Jayesh Choudhary Add device tree overlay to enable analog audio support on J721S2-EVM using PCM3168A codec connected to McASP4 serializers. - Add audio_refclk1 clock node to k3-j721s2-main.dtsi - Add nodes for sound-card, audio codec, I2C3 and McASP4 - Add pinmux for I2C3, McASP4, AUDIO_EXT_REFCLK1 and WKUP_GPIO_0 - Add GPIO expander (TCA6408) for codec control - Add gpio-mux controller to route I2C3 lines - Add GPIO hogs to route McASP serializers - Set idle-state to 0 in mux0 and mux1 for McASP signal routing - Disable main_mcan3 and main_mcan5 as they conflict with McASP4 signal routing via mux0 and mux1 Co-developed-by: Moteen Shah Signed-off-by: Jayesh Choudhary Signed-off-by: Moteen Shah Reviewed-by: Hari Prasath Gujulan Elango Reviewed-by: Sen Wang ---
