* 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";
};
