[alsa-devel] [PATCH 0/2] ASoC: rockchip: i2s: add support for grabbing output clock to codec

[Jianqun Xu]

Reference to Chapter 3 Clock & Reset Unit (CRU) of RK3288 TRM, i2s0_clkout has
two source clock, XIN24M_DIV2 for 12M and clk_i2s0 for more kinds of
frequencies, I2S0(i2s_clk) has only single source clock clk_i2s0.

i2s0_clkout: generate to output to outside of chip, generally for codec
I2S0(i2s_clk): generate for i2s controller inside of chip

Jianqun Xu (2):
  ASoC: rockchip-i2s: dt: add i2s_clkout to list of clocks
  ASoC: rockchip: i2s: add support for grabbing output clock to codec
