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. 37 38Example: 39 40i2s1: audio-controller@b4000 { 41 compatible = "marvell,dove-audio"; 42 reg = <0xb4000 0x2210>; 43 interrupts = <21>, <22>; 44 clocks = <&gate_clk 13>; 45 clock-names = "internal"; 46}; 47
