058af1ea98 omap: GPIO module enable/disable
This patch disables a GPIO module when all pins of a GPIO
module are inactive (clock gating forced at module level) and
enables the module when any gpio in the module is requested.

The module is enabled only when "mod_usage" indicates that no GPIO
in that  module is currently active and the GPIO being requested
is the 1st one to be active in that module.

Each module would be disabled in omap_gpio_free() API when all
GPIOs in a particular module becomes inactive. The module is
re-enabled in omap_gpio_request() API when a GPIO is requested
from the module that was previously disabled.

Since individual GPIO's bookkeeping is added in this patch
via "mod_usage", the same is used in omap_set_gpio_debounce()
& omap_set_gpio_debounce_time() APIs to ensure that the gpio being
used is actually "requested" prior to being used (Nishant Menon's
<nm@ti.comSuggestion)

GPIO module level details are specific to hardware and hence
introducing this patch in low level layer (plat-omap/gpio.c)

13a0322957 omap3: drop all IVA-related address base definitions
All of the OMAP3 IVA physical address macros in
plat-omap/include/plat/omap34xx.h are wrong[1]:

OMAP34XX_IVA_INTC_BASE: The IVA interrupt controller does not appear
to be accessible from the L3 interconnect, and in any case is
definitely not at 0x40000000; the latter address appears to be the
internal IVA physical address base for the OMAP2420's interrupt control[2].

OMAP34XX_DSP_BASE: The section of L3 physical address space mapped to
the IVA starts at 0x5c000000, not 0x58000000.

OMAP34XX_DSP_MEM_BASE: It's not clear what this refers to, but it's not
in the L3 IVA address space.

OMAP34XX_DSP_IPI_BASE: The Intrusive Port Interface is a relic from
the OMAP2420 days and no longer applies to OMAP3.

OMAP34XX_DSP_MMU_BASE: The DSP MMU is mapped at 0x5d000000, not 0x5a000000.


Nothing that uses these can possibly be working, so drop them.  When
future code needs these, correct versions can be added in.

2456a10fb3 omap3: Introduce OMAP3630
OMAP3630 is the latest in the family of OMAP3 devices
and among the changes it introduces are:

New OPP levels for new voltage and frequency levels. a bunch of
Bug fixes to various modules feature additions, notably with ISP,
sDMA etc.

Details about the chip is available here:
http://focus.ti.com/general/docs/wtbu/wtbuproductcontent.tsp?templateId=6123&navigationId=12836&contentId=52606

Strategy used:
Strategy to introduce this device into Linux was discussed here:
Ref: http://marc.info/?t=125343303400003&r=1&w=2

Two approaches were available:
a) Consider 3630 generation of devices as a new family of silicon
b) Consider 3630 as an offshoot of 3430 family of devices

As a common consensus, (b) seems to be more valid for 3630 as:
* There are changes which are easily handled by using "FEATURES"
  infrastructure.
  For details how to do this, see thread:
  http://marc.info/?t=125050998500001&r=1&w=2
* Most of existing 34xx infrastructure can be reused(almost 90%+)
	- so no ugly if (cpu_is_omap34xx() || cpu_is_omap36xx())
	  all over the place
	- lesser chance of bugs due to reuse of proven code flow
	- 36xx specific handling can still be done where required
	  within the existing infrastructure

NOTE:
* If additional 34xx series are added, OMAP3430_REV_ESXXXX can be
  added on top of the existing 3630 ones are renumbered

This patch was tested on SDP3430, boot tested on 3630 platform using
3430sdp defconfig

45f780a061 omap1: omap_udc: Add clocking and disable vbus sense for omap7xx
The l3_ocpi_ck clock is needed on omap7xx processors for USB.
Additionally, bit 8 of the SOFT_REQ_REG needs to be enabled for
the usb_dc_ck on omap7xx, which is a different bit than that
of the omap16xx-defined clock of the same name.

I added a provision for the usb_dc_ck and l3_ocpi_ck clocks as
dc_clk and hhc_clk, respectively, for omap7xx CPUs.  Additionally,
I added a check in machine_without_vbus_sense for all omap7xx
devices, as presently I know of no omap7xx-based devices that
have vbus sense, and it made more sense to me to use a cpu check
here than to spell out each machine one at a time.  Finally, DMA
is disabled for omap7xx, as it causes problems with these chips.

490a566522 omap1: mmc: Add platform init for omap7xx
The MMC mux pins normally used by omap chips in devices.c
are different from what is needed by omap7xx chips.  This
change adds a conditional around the mux setup code to
enable the correct mux pins.

