Rafael J. Wysocki 2eaa03b5be ARM / PXA: Use struct syscore_ops for "core" power management
Replace sysdev classes and struct sys_device objects used for "core"
power management by the PXA platform code with struct syscore_ops
objects that are simpler.

This reduces the code size and the kernel memory footprint.  It also
is necessary for removing sysdevs entirely from the kernel in the
future.

Sebastian Andrzej Siewior b459396ee9 ARM: pxa2xx: reorganize I2C files
This patch moves the platform data definition from
arch/arm/plat-pxa/include/plat/i2c.h to include/linux/i2c/pxa-i2c.h so
it can be accessed from x86 the same way as on ARM.

This change should make no functional change to the PXA code. The move
is verified by building the following defconfigs:
  cm_x2xx_defconfig corgi_defconfig em_x270_defconfig ezx_defconfig
  imote2_defconfig pxa3xx_defconfig spitz_defconfig zeus_defconfig
  raumfeld_defconfig magician_defconfig mmp2_defconfig pxa168_defconfig

Russell King - ARM Linux 4321e1a12b 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().

Russell King b75c178afa ARM: P2V: avoid initializers and assembly using PHYS_OFFSET
As PHYS_OFFSET will be becoming a variable, we can't have it used in
initializers nor assembly code.  Replace those in generic code with
a run-time initialization.  Replace those in platform code using the
individual platform specific PLAT_PHYS_OFFSET.

Nicolas Pitre 6451d7783b arm: remove machine_desc.io_pg_offst and .phys_io
Since we're now using addruart to establish the debug mapping, we can
remove the io_pg_offst and phys_io members of struct machine_desc.

The various declarations were removed using the following script:

  grep -rl MACHINE_START arch/arm | xargs \
  sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'

[ Initial patch was from Jeremy Kerr, example script from Russell King ]

Russell King cc155c6f2c [ARM] pxa: allow platforms to control which uarts are registered
For some platforms, it is inappropriate to register all PXA UARTs.
In some cases, the UARTs may not be used, and in others we may want
to avoid registering the UARTs to allow other drivers (eg, FICP) to
make use of the UART.

In addition, a while back there was a request to be able to pass
platform data to the UART driver.

This patch enables all of this by providing functions platforms can
call to register each individual UART.

 * Move to __raw_readl/__raw_writel for FPGA/CPLD register access
 * Change Toppoly LCD config to be selectable at run time rather than
   compile time.
 * Remove currently unused irq device suspend/resume functions.
 * Strip out unnecessary/duplicated #includes.
 * Some code style cleanups.
