Please refer to clock-bindings.txt. - clock-names: One of each entry matching the clocks phandles list: - "i2sclk" (generated clock) Required. - "i2sosc" (fixed 200MHz clock) Required. (1) : The generated clock is required only when any of TX and RX works on Master Mode. (2) : The fixed 200MHz clock is from internal chip and always on Example: i2s: bcm63xx-i2s { #address-cells = <1>; #size-cells = <0>; compatible = "brcm,bcm63xx-i2s"; reg = <0xFF802080 0xFF>; interrupts = <GIC_SPI 84 IRQ_TYPE_LEVEL_HIGH>; clocks = <&i2sclk>, <&osc>; clock-names = "i2sclk","i2sosc"; }; |
