-mode, this patch adds a flag to signal when each CPU has come
out of its low-power state. CPU0 then checks whether CPU1 has hit off
*or* has already completed its attempt to hit off. If the latter,
CPU0 must abort its attempt to hit a low-power state so the coupled
state enter method can return.
In addition, cpuidle_coupled_parallel_barrier() is used to ensure the
clearing of the 'done' flag is synchronized on all CPUs.

OMAP4 CPUDILE driver is converted mainly based on notes from the
coupled cpuidle patch series.
The changes include :
- Register both CPUs and C-states to cpuidle driver.
- Set struct cpuidle_device.coupled_cpus
- Set struct cpuidle_device.safe_state to non coupled state.
- Set CPUIDLE_FLAG_COUPLED in struct cpuidle_state.flags for each
state that affects multiple cpus.
- Separate ->enter hooks for coupled & simple idle.
- CPU0 wait loop for CPU1 power transition.
- CPU1 wakeup mechanism for the idle exit.
- Enabling ARCH_NEEDS_CPU_IDLE_COUPLED for OMAP4.
Thanks to Kevin Hilman and Colin Cross on the suggestions/fixes
on the intermediate version of this patch.

For coupled cpuidle to work when both cpus are active, it needs a global timer
that can handle events for both cpus. This timer is used as the broadcast
clock-event when the per-cpu timer hardware stop in low power states.
Set the cpumask of clockevent_gpt to all cpus, set the rating correctly, and
set the irq to allow the clockevent core to determine the affinity of the
timer.

This adds support for three new SoC types:

group also made the older but similar platforms we call "orion5x",
"kirkwood", "mv78xx0" and "dove", we plan to move all of them into
the mach-mvebu directory in the future.
* socfpga is Altera's platform based on Cortex-A9 cores and a lot of
FPGA space. This is similar to the Xilinx zynq platform we already
support. The code is particularly clean, which is helped by the fact
that the hardware doesn't do much besides the parts that are
expected to get added in the FPGA.
* The OMAP subarchitecture gains support for the latest generation,

Pull arm-soc timer updates from Arnd Bergmann:
"This contains two branches dealing with timers, one for the picoxcell
platform that is now using DT with the platform-independent
dw_apb_timer driver. The other change is for the omap-specific
dmtimer driver."
* tag 'timer' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
clocksource: dw_apb_timer: Add common DTS glue for dw_apb_timer
ARM: OMAP2+: Simplify dmtimer clock aliases
ARM: OMAP2+: Move dmtimer clock set function to dmtimer driver
ARM: OMAP1: Fix dmtimer support
ARM: OMAP: Add flag to indicate if a timer needs a manual reset
ARM: OMAP: Remove timer function pointer for context loss counter
ARM: OMAP: Remove loses_context variable from timer platform data
ARM: OMAP2+: Fix external clock support for dmtimers
ARM: OMAP2+: HWMOD: Correct timer device attributes
ARM: OMAP: Add DMTIMER capability variable to represent timer features
ARM: OMAP2+: Add dmtimer platform function to reserve systimers
ARM: OMAP2+: Remove unused max number of timers definition
ARM: OMAP: Remove unnecessary clk structure
This branch contains two kinds of updates: Some platforms in the process
of getting converted to device tree based booting, and the platform
specific patches necessary for that are included here. Other platforms
are already converted, so we just need to update the actual device
tree source files and the binding documents to add support for new board
and new drivers.
In the future we will probably separate those into two branches, and
in the long run, the plan is to move the device tree source files out
of the kernel repository, but that has to wait until we have completed
a much larger portion of the binding documents.

Currently most ads7846 config definitions for OMAP3 series boards have
been moved to common-board-devices.c, and it is transparent for init.
And it's no very proper to do gpio_request based on get_pendown_state
since omap_ads7846_init knows everything about ads7846_config.
So it's more fit to request gpio according to the right gpio_pendown
and set debounce time conditionally. If we don't set proper debouce
time, there are flooded interrupt counters of ads7846 responding to
one time touch on screen, then the driver couldn't work very well.

