Merge tag 'clk-v4.11-samsung-2' of git://linuxtv.org/snawrocki/samsung into clk-next 

Pull Samsung clk driver updates from Sylwester Nawrocki:

 - Exporting clock IDs for Exynos5433 SoC MIPI DSI DPHY
 - Exynos PLL code updates and overall minor clean-ups

* tag 'clk-v4.11-samsung-2' of git://linuxtv.org/snawrocki/samsung:
  clk: samsung: mark s3c...._clk_sleep_init() as __init
  clk: samsung: Add enable/disable support for PLL35XX clocks
  clk: samsung: exynos5433: Correct typos in SoC name
  clk: samsung: exynos5433: Add data for 250MHz and 278MHz PLL rates
  clk: samsung: exynos5433: Add IDs for PHYCLK_MIPIDPHY0_* clocks
