b5f6517948 spi: sunxi: Add Allwinner A10 SPI controller driver
The older Allwinner SoCs (A10, A13, A10s and A20) all have the same SPI
controller.

Unfortunately, this SPI controller, even though quite similar, is significantly
different from the recently supported A31 SPI controller (different registers
offset, split/merged registers, etc.). Supporting both controllers in a single
driver would be unreasonable, hence the addition of a new driver.

Like its more recent counterpart, it supports DMA, but the driver only does PIO
until we have a dmaengine driver for this platform.

9b87a5b0d4 ASoC: pxa: Remove superfluous locking
The locking here was added in commit 71a295602e ("ASoC: Lock the CODEC in PXA
external jack controls") to protect the DAPM changes that are made inside of
${board}_ext_control() against concurrent updates. The ASoC core was updated in
commit a73fb2df01 ("ASoC: dapm: Use DAPM mutex for DAPM ops instead of codec
mutex") to use a card wide lock rather the CODEC mutex to protect DAPM
operations. We now have proper locking inside ${board}_ext_control() itself, so
taking the CODEC lock can be removed.

This reverts commit d8a5dc3033.

This breaks plymouth installs, either because plymouth is using the file
"incorrectly" or because the patch is incorrect.  Either way, this needs
to be reverted until it is all figured out.

c093e1d36e ahci_platform: Drop support for imx53-ahci platform device type
Since the 3.13 release the ahci_imx driver has proper devicetree enabled
support for ahci on imx53 and that is used instead of the old board file
created imx53-ahci platform device.

Note this patch also complete drops the id-table, an id-table is not needed
for a single id platform driver, the name field in the driver struct suffices.

And the code already has an explicit "MODULE_ALIAS("platform:ahci");" so the
id-table is not needed for that either.

ba5a37e521 ARM: mvebu: Move kirkwood DT boards into mach-mvebu
Move the kirkwood DT support into mach-mvebu, and make them part of
ARCH_MULTI_V5. Minimal changes have been made in order to make it
boot. Cleanup of the header files and integration with mvebu will
take place in following patches.

In order to help Debian transition between mach-kirkwood and
mach-mvebu, the DTS files are compiled for both, allowing Debian to
continue using mach-kirkwood until all remaining boards are supported
by mach-mvebu. Debian is then expected to simply swap from
mach-kirkwood to mach-mvebu and mach-kirkwood will be removed.

2) Enable resources, handled by ahci_platform_enable_resouces
3) The more or less standard ahci-host controller init sequence

This commit refactors step 1 and 3 into separate functions, so the platform
drivers for AHCI implementations which need a specific order in step 2,
and / or need to do some custom register poking at some time, can re-use
ahci-platform.c code without needing to copy and paste it.

Note that ahci_platform_init_host's prototype takes the 3 non function
members of ahci_platform_data as arguments, the idea is that drivers using
the new exported utility functions will not use ahci_platform_data at all,
and hopefully in the future ahci_platform_data can go away entirely.

039ece38da libahci: Allow drivers to override start_engine
Allwinner A10 and A20 ARM SoCs have an AHCI sata controller which needs a
special register to be poked before starting the DMA engine.

This register gets reset on an ahci_stop_engine call, so there is no other
place then ahci_start_engine where this poking can be done.

This commit allows drivers to override ahci_start_engine behavior for use by
the Allwinner AHCI driver (and potentially other drivers in the future).
