In function si_parse_power_table(), array adev->pm.dpm.ps and its member

is freed and returned with an error code. However, the array is later
freed again in si_dpm_fini() function which is called when the function

PXA is now ready to be built into a single kernel with all the
other ARMv5 platforms, so change the Kconfig bit to finish it
off. The mach/uncompress.h support is the last bit that goes away,
getting replaced with the normal DEBUG_LL based approach.

Using MTD-XIP does not work on multiplatform kernels because
it requires SoC specific register accesses to be done from
low-level flash handling functions in RAM while the rest of the
kernel sits in flash.
I found no evidence of anyone still actually using this feature,
so re

None of the headers are included from outside of the mach-pxa

On a kernel that includes both ARMv4 and XScale support,
the copypage function fails to build with invalid
instructions.
Since these are only called on an actual XScale processor,
annotate the assembly with the correct .arch directive.

There are two drivers in arch/arm/plat-pxa: mfp and ssp. Both
of them should ideally not be needed at all, as there are
proper subsystems to replace them.
OTOH, they are self-contained and can simply be normal
SoC drivers, so move them over there to eliminate one more

In a multiplatform kernel that includes both pxa and mmp, we get a link
failure from the clash of two pxa_register_device functions.
Rename the one in mach-mmp to mmp_register_device, along with with the
rename of pxa_device_desc.

There are two tavorevb boards in the kernel, one using a PXA930 chip in
mach-pxa, and one using the later PXA910 chip in mach-mmp. They use the
same board number, which is generally a bad idea, and in a multiplatform
kernel, we can end up with funny link errors like this one

The sa.h header defines some constants using the bitfield
macros, but those are only used on sa1100, not on pxa, and the
users include the bitfield header through mach/hardware.h.

The battery driver uses a lot of GPIO lines, hardcoded from a
machine header file.
Change it to use a gpiod lookup table instead.

We have three power supplies that need similar initialization.
As a preparation for the gpio lookup table conversion, split

The clock register definitions are now used (almost) exclusively in the
clk driver, and that relies on no other mach/*.h header files any more.

as offsets from a void __iomem * pointer, which is either pass

The driver needs some low-level register access for setting
the core and bus frequencies. These registers are owned
by the clk driver, so move the low-level access into that
driver with a slightly higher-level interface and avoid
any machine header file dependencies.

get_clk_frequency_khz() is not a proper name for a global function,
and there is only one caller.
Convert viper to use the properly namespaced
pxa25x_get_clk_frequency_khz() and remove the other references.

Rather than poking at the smemc registers directly from the
pcmcia/pxa2xx_base driver, move those bits into machine file
to have a cleaner interface.
