2015-06-10clk: exynos5433: Add CLK_IGNORE_UNUSED flag to clocks for SMCJonghwa Lee1-18/+18
This patch adds 'CLK_IGNORE_UNUSED' flag to clocks which is required for operation of secure monitor call (smc). System will hang when it executes 'smc' with one of those clock is gated. All related clocks must be enabled.

2015-06-10clk: exynos5433: Add clock flag to support the DVFS of GPUJoonyoung Shim1-9/+9
This patch adds the CLK_SET_RATE_PARENT flag for 'aclk_g3d' clock and parent clocks becuase 'aclk_g3d' is used to change GPU frequency for DVFS (Dynamic Voltage Frequency Scaling) feature and adds CLK_IGNORE_UNUSED flags to 'aclk_asyncapbs_g3d'/'aclk_asyncapbm_g3d' clocks to access the SFR of the MALI device.

2015-06-10clk: exynos5433: Add CLK_SET_RATE_PARENT to support DVFS for big.LITTLE coreChanwoo Choi1-14/+12
This patch adds CLK_SET_RATE_PARENT flag to support DVFS of Cortex-{A53|A57} core (big.LITTLE core) because 'sclk_{apollo|atlas}' leaf clock is used to change the CPU frequency of Cortex-{A53|A57} core in arm_big_little.c driver. - 'apollo' word means the LITTLE core (Cortex-A53 core) in Exynos5433 TRM. - 'atlas' word means the big core (Cortex-A57 core) in Exynos5433 TRM.
