I did fix up the small ordering issues already but then found the i2s
pinctrl issue below, which will need a slightly bigger change and thus
a respin please.

odering and a bit of spacing:

+ i2s0_sound {
+ compatible = "simple-audio-card";
+ simple-audio-card,format = "i2s";
+ simple-audio-card,name = "Haikou,I2S-codec";
+ simple-audio-card,mclk-fs = <512>;
+
+ simple-audio-card,codec {
+ clocks = <&sgtl5000_clk>;
+ sound-dai = <&sgtl5000>;
+ };
+
+ simple-audio-card,cpu {
+ bitclock-master;
+ frame-master;
+ sound-dai = <&i2s0>;
+ };
+ };

ordering again

ordering

+&i2s0 {

+ rockchip,playback-channels = <2>;
+ rockchip,capture-channels = <2>;
+ #sound-dai-cells = <0>;

node names should use dashes, so
i2s0_2ch_bus: i2s0-2ch-bus

But also, could you define the generic i2s0-2ch-bus (incl the phandle)
in rk3399.dtsi in a first patch and just override it here to not use that
LRCK_RX pin please?


Thanks
