Merge tag 'clk-v4.14-samsung' of git://git.kernel.org/pub/scm/linux/kernel/git/snawrocki/clk into clk-next
Pull Samsung clk driver updates from Sylwester Nawrocki:
Changes in definitions of audio related clocks for Exynos5420/5422/5800
SoCs: a fix of mau_epll clock definition and changes enabling clock rate
setting propagation on a path from the I2S IP block up the EPLL.
* tag 'clk-v4.14-samsung' of git://git.kernel.org/pub/scm/linux/kernel/git/snawrocki/clk:
clk: samsung: exynos542x: Enable clock rate propagation up to the EPLL
clk: samsung: Add CLK_SET_RATE_PARENT to some AUDSS CLK CON clocks
clk: samsung: Fix mau_epll clock definition for exynos5422
