Subject: ARM: pxa: Use gpio arrays in palmld_hdd driver

Use gpio_request_array() / gpio_free_array(), this makes the code
cleaner and less error prone.

This patch also properly frees GPIOs in case ata_host_activate() call fails.

Subject: ARM: pxa: clean up set_pxa_fb_info

set_pxa_fb_info() has been a long-standing wart in the naming scheme
of the pxa_set_xxx_info() functions.  This renames the function, and
combines set_pxa_fb_parent() with set_pxa_fb_info().

Subject: ARM: pxa25x_udc: stop handling gpio-vbus internally

Stop handling gpio-vbus internally. All boards that depended on this
functionality have been converted to use gpio-vbus tranceiver. All
new boards can use it right from the start. Drop unused code.

Subject: ARM: pxa: drop gpio_vbus field from pxa2xx_udc_mach_info

Neither pxa25x_udc, nor pxa27x_udc use gpio_vbus/gpio_vbus_inverted
anymore. Drop those two fields from udc info completely.

Subject: ARM: pxafb: rework pxafb overlay memory management

PXAFB overlay memory management is something messy:
- it allocates memory dynamically on open/release, and it results
  in memory allocation failure after ~1h of uptime (system does not have
  115k of physically contiguous memory)
- in release callback it tries to free memory even if it was not
  allocated.

Also driver touches FDADR1 on main plane reconfiguration, and it can cause
problems if overlay1 is enabled.

This patch attempts to fix those issues.

Patch is based on Russell King's work.

Subject: ARM: pxafb: don't disable controller on cpufreq transition if overlay
 in use

It's not safe to disable controller if overlay(s) is enabled (results in
system hang). So we avoid to disable controller in this case. Userspace
should choose proper governor to avoid freq changing when overlay is in
use, otherwise LCD may blink.

Subject: ARM: mx51: Print silicon revision on boot

Having the silicon revision to appear on the boot log is a useful information.

MX31 and MX35 already show the silicon revision on boot.

Add support for displaying such information for MX51 as well.

Tested on a MX51EVK, where it shows:

CPU identified as i.MX51, silicon rev 3.0

Current code inside babbage_fec_reset uses gpio_direction_output with initial value of the GPIO and also sets
the GPIO value via gpio_set_value to the same level right after. This is not needed.

By using gpio_request_one it is possible to set the direction and initial value in one shot.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As there is a mx53_smd board in the kernel, using SMD_FEC_PHY_RST as the pin name can be misleading when used
on a MX53_EVK board.

Change the pin name to reflect the board name.

mach-imx27_visstrim_m10.c uses imx27_add_imx_ssi() so it needs to select
IMX_HAVE_PLATFORM_IMX_SSI to fix:

	arch/arm/mach-imx/built-in.o: In function `visstrim_m10_board_init':
	mach-imx27_visstrim_m10.c:(.init.text+0x308): undefined reference to `imx_add_imx_ssi'

Subject: ARM: mx51_efika: update platform data for new mfd changes

Note that this relies on stuff currently in mfd's next tree, but this
is also a newer driver.  I'm not sure which tree it should go through,
as it's a problem that shows up in next.

From: Andres Salomon <dilinger@queued.net>

MFD changes in c738892f cause the mc13xxx_platform_data struct
to change.  This changes one more (new) user of it, fixing a build
error.
