Stephen Warren 6bb27d7349 ARM: delete struct sys_timer
Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:
http://www.spinics.net/lists/arm-kernel/msg203686.html

Includes mach-omap2 fixes from Igor Grinberg.

Shawn Guo 50f2de6126 ARM: imx: include hardware.h rather than mach/hardware.h
It moves a bunch of header files included in hardware.h and itself
from mach-imx/include/mach to mach-imx, and updates users to include
hardware.h rather than mach/hardware.h.  The files in mach-imx/devices
will need to include "../hardware.h".

Shawn Guo e3372474cf ARM: imx: include common.h rather than mach/common.h
Rename mach-imx/include/mach/common.h to mach-imx/common.h and update
all users to include common.h rather than mach/common.h.

It also removes an unneeded inclusion to common.h in
mach-imx/devices/devices.c.

Benoît Thébaudeau 33a264ddcd ARM: imx: cleanup otg_mode
Cleanup the code for the otg_mode command line param:
* Use the bool type as it applies here.
* Qualify otg_mode_host with __initdata since this variable is only used in this
  context.
* The __setup functions are not supposed to return a status code, but a boolean
  indicating whether the param has been handled. See obsolete_checksetup() in
  init/main.c.

Shawn Guo b78d8e59a6 gpio/mxc: Change gpio-mxc into an upstanding gpio driver
The patch makes necessary changes on gpio-mxc as below to turn it
into an upstanding gpio driver.

 * Add a list to save all mx2 ports references, so that
   mx2_gpio_irq_handler can walk through all interrupt status
   registers

 * Use readl/writel to replace mach-specific accessors
   __raw_readl/__raw_writel

 * Change mxc_gpio_init into mxc_gpio_probe function

 * Move "struct mxc_gpio_port" into gpio-mxc.c, as it needs not to
   be public at all, and also make some other cleanup on
   plat-mxc/include/mach/gpio.h at the same time

And the patch then migrates mach-imx and mach-mx5 to the updated
driver by adding corresponding platform devices.

Uwe Kleine-König f4bf03d8b7 ARM: imx: remove #includes already available from devices-common.h
Most machine files include "devices-imxXX.h" which in turn includes
<mach/devices-common.h>.  The latter already includes many headers
that the machine files don't need to include again.

These were found by:

 $ grep \#include arch/arm/plat-mxc/include/mach/devices-common.h > tmpfile
 $ git grep -l 'devices-imx' arch/arm | xargs grep -f tmpfile -F

(but I kept linux/init.h, linux/kernel.h and linux/platform_device.h)

Sascha Hauer 4bd597b633 ARM i.MX ehci: do ehci init in board specific functions
The mxc-ehci driver calls SoC specific phy initialization right after
calling board specific initialization. To offer greater flexibility for
boards to setup the phy and to get rid of some unnecessary flags in
platform data this patch lets the boards call the SoC specific phy
initialization and remove it from the driver.

Lothar Waßmann 8f5260c8c1 ARM: i.MX IOMUX-V3 replace struct pad_desc with bitmapped cookie
The following patch is a first step to convert the 'struct pad_desc'
to a bitmapped cookie to facilitate adding platform specific pullup or
drive strength definitions to existing pad definitions without need to
rewrite the complete pad def.

The patch wraps 'struct pad_desc' in an opaque data type and
introduces macros to access the individual members.
This patch does not constitute any functional change!