Commit ac5b0ea3d (Merge tag 'omap-devel-f-for-3.6'...) had a merge
conflict that somehow got incorrecly resolved in a lossy way for
commit bed9d1bb (ARM: OMAP2+: hwmod: add omap_hwmod_get_main_clk() API).
Fix the issue by applying the missing pieces.
Reported-by: Santosh Shilimkar <santosh.shilimkar@ti.com>

Kevin discovered that commit c8d82ff68f
("ARM: OMAP2/3: hwmod data: Add 32k-sync timer data to hwmod
database") broke CORE idle on OMAP3. This prevents device low power
states.
The root cause is that the 32K sync timer IP block does not support
smart-idle mode[1], and so the hwmod code keeps the IP block in
no-idle mode while it is active. This in turn prevents the WKUP
clockdomain from transitioning to idle. There is a hardcoded sleep
dependency that prevents the CORE_L3 and CORE_CM clockdomains from
transitioning to idle when the WKUP clockdomain is active[2], so the
chip cannot enter any device low power states.
It turns out that there is no need to take the 32k sync timer out of
idle. The IP block itself probably does not have any native idle
handling at all, due to its simplicity. Furthermore, the PRCM will
never request target idle for this IP block while the kernel is
running, due to the sleep dependency that prevents the WKUP
clockdomain from idling while the CORE_L3 clockdomain is active. So
we can safely leave the 32k sync timer in target-force-idle mode, even
while we continue to access it.
This workaround is implemented by defining a new clockdomain flag,
CLKDM_ACTIVE_WITH_MPU, that indicates that the clockdomain is
guaranteed to be active whenever the MPU is inactive. If an IP
block's main functional clock exists inside this clockdomain, and the
IP block does not support smart-idle modes, then the hwmod code will
place the IP block into target force-idle mode even when enabled. The
WKUP clockdomains on OMAP3/4 are marked with this flag. (On OMAP2xxx,
no OCP header existed on the 32k sync timer.) Other clockdomains also
should be marked with this flag, but those changes are deferred until
a later merge window, to create a minimal fix.
Another theoretically clean fix for this problem would be to implement
PM runtime-based control for 32k sync timer accesses. These PM
runtime calls would need to located in a custom clocksource, since the
32k sync timer is currently used as an MMIO clocksource. But in
practice, there would be little benefit to doing so; and there would
be some cost, due to the addition of unnecessary lines of code and the
additional CPU overhead of the PM runtime and hwmod code - unnecessary
in this case.
Another possible fix would have been to modify the pm34xx.c code to
force the IP block idle before entering WFI. But this would not have
been an acceptable approach: we are trying to remove this type of
centralized IP block idle control from the PM code.

As per recent discussion on the linux-omap list, we are
moving in the direction where, we will have only architecture,
ARCH_OMAP2PLUS and all devices/platforms will be treated
as a SoC underneath.
So the first step in this direction is to adopt this change
for all new devices getting in, converting

Initially, we decided to make am33xx family of device to fall
under omap3 class (cpu_is_omap34xx() = true), since it carries
Cortex-A8 core. But while adding complete baseport support
(like, clock, power and hwmod) support, it is observed that,
we are creating more and more problems by treating am33xx device
as omap3 family, as nothing matches between them
(except cortex-A8 mpu).
So, after long discussion we have came to the conclusion that,
we should not consider am33xx device as omap3 family, instead
create separate class (SOC_AM33XX) under OMAP2PLUS.
This means, for am33xx device, cpu_is_omap34xx() will return false,
and only cpu_is_am33xx() will be true.

The OMAP4 usb_host_fs (OHCI) and AESS IP blocks require some special
programming for them to enter idle. Without this programming, they
will prevent the rest of the chip from entering full chip idle.
To implement the idle programming cleanly, this will take some
coordination between maintainers. This is likely to take some time,
so it is probably best to leave this for 3.6 or 3.7. So, in the
meantime, prevent these IP blocks from being registered.
Later, once the appropriate support is available, this patch can be
reverted.
This second version comments out the IP block data since Benoît didn't
like removing it.

The DMADISABLE bit is a semi-automatic bit present in sysconfig register
of some modules. When the DMA must perform read/write accesses, the
DMADISABLE bit is cleared by the hardware. But when the DMA must stop for power
management, software must set the DMADISABLE bit back to 1.
In cases where the ROMCODE/BOOTLOADER uses dma, the hardware clears the
DMADISABLE bit (but the romcode/bootloader might not set it back to 1).
In order for the kernel to start in a clean state, it is
necessary for the kernel to set DMADISABLE bit back to 1 (irrespective
of whether it's been set to 1 in romcode or bootloader).
During _reset of the (hwmod)device, the DMADISABLE bit is set so that it
does not prevent idling of the system. (NOTE: having DMADISABLE to 0,
prevents the system to idle)
DMADISABLE bit is present in usbotgss module of omap5.

