Subject: [PATCH v3 00/10] clk: samsung: exynos5433: Fix bug and support
 dvfs/suspend-to-ram

This patchset fix the bug and support the DVFS/Suspend-to-RAM. And This patchset
remove the CONFIG_ARCH_EXYNOS5433 insteadf use the CONFIG_ARCH_EXYNOS because
Arnd Bergmann gave me a comment[1] that don't add specific CONFIG_ARCH_EXYNOS5433
for ARM-64bit SoC. And this patchset fix following bugs:
[1] https://lkml.org/lkml/2015/2/26/102

Detailed descirption of each patch:
1. Fix the bug
- Fix wrong offset of PCLK_MSCL_SECURE_SMMU_JPEG in CMU_MSCL. (patch2)
- Fix wrong register for ENABLE_PCLK_MIF_SECURE_MONOTONIC_CNT (patch3)
- Fix wrong parent clock of 'sclk_apollo' clock. (patch4)
- Fix wrong PMS value for 700MHz. (patch5)

2. Support the DVFS for big.LITTLE cores and GPU
- Add CLK_SET_RATE_PARENT flags to propagate parent clock
  when changing the clock for DVFS(big.LITTLE Cores and GPU) (patch6/8)

3. Support the suspend-to-ram
- Add missing DIV_CPIF register to save/restore register on suspend-to-ram (patch7)
- Add CLK_IGNORE_UNUSED flag to SMC (Secure Monitor Call) cloks to support
  the suspend-to-ram (patch9)
- Add CLK_IGNORE_UNUSED flag some clocks to support the suspend-to-ram (patch10)

Changelog:
Change fromv v2:
(https://lkml.org/lkml/2015/4/2/824)
- Add new patches (patch7 ~ patch10)

Change from v1:
(https://lkml.org/lkml/2015/3/17/855)
- Add new patches (patch3 ~ patch6)
