a920360f03 ARM: OMAP: TI81XX: Prepare for addition of TI814X support
This patch updates existing macros, functions used for TI816X, to enable
addition of other SoCs belonging to TI81XX family (e.g., TI814X).

The approach taken is to use TI81XX/ti81xx for code/data going to be common
across all TI81XX devices.

cpu_is_ti81xx() is introduced to handle code common across TI81XX devices.

In addition, ti8168_evm_map_io() is now replaced with ti81xx_map_io() and moved
in mach-omap2/common.c as same will be used for TI814X and is not board
specific.

9954119536 ARM: OMAP: am33xx: Update common omap platform files
This patch updates the common platform files with AM335X device
support (AM33XX family).

The approach taken in this patch is,
AM33XX device will be considered as OMAP3 variant, and a separate
SoC class created for AM33XX family of devices with a subclass type
for AM335X device, which is newly added device in the family.

This means, cpu_is_omap34xx(), cpu_is_am33xx() and cpu_is_am335x()
checks will return success on AM335X device.
A kernel config option CONFIG_SOC_OMAPAM33XX is added under OMAP3
to include support for AM33XX build.

Also, cpu_mask and RATE_IN_XXX flags have crossed 8 bit hence
struct clksel_rate.flags, struct prcm_config.flags and cpu_mask
are changed to u16 from u8.

cc1b0765da ARM: OMAP: hwmod: Fix the addr space, irq, dma count APIs
The address spaces, irqs and dma reqs count APIs return the
number of corresponding entries in a hwmod including a additional
null value or a -1 terminator in the structure introduced recently.
More information here:

- 212738a4: omap_hwmod: use a terminator record with omap_hwmod_mpu_irqs
  arrays

- 78183f3f: omap_hwmod: use a null structure record to terminate
  omap_hwmod_addr_space arrays

- bc614958: omap_hwmod: use a terminator record with omap_hwmod_dma_info
  arrays

The issue with irqs and dma info was originally reported by Benoit Cousson.

The devices which have multiple hwmods and use device_build_ss are
broken with this, as their resources are populated with a extra null
value, subsequently the probe fails. So fix the API not to include
the array terminator in the count.

b923d40dd4 ARM: OMAP2PLUS: DSS: Ensure DSS works correctly if display is enabled in bootloader
Resetting DISPC when a DISPC output is enabled causes the DSS to go into an
inconsistent state. Thus if the bootloader has enabled a display, the hwmod code
cannot reset the DISPC module just like that, but the outputs need to be
disabled first.

Add function dispc_disable_outputs() which disables all active overlay manager
and ensure all frame transfers are completed.

Modify omap_dss_reset() to call this function and clear DSS_CONTROL,
DSS_SDI_CONTROL and DSS_PLL_CONTROL so that DSS is in a clean state when the
DSS2 driver starts.

This resolves the hang issue(caused by a L3 error during boot) seen on the
beagle board C3, which has a factory bootloader that enables display. The issue
is resolved with this patch.

13662dc5b1 ARM: OMAP: HWMOD: Unify DSS resets for OMAPs
This patch adds a custom DSS reset function used on OMAPs from OMAP2
forward.

The function doesn't actually do a reset, it only waits for the reset to
complete. The reason for this is that on OMAP4 there is no possibility
to do a SW reset, and on OMAP2/3 doing a SW reset for dss_core resets
all the other DSS modules also, thus breaking the HWMOD model where
every DSS module is handled independently.

This fixes the problem with DSS reset on OMAP4, caused by the fact that
because there's no SW reset for dss_core on OMAP4, the HWMOD framework
doesn't try to reset dss_core and thus the DSS clocks were never enabled
at the same time. This causes causes the HWMOD reset to fail for
dss_dispc and dss_rfbi.

The common reset function will also allow us to fix another problem in
the future: before doing a reset we need to disable DSS outputs, which
are in some cases enabled by the bootloader, as otherwise DSS HW seems
to get more or less stuck, requiring a power reset to recover.

37ad085527 ARM: OMAP4: HWMOD: Add HWMOD_CONTROL_OPT_CLKS_IN_RESET for dss_core
DSS needs all DSS clocks to be enabled to be able to finish reset
properly. Before v3.1-rc1 the omapdss driver was managing clocks and
resets correctly. However, when omapdss started using runtime PM at
v3.1-rc1, the responsibility for the reset moved to HWMOD framework.

HWMOD framework does not currently enable all the DSS clocks when
resetting the DSS hardware. This causes the HWMOD frameworks boot-time
reset to fail, possibly leaving the DSS hardware in undefined state.

This patch sets HWMOD_CONTROL_OPT_CLKS_IN_RESET for dss_core. The flag
is actually not used on OMAP4, because dss_core hardware does not have
soft-reset functionality and thus the HWMOD framework never resets nor
waits for the reset to finish.

However, while the flag is not strictly needed currently, I think it
represents the HW correctly: all the DSS clocks should be enabled after
power-on to allow DSS hardware to finish its reset.

A custom reset function will be added in the following patches which
manages this correctly for OMAP4.

- dss_dsi is missing ick and sys_clk

- dss_venc is missing dss_96m_fck opt-clock, which is required on
  OMAP3430

- dss_venc's interface and main clocks are wrong, causing VENC to fail
  to start

These problems were temporarily fixed with a DSS patch
9ede365aa6 ("HACK: OMAP: DSS2: clk hack
for OMAP2/3"), which can be reverted after this patch (and the similar
patches for other OMAPs).

8c3105ca1a ARM: OMAP3: HWMOD: Fix DSS reset
DSS needs all DSS clocks to be enabled to be able to finish reset
properly. Before v3.1-rc1 the omapdss driver was managing clocks and
resets correctly. However, when omapdss started using runtime PM at
v3.1-rc1, the responsibility for the reset moved to HWMOD framework.

HWMOD framework does not currently enable all the DSS clocks when
resetting the DSS hardware. This hasn't caused any problems so far, but
we may just have been lucky.

dss_core's opt-clocks is also missing dss_96m_fck, which is a DSS clock
present only on OMAP3430, and thus required on OMAP3430 to finish the
reset.

This patch sets HWMOD_CONTROL_OPT_CLKS_IN_RESET and adds the dss_96m_fck
opt-clock for dss_core in OMAP3 HWMOD data, fixing the issue.

The OMAP2xxx HWMOD data currently contains two errors with DSS clocks:

- dss_rfbi is missing ick opt-clock, which is needed for RFBI to
  calculate timings

- dss_venc's interface and main clocks are wrong, causing VENC to fail
  to start

46bcfad7a8 cpuidle: Single/Global registration of idle states
This patch makes the cpuidle_states structure global (single copy)
instead of per-cpu. The statistics needed on per-cpu basis
by the governor are kept per-cpu. This simplifies the cpuidle
subsystem as state registration is done by single cpu only.
Having single copy of cpuidle_states saves memory. Rare case
of asymmetric C-states can be handled within the cpuidle driver
and architectures such as POWER do not have asymmetric C-states.

Having single/global registration of all the idle states,
dynamic C-state transitions on x86 are handled by
the boot cpu. Here, the boot cpu  would disable all the devices,
re-populate the states and later enable all the devices,
irrespective of the cpu that would receive the notification first.

4202735e8a cpuidle: Split cpuidle_state structure and move per-cpu statistics fields
This is the first step towards global registration of cpuidle
states. The statistics used primarily by the governor are per-cpu
and have to be split from rest of the fields inside cpuidle_state,
which would be made global i.e. single copy. The driver_data field
is also per-cpu and moved.
