ba7a9a784f ARM: SAMSUNG: Remove unnecessary code for dma
This patch removes the usage of DMACH_DT_PROP and dt_dmach_prop
from dma code as the new generic dma dt binding support has been
added.

bd338d0708 ARM: S3C24XX: remove unneeded "config SMDK2440_CPU2442"
The Kconfig entry for SMDK2440_CPU2442 was moved from one Kconfig file
to another in commit acf2d41d85 ("ARM: S3C24XX: Move mach-s3c2440/
pll into mach-s3c24xx/"). In that move it also lost its statement to
select CPU_S3C2442. That was not needed anymore because it now depended
on that same symbol.

But without its select this entry became a nop: enabling it has no
effect, as it changes no code. It can safely be removed.

Fix a related, and trivial, comment typo too.

The Kconfig entry for the Openmoko GTA02 / Freerunner

b274776c54 arm-soc: cleanups
A large number of cleanups, all over the platforms. This is dominated
 largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
 others moving code out of arch/arm into more appropriate subsystems.
 The clocksource and irqchip drivers are now abstracted to the point
 where platforms that are already cleaned up do not need to even specify
 the driver they use, it can all get configured from the device tree
 as we do for normal device drivers. The clocksource changes basically
 touch every single platform in the process.
 
 We further clean up the use of platform specific header files here,
 with the goal of turning more of the platforms over to being
 "multiplatform" enabled, which implies that they cannot expose
 their headers to architecture independent code any more.
 
 It is expected that no functional changes are part of the cleanup.
 The overall reduction in total code lines is mostly the result of
 removing broken and obsolete code.

The code to enter sleep is used by both the s3c2412 and s3c2416 and
was thus factored out into an extra config option.

But it seems it was forgotten to add the appropriate select to the
s3c2412 pm option, resulting in breakage when only compiling s3c2412
support.

This patch is for just moving plat-s3c24xx/*.c into mach-s3c24xx/, so
that we could remove plat-s3c24xx directory. But since the PLAT_S3C24XX
is used in drivers, the statement is not deleted and it will be sorted
out next time.

b499b7a871 ARM: S3C24XX: modify s3c2443 irq init to initialize all irqs
Previously the irq init used s3c24xx_init_irq and an additional
arch_initcall to add the cpu specific irqs.

To be able to simplyfy the irq init later, create a new function
s3c2443_init_irq, which then calls s3c24xx_init_irq but also adds
the cpu specific irqs.

d3fcacf52d ARM: SAMSUNG: Gracefully exit on suspend failure
As per the Exynos5250 User Manual:
When there are pending interrupt events, WFI/WFE instruction are
ignored. To cancel the power-down sequence follow these steps:
1) Disable system power-down using CENTRAL_SEQ_CONFIGURATION register
2) Clear WAKEUP_STAT register
3) Enable interrupt service routine for CPU

Code for early wakeup for exynos already exists. Remove the panic
on suspend failure, clear the wakeup state register and return 1
from cpu_suspend to indicate a failed suspend (to a user daemon).

Older Samsung SoCs have similar panics and I have removed them all.
Haven't touched the S3C2410 sleep code.
