Merge tag 'samsung-fixes-3' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into fixes
Merge "Samsung fixes-3 for 3.16" from Kukjin Kim:
Samsung fixes-3 for v3.16
- update the parent for Auudss clock because kernel will be hang
during late boot if the parent clock is disabled in bootloader.
- enable clk handing in power domain because while power domain
on/off, its regarding clock source will be reset and it causes
a problem so need to handle it.
- add mux clocks to be used by power domain for exynos5420-mfc
during power domain on/off and property in device tree also.
- register cpuidle only for exynos4210 and exynos5250 because a
system failure will be happened on other exynos SoCs.
* tag 'samsung-fixes-3' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung:
ARM: EXYNOS: Register cpuidle device only on exynos4210 and 5250
ARM: dts: Add clock property for mfc_pd in exynos5420
clk: exynos5420: Add IDs for clocks used in PD mfc
ARM: EXYNOS: Add support for clock handling in power domain
ARM: dts: Update the parent for Audss clocks in Exynos5420
