1* mvebu (Kirkwood, Dove, Armada 370) audio controller
2
3Required properties:
4
5- compatible:
6  "marvell,kirkwood-audio" for Kirkwood platforms
7  "marvell,dove-audio" for Dove platforms
8  "marvell,armada370-audio" for Armada 370 platforms
9  "marvell,armada-380-audio" for Armada 38x platforms
10
11- reg: physical base address of the controller and length of memory mapped
12  region (named "i2s_regs").
13  With "marvell,armada-380-audio" two other regions are required:
14  first of those is dedicated for Audio PLL Configuration registers
15  (named "pll_regs") and the second one ("soc_ctrl") - for register
16  where one of exceptive I/O types (I2S or S/PDIF) is set.
17
18- interrupts:
19  with "marvell,kirkwood-audio", the audio interrupt
20  with "marvell,dove-audio", a list of two interrupts, the first for
21  the data flow, and the second for errors.
22
23- clocks: one or two phandles.
24  The first one is mandatory and defines the internal clock.
25  The second one is optional and defines an external clock.
26
27- clock-names: names associated to the clocks:
28	"internal" for the internal clock
29	"extclk" for the external clock
30
31Optional properties:
32
33- spdif-mode:
34  Enable S/PDIF mode on Armada 38x SoC. Using this property
35  disables standard I2S I/O. Valid only with "marvell,armada-380-audio"
36  compatible string.

41	compatible = "marvell,dove-audio";
42	reg = <0xb4000 0x2210>;
43	interrupts = <21>, <22>;
44	clocks = <&gate_clk 13>;
45	clock-names = "internal";
