[PATCH 2/3] clk: exynos5433: Allow audio subsystem clock rate propagation

[Sylwester Nawrocki]

CLK_SET_RATE_PARENT flag is added to definitions of clocks on a path
starting from CLK_SCLK_I2S1 up to AUD_PLL in order to allow setting
required audio root clock frequency for the I2S1 block. This is now
only done for the I2S1 block, related CMU_TOP, CMU_PERIC clock
definitions are changed.
