Clock generate unit in rockchip SoCs could generate clock named "i2s-clk-out" separate from clock named "i2s-hclk", which is for i2s controller.
Since there may not need the "i2s-clk-out" outside, we make it optional in driver, that could be decided in dts by add "i2s-clk-out" or not.
Tested on devices based on rk3288 with max98090 codec.
Jianqun Xu (1): ASoC: dt-bindings: rockchip-i2s: add an optional property "i2s_clk_out"
Sonny Rao (1): ASoC: rockchip: i2s: add support for grabbing output clock to codec