But this results in adding new CONFIG_ARCH_OMAPXXX

This way no new ifdefs would be required in the future and also

The wake-up power domain is an alway-on power domain and so this power domain
does not have a power state status (PM_PWSTST_xxx) register that indicates the
current state. However, during the registering of the wake-up power domain the
state of the domain is queried by calling pwrdm_read_pwrst(). This actually
tries to read a register that does not exist and returns a value of 0 that
indicates that the current state is OFF. The OFF state count of the wake-up
power domain is then set to 1 and the current state to OFF. Both of which are
incorrect.
To fix this, if a power domain only supports the ON state, do not attempt to
read the power state status register and simply return ON as the current power
state.
This is based upon Tony's current linux-omap master branch.
Testing:
- Boot tested on OMAP4460 panda.
- Boot tested on OMAP3430 beagle and validated CORE RET still working (using

For OMAP3+ devices, the clock domains (CLKDMs) support one or more of the
following transition modes ...
NO_SLEEP (0x0) - A clock domain sleep transition is never initiated,
irrespective of the hardware conditions.
SW_SLEEP (0x1) - A software-forced sleep transition. The transition is initiated
when the associated hardware conditions are satisfied
SW_WKUP (0x2) - A software-forced clock domain wake-up transition is initiated,
irrespective of the hardware conditions.
HW_AUTO (0x3) - Hardware-controlled automatic sleep and wake-up transition is
initiated by the PRCM module when the associated hardware
conditions are satisfied.
For OMAP4 devices, SW_SLEEP is equivalent to HW_AUTO and NO_SLEEP is equivalent
to SW_WKUP. The only difference between HW_AUTO and SW_SLEEP for OMAP4 devices
is that the PRM_IRQSTATUS_MPU.TRANSITION_ST interrupt status is set in case of
SW_SLEEP transition, and not set in case of HW_AUTO transition.
For OMAP4 devices, all CLKDMs support HW_AUTO and therefore we can place the
CLKDMs in the HW_AUTO state instead of the SW_SLEEP mode. Hence, we do not
need to use the SW_SLEEP mode. With regard to NO_SLEEP and SW_WKUP it is
preferred to use SW_WKUP mode if the CLKDM supports it and so use this mode
instead of NO_SLEEP where possible.
For a software perspective the above 4 modes are represented by the following
flags to indicate what modes are supported by each of the CLKDMs.
CLKDM_CAN_DISABLE_AUTO --> NO_SLEEP
CLKDM_CAN_ENABLE_AUTO --> HW_AUTO
CLKDM_CAN_FORCE_SLEEP --> SW_SLEEP
CLKDM_CAN_FORCE_WAKEUP --> SW_WKUP
By eliminating the SW_SLEEP mode the the mapping of the flags for OMAP4 devices
can becomes ...
CLKDM_CAN_DISABLE_AUTO --> NO_SLEEP
CLKDM_CAN_ENABLE_AUTO --> HW_AUTO
CLKDM_CAN_FORCE_SLEEP --> HW_AUTO
CLKDM_CAN_FORCE_WAKEUP --> SW_WKUP

and interrupts from the PMIC are needed as wakeup sources.
Ensure this pin is mux'd as input and has wakeup enabled so PMIC
interupts (e.g. RTC) can be used as wakeup sources.

AM33XX clock implementation is different than any existing OMAP
family of devices. Although DPLL module is similar to OMAP4
device, but the usage is very much different than OMAP4.
AM33XX has different peripheral set and each module gets
integrated to the clock framework differently than OMAP
family of devices.
This patch adds full Clock tree data for AM33XX family
of devices and also integrates it into existing OMAP framework.

Merge tag 'omap-devel-d-for-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into fixes-non-critical
Some OMAP AM35xx fixes.
The powerdomain and clockdomain data for the AM35xx are finally fixed.
The AM35xx EMAC/MDIO Ethernet controller integration code has been
converted to use the OMAP device and hwmod framework. Also the UART4
and HSOTGUSB warnings have been fixed.
commit 164e0cbf60 (ARM: OMAP3/4: consolidate cpuidle Makefile) added
an OMAP-specific dependency from CPU_IDLE to CONFIG_PM. This causes
some randconfig warnings when CONFIG_PM has unmet dependencies:
warning: (ARCH_OMAP3 && ARCH_OMAP4) selects PM which has unmet direct dependencies (PM_SLEEP || PM_RUNTIME)
warning: (ARCH_OMAP3 && ARCH_OMAP4) selects PM which has unmet direct dependencies (PM_SLEEP || PM_RUNTIME)
warning: (ARCH_OMAP3 && ARCH_OMAP4) selects PM which has unmet direct dependencies (PM_SLEEP || PM_RUNTIME)
Fix this by making the dependency on CONFIG_PM_RUNTIME (which in turn
will enable CONFIG_PM.)

