1* Freescale MXS Serial Audio Interface (SAIF) 2 3Required properties: 4- compatible: Should be "fsl,<chip>-saif" 5- reg: Should contain registers location and length 6- interrupts: Should contain ERROR interrupt number 7- dmas: DMA specifier, consisting of a phandle to DMA controller node 8 and SAIF DMA channel ID. 9 Refer to dma.txt and fsl-mxs-dma.txt for details. 10- dma-names: Must be "rx-tx". 11 12Optional properties: 13- fsl,saif-master: phandle to the master SAIF. It's only required for 14 the slave SAIF. 15 16Note: Each SAIF controller should have an alias correctly numbered 17in "aliases" node. 18 19Example: 20 21aliases { 22 saif0 = &saif0; 23 saif1 = &saif1; 24}; 25 26saif0: saif@80042000 { 27 compatible = "fsl,imx28-saif"; 28 reg = <0x80042000 2000>; 29 interrupts = <59>; 30 dmas = <&dma_apbx 4>; 31 dma-names = "rx-tx"; 32}; 33 34saif1: saif@80046000 { 35 compatible = "fsl,imx28-saif"; 36 reg = <0x80046000 2000>; 37 interrupts = <58>; 38 dmas = <&dma_apbx 5>; 39 dma-names = "rx-tx"; 40 fsl,saif-master = <&saif0>; 41}; 42
