5cfc5220a6 ARM: pxa: Remove unused clock_enable field from struct pxa2xx_spi_master
Use for struct pxa2xx_spi_master clock_enable field was removed years ago
from the pxa2xx-spi driver by the commit 2f1a74e5a2 ("[ARM] pxa: make
pxa2xx_spi driver use ssp_request()/ssp_free()").

Therefore remove it from structure definition, documentation and from
couple affected board files.

a927ef895e ARM: pxa: fix dm9000 platform data regression
Since dm9000 driver added support for a vcc regulator, platform data
based platforms have their ethernet broken, as the regulator claiming
returns -EPROBE_DEFER and prevents dm9000 loading.

This patch fixes this for all pxa boards using dm9000, by using the
specific regulator_has_full_constraints() function.

This was discovered and tested on the cm-x300 board.

Fixes: 7994fe55a4 ("dm9000: Add regulator and reset support to dm9000")

This patch replaces power callbacks to the regulator API. To improve
the readability of the code, helper for the regulator enable/disable

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.

851982c1b6 ARM: pxa: Introduce pxa{25x,27x,3xx}_map_io()
This patch introduces pxa2xx_map_io() and pxa3xx_map_io() to distinguish
between PXA25x/PXA27x and PXA3xx memory mapping.

Also, fixup for platforms broken after introducing pxa{25x,27x}_map_io()
and pxa3xx_map_io() is included.

8348c259dd arm/pxa2xx: reorgazine SSP and SPI header files
The PXA-SPI driver relies on some files / defines which are arm specific
and are within the ARM tree. The CE4100 SoC which is x86 has also the
SPI core.
This patch moves the ssp and spi files from arm/mach-pxa and plat-pxa to
include/linux where the CE4100 can access them.

This move got 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

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 ]

e446630c96 Add hotplug support to mcp251x driver
Chip model can now be selected directly by matching the modalias name
(instead of filling the .model field in platform_data), and allows the
module to be auto-loaded. Previous behaviour is of course still supported.

Convert the two in-tree users to this feature (icontrol & zeus).
Tested on an Zeus platform (mcp2515).
