ARM: s5pv210: use private pm save/restore The pm save/restore code is fairly small, so in order to separate the s3c and s5p platforms, adding an s5p specific copy instead of sharing it is actually easier.

ARM: samsung: make pm-debug platform independent The pm-debug code is one of the few things shared between s3c24xx/s3c64xx and the newer s5pv210. In order to make s5pv210 independent of plat-samsung, change the common bits of this code to no longer reference the s3c specific bits. In particular, all the CPU checks need to be moved out of the common code into platform specific files.

ARM: samsung: remove s3c_pm_debug_init() On s3c24xx and s3c64xx, this is just a wrapper around s3c_pm_debug_init_uart(), but this function does not exist on s5pv210, which always uses an empty stub as CONFIG_SAMSUNG_ATAGS is normally not set. In a configuration that supports both s5pv210 and s3c64xx, we would always call the s3c64xx function, which is probably incorrect when running on s5pv210. Remove the function call completely on s5pv210 and skip the wrapper on s3c as a cleanup. As a side-effect, the s3c64xx behavior is now always the same, regardless of whether it is a DT-only configuration or both DT and ATAGS are supported for booting.

pinctrl: samsung: Move retention control from mach-s5pv210 to the pinctrl driver This patch moves pad retention control from S5PV210 machine code to Exynos pin controller driver. This helps to avoid possible ordering and logical dependencies between machine and pin control code.

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.
