|
||
|
|
|
||
|
|
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:
|
||

|
|
Example:
|
||
|
|
|
||
|
|
i2s1: audio-controller@b4000 {
|
||
|
|
compatible = "marvell,dove-audio";
|
||
|
|
reg = <0xb4000 0x2210>;
|
||
|
|
interrupts = <21>, <22>;
|
||
|
|
clocks = <&gate_clk 13>;
|
||
|
|
clock-names = "internal";
