3e7a728117 [ARM] 5343/1: ep93xx: include linux/i2c.h
Include <linux/i2c.h> in all ep93xx platforms.

Patch "5311/1: add core support for built in i2c bus" will cause build errors due to the following in
arch/arm/mach-ep93xx/include/mach/platform.h:

+void ep93xx_register_i2c(struct i2c_board_info *devices, int num);

The i2c.h header needs to be included in order to define struct i2c_board_info.

The following patch changes the flash memory hard-coded resource

1124d6d21f [ARM] dma: correct dma_supported() implementation
dma_supported() is supposed to indicate whether the system can support
the DMA mask it was passed, which depends on the maximal address which
can be returned for DMA allocations.  If the mask is smaller than that,
we are unable to guarantee that the driver can reliably obtain suitable
memory.

37787e449b [ARM] Kirkwood: properly handle the WAN port on newer RD88F6281 boards
On newer versions of the RD88F6281 board, the WAN port is connected to
its own ethernet port on the CPU, via a separate PHY, whereas on older
versions of the board, it is connected to one of the PHYs in the
ethernet switch.  In the RD8F6281 setup code, detect which version of
the board we are running on, and instantiate the ethernet ports and

a0361a8afe [ARM] pxa/MioA701: change reset function to preserve RTC.
Change the halt and reboot method from gpio based to "jump
to ROM IPL beginning". This gives control back to IPL, which
without PowerOn key pressed, will put the device into deep
sleep until PowerOn is pressed for 1 second.

But this has the benefit of keeping the RTC registers across
reboots, which is good for OS change.

65587f7d15 [ARM] pxa: cpufreq-pxa2xx: allow frequency table selection
Following the removal of the "->policy" usage for PXA255 in patch
459fc208ab (cpufreq: remove
policy->governor setting in drivers initialization), this patch
introduces an option (called "pxa255_turbo_table") to select either
the "run" or "turbo" frequency table.

It also cures the runtime warning that was printed each time the
frequency was changed.

Got rid of all references to CPUFREQ_POLICY_* for pxa255, and sticked
with the run/turbo thing.

Tested on an Arcom/Eurotech Viper.

067455aa53 [ARM] pxa: add support for additional GPIOs on PXA26x
Original patch from Marek Vasut, the problems with PXA26x are:

1. there are additional 4 GPIOs 86,87,88,89 have their direction bits
   inverted in GPDR2, as well as their alternate function bits being
   '1' for their GPIO functionality in GAFRx

2. there is no easy way to decide if the processor is a pxa26x or a
   pxa250/pxa255 at run-time, so the assumption here is the pxa26x
   will be treated as one of the pxa25x variants, and board code
   should have a better knowledge of the processor it is featured

Introduce pxa26x_init_irq() for the second purpose, and treat the
additional GPIOs > 85 on PXA25x specially.

Kconfig option CONFIG_CPU_PXA26x is introduced to optimize the code
a bit when PXA26x support isn't needed. Board config options have
to select this to enable the support for PXA26x.

__gpio_is_inverted() will be optimized way when CONFIG_CPU_PXA26x
isn't selected.

Also, fix the incorrect GPIO number passed in pxa27x_init_irq().

93982535a2 [ARM] 5336/1: Formatting/Whitespace cleanups in mach-sa1100
This patch fixes bad formatting found in
mach-sa1100 files.

What it does is to replace/delete things like
excessive spaces (start || endline). The code
looks the same just alot less junk.

799a0600ac [ARM] 5324/2: ep93xx: support gpio interrupt debounce
Add debounce support for ep93xx gpio interrupts.

On the EP93xx, GPIO ports A, B, and F can be used to generate
interrupts. For each port, if interrupts are enabled, it is
possible to debouce the input signal. Debouncing is implemented
by passing the input signal through a 2-bit shift register clocked
by a 128Hz clock.

This patch adds a platform specific way to enable the debouce
feature for these input ports.

Allow the ep93xx platform init code to register the built-in i2c bus.

The EP93xx processor has two GPIO pins dedicated for an I2C bus. This
patch registers the platform supplied i2c_board_info and the necessary
platform_device information for the i2c-gpio driver to use these pins.

7be90a6ba9 [ARM] 5319/1: AT91: support AT91CAP9 revC CPUs
The AT91CAP9 revC CPU has a few differences over the previous,
revB CPU which was distributed in small quantities only (revA was
an internal Atmel product only).

This patch adds the detection routines to recognize the different
AT91CAP9 revisions (based on the PMC subsystem version number), and
uses them to:
	- activate a workaround for the external interrupts levels
	  (on revB CPUs)
	- set the UDPHS_BYPASS bit (on revB CPUs)
	- set AT91_GPBR register address to the correct offset
	  (0xfffffd50 on revB, 0xfffffd60 on revC)

For debugging usage, the CPU revision can be found in /proc/cpuinfo
on the 'Revision' line.

This patch is extracted from Andrew Victor's -at91 patch (2.6.27-at91.patch)
where it has been tested for the last 6 months.

This allows us to remove a lot of mach/dma.h files which don't contain

private non-ISA definitions into mach/dma.h, so we leave these behind
and fix the appropriate #include statments.
