| * mvebu (Kirkwood, Dove, Armada 370) audio controller |
| |
| Required properties: |
| |
| - compatible: |
| "marvell,kirkwood-audio" for Kirkwood platforms |
| "marvell,dove-audio" for Dove platforms |
| "marvell,armada370-audio" for Armada 370 platforms |
| "marvell,armada-380-audio" for Armada 38x platforms |
| |
| - reg: physical base address of the controller and length of memory mapped |
| region (named "i2s_regs"). |
| With "marvell,armada-380-audio" two other regions are required: |
| first of those is dedicated for Audio PLL Configuration registers |
| (named "pll_regs") and the second one ("soc_ctrl") - for register |
| where one of exceptive I/O types (I2S or S/PDIF) is set. |
| |
| - interrupts: |
| with "marvell,kirkwood-audio", the audio interrupt |
| with "marvell,dove-audio", a list of two interrupts, the first for |
| the data flow, and the second for errors. |
| |
| - clocks: one or two phandles. |
| The first one is mandatory and defines the internal clock. |
| The second one is optional and defines an external clock. |
| |
| - clock-names: names associated to the clocks: |
| "internal" for the internal clock |
| "extclk" for the external clock |
| |
| Optional properties: |
| |
| - spdif-mode: |
| Enable S/PDIF mode on Armada 38x SoC. Using this property |
| disables standard I2S I/O. Valid only with "marvell,armada-380-audio" |
| compatible string. |
| |
| Example: |
| |
| i2s1: audio-controller@b4000 { |
| compatible = "marvell,dove-audio"; |
| reg = <0xb4000 0x2210>; |
| interrupts = <21>, <22>; |
| clocks = <&gate_clk 13>; |
| clock-names = "internal"; |
| }; |
