2014-12-17ARM: dts: update watchdog device nodes for exynos5250 and exynos5420Leela Krishna Amudala1-0/+9
In EXYNOS5 series SoCs, PMU has registers to enable/disable mask/unmask watchdog timer which is not the case with s3c series SoCs so, there is a need to have different compatible names for watchdog to handle these pmu registers access. Hence this patch removes watchdog node from Exynos5.dtsi common file and make it separate by updating existing node in Exynos5250 and adding new node to Exynos5420.

In preparation of adding support for EXYNOS5420, which has many peripherals similar to EXYNOS5250, a new common EXYNOS5 device tree source file is created out of the exising EXYNOS5250 device tree source file. Only the common nodes required for basic boot up on EXYNOS5420 based boards are moved into this new file and the rest of the common nodes would be moved subsequently. EXYNOS5440 SoC is quite different from EXYNOS5250 and EXYNOS5420. Hence it is not possible to reuse "exynos5.dtsi" for EXYNOS5440.

2014-12-17i2c: exynos5: Properly use the "noirq" variants of suspend/resumeDoug Anderson1-2/+10
The original code for the exynos i2c controller registered for the "noirq" variants. However during review feedback it was moved to SIMPLE_DEV_PM_OPS without anyone noticing that it meant we were no longer actually "noirq" (despite functions named exynos5_i2c_suspend_noirq and exynos5_i2c_resume_noirq). i2c controllers that might have wakeup sources on them seem to need to resume at noirq time so that the individual drivers can actually read the i2c bus to handle their wakeup. NOTE: I took the original review feedback from Wolfram and added poweroff, thaw, freeze, restore. This patch has only been compile-tested since I don't have all the patches needed to make my machine using this i2c driver actually suspend/resume.

2014-12-17sched: replace INIT_COMPLETION with reinit_completionWolfram Sang1-3/+15
For the casual device driver writer, it is hard to remember when to use init_completion (to init a completion structure) or INIT_COMPLETION (to *reinit* a completion structure). Furthermore, while all other completion functions exepct a pointer as a parameter, INIT_COMPLETION does not. To make it easier to remember which function to use and to make code more readable, introduce a new inline function with the proper name and consistent argument type. Update the kernel-doc for init_completion while we are here.
