| 2 | |
| 3 | Required properties: |
| 4 | - compatible: Should be "brcm,bcm63xx-i2s". |
| 5 | - #address-cells: 32bit valued, 1 cell. |
| 6 | - #size-cells: 32bit valued, 0 cell. |
| 7 | - reg: Should contain audio registers location and length |
| 8 | - interrupts: Should contain the interrupt for the controller. |
| 9 | - clocks: Must contain an entry for each entry in clock-names. |
| 10 | Please refer to clock-bindings.txt. |
| 11 | - clock-names: One of each entry matching the clocks phandles list: |
| 12 | - "i2sclk" (generated clock) Required. |
| 13 | - "i2sosc" (fixed 200MHz clock) Required. |
| 14 | |
| 15 | (1) : The generated clock is required only when any of TX and RX |
| 16 | works on Master Mode. |
| 17 | (2) : The fixed 200MHz clock is from internal chip and always on |
| 18 | |
| 19 | Example: |
| 20 | |
| 21 | i2s: bcm63xx-i2s { |
| 22 | #address-cells = <1>; |
| 23 | #size-cells = <0>; |
| 24 | compatible = "brcm,bcm63xx-i2s"; |
| 25 | reg = <0xFF802080 0xFF>; |
| 26 | interrupts = <GIC_SPI 84 IRQ_TYPE_LEVEL_HIGH>; |
| 27 | clocks = <&i2sclk>, <&osc>; |
| 28 | clock-names = "i2sclk","i2sosc"; |
| 29 | }; |