The omap730 and omap850 both use a different clock for the "fck"
clock of the MMC interface than other omap processors based on the
SOFT_REQ_REG, pin 12.  The "ick" clock is the same as that used
by other omap processors.

* Added the missing clock definition as mmc3_ck to clock.h
* Added the clock definition to omap_clks in clock.c
* Added CK_7XX to the mmci-omap.0 "ick" clock already in clock.c

With these changes, it is now possible to initialize and use MMC
cards with omap730 and omap850 devices.

f265dc4c5d OMAP3: PM: Program SDRC to send self refresh on timeout of AUTO_CNT
Due to an OMAP3 errata (1.142), on HS/EMU devices SDRC should be
programed to issue automatic self refresh on timeout
of AUTO_CNT = 1 prior to any transition to OFF mode.
This is needed only on sil rev's ES3.0 and above.

This patch enables the above needed WA in the SDRC power register
value stored in scratchpad, so that ROM code restores this value
in SDRC POWER on the wakeup path.
The original SDRC POWER register value is stored and restored back
in omap_sram_idle() function.

This fixes some random crashes observed while stressing suspend
on HS/EMU devices.

ba50ea7eb9 OMAP3: PM: Fix secure SRAM context save/restore
The secure sram context save uses dma channels 0 and 1.
In order to avoid collision between kernel DMA transfers and
ROM code dma transfers, we need to reserve DMA channels 0
1 on high security devices.

A bug in ROM code leaves dma irq status bits uncleared.
Hence those irq status bits need to be cleared when restoring
DMA context after off mode.

There was also a faulty parameter given to PPA in the secure
ram context save assembly code, which caused interrupts to
be enabled during secure ram context save. This caused the
save to fail sometimes, which resulted the saved context
to be corrupted, but also left DMA channels in secure mode.
The secure mode DMA channels caused "DMA secure error with
device 0" errors to be displayed.

8561a84f85 omap: Fix omapfb/lcdc on OMAP1510 broken when PM set
With CONFIG_PM=y, the omapfb/lcdc device on Amstrad Delta, after initially
starting correctly, breaks with the following error messages:

omapfb omapfb: resetting (status 0xffffff96,reset count 1)
...
omapfb omapfb: resetting (status 0xffffff96,reset count 100)
omapfb omapfb: too many reset attempts, giving up.

Looking closer at this I have found that it had been broken almost 2 years ago
with commit 2418996e3b100114edb2ae110d5d4acb928909d2, PM fixes for OMAP1.

The definite reason for broken omapfb/lcdc behavoiur in PM mode
appeared to be ARM_IDLECT1:IDLIF_ARM (bit 6) put into idle regardless of LCD
DMA possibly running. The bit were set based on return value of the
omap_dma_running() function that did not check for dedicated LCD DMA
channel status. The patch below fixes this.

Note that the hardcoded register value will be fixed during the next merge
cycle to use OMAP_LCDC_ defines. Currently the OMAP_LCDC_ defines are local
to drivers/video/omap/lcdc.c, so let's not start moving those right now.

Created against linux-2.6.32-rc6

a9f82d10d1 omap: Fix incorrect 730 vs 850 detection
Commit cd92204924 added
support for omap850. However, the patch accidentally
removed the wrong ifdef:

 #  define cpu_is_omap730()		1
 # endif
 #endif
+#else
+# if defined(CONFIG_ARCH_OMAP850)
+#  undef  cpu_is_omap850
+#  define cpu_is_omap850()		1
+# endif
+#endif

...

 void omap2_check_revision(void);

 #endif    /* defined(CONFIG_ARCH_OMAP2) || defined(CONFIG_ARCH_OMAP3) */
-
-#endif

Instead of removing removing the #endif at the end of the file,
the #endif before #else should have been removed.

But we cannot have multiple #else statements as pointed out by
Alistair Buxton <a.j.buxton@gmail.com>. So the fix is to:

- remove the non-multi-omap special handling, as we need to
  detect between omap730 and omap850 anyways.

- add the missing #endif back to the end of the file

ee894b18e0 OMAP3: PM: introduce a new powerdomain walk helper
The 'pwrdm_for_each()' function walks powerdomains with a spinlock
locked, so the the callbacks cannot do anything which may sleep.
This patch introduces a 'pwrdm_for_each_nolock()' helper which does
the same, but without the spinlock locked. This fixes the following
lockdep warning:

44e74840d6 omap: Fix MMC gpio_wp for BeagleBoard C2 and above
Earlier BeagleBoards were using pad AH8 muxed to GPIO29 for MMC write-protect.
However, this signal has been changed to pad AG9 in board revision C2.

Fix this by adding mux configuration for pad AG9, runtime check for board
revisions and set the gpio number and pad muxing accordingly.