During kernel init, the AM3505/AM3517 UART4 cannot complete its softreset:
omap_hwmod: uart4: softreset failed (waited 10000 usec)
This also results in another warning later in the boot process:
omap_hwmod: uart4: enabled state can only be entered from initialized, idle, or disabled state
From empirical observation, the AM35xx UART4 IP block requires either
uart1_fck or uart2_fck to be enabled while UART4 resets. Otherwise
the reset will never complete. So this patch adds uart1_fck as an
optional clock for UART4 and adds the appropriate hwmod flag to cause
uart1_fck to be enabled during the reset process. (The choice of
uart1_fck over uart2_fck was arbitrary.)
Unfortunately this observation raises many questions. Is it necessary
for uart1_fck or uart2_fck to be controlled with uart4_fck for the
UART4 to work correctly? What exactly do the AM35xx UART4 clock
tree and the related PRCM idle management FSMs look like? If anyone
has the ability to answer these questions through empirical functional
testing, or hardware information from the AM35xx designers, it would
be greatly appreciated.

Partially fix the hwmod data for the AM35xx USB OTG hwmod. This
should resolve the following boot warning on AM35xx platforms:
omap_hwmod: am35x_otg_hs: cannot be enabled for reset (3)
While here, also fix the clkdev records, to avoid warnings about
duplicate clock aliases.
The hwmod is also connected to the wrong interconnect. It should be
connected to the IPSS, not the L4 CORE. But that is left for a future
fix, since it probably has a dependency on some hwmod core changes.

The problem is that currently none of the clocks are being registered for
OMAP4470 devices and so on boot-up no clocks can be found and the kernel panics.
This fix allows the kernel to boot without failure using a simple RAMDISK file
system on OMAP4470 blaze board.
Per feedback from Paul and Benoit the 4470 clock data is incomplete for new
modules such as the 2D graphics block that has been added to the 4470.
Therefore add a warning to indicate that the clock data is incomplete.

an oops on boot for all omap3xxx platforms that use usbhs_omap for
EHCI. The actual oops comes from faulty ehci-omap cleanup, but the
failure caused by the change is evidenced here:
[ 3.655059] ehci-omap ehci-omap.0: utmi_p1_gfclk failed error:-2
[ 3.661376] ehci-omap: probe of ehci-omap.0 failed with error -2
utmi_p1_gfclk is a clock that exists on OMAP4, but not OMAP3. In the
OMAP3 case, it is configured as a dummy clock. However, OMAP4 lists
the dev_id as NULL, but OMAP3 lists it as "usbhs_omap".
Attempting to get that clock from ehci-omap then fails. The solution
is to just change the clock3xxx_data.c for dummy clocks used in the
errata fix to match the dev_id, NULL, used in clock44xx_data.c.
Tested on BB-xM.

For a power domain to idle all the clock domains in it must idle.
This patch implements an optimization of the cpuidle code by
denying and later allowing only the first registered clock domain

Iteration over all power domains in the idle path is unnecessary since
only power domains that are transitioning need to be accounted for.
Also PRCM register accesses are known to be expensive, so the
additional latency added to the idle path is signficiant.
In order allow the pre/post transitions to be isolated and called
per-pwrdm, change the API so passing in a specific power domain will
trigger the pre/post transtion accounting for only that specific power
domain. Passing NULL means iterating over all power domains as is
current behavior.

IO Daisychain feature has to be triggered whenever there is a change in
device's mux configuration (See section 3.9.4 in OMAP4 Public TRM vP).
Now devices can idle independent of the powerdomain, there can be a
window where device is idled and corresponding powerdomain can be
ON/INACTIVE state. In such situations, since both module wake up is
enabled at padlevel as well as io daisychain sequence is triggered,
there will be 2 PRCM interrupts (Module async wake up via swakeup and
IO Pad interrupt). But as PRCM Interrupt handler clears the Module
Padlevel WKST bit in the first interrupt, module specific interrupt
handler will not triggered for the second time
