1 | * Freescale MXS Serial Audio Interface (SAIF) |
| 2 | ||
| 3 | Required properties: | |
| 4 | - compatible: Should be "fsl,<chip>-saif" | |
| 5 | - reg: Should contain registers location and length | |
| 62477adf SG |
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 | |
| 12 | Optional properties: | |
| 13 | - fsl,saif-master: phandle to the master SAIF. It's only required for | |
| 14 | the slave SAIF. | |
| 15 | ||
| 16 | Note: Each SAIF controller should have an alias correctly numbered | |
| 17 | in "aliases" node. | |
| 18 | ||
| 19 | Example: | |
| 20 | ||
| 21 | aliases { | |
| 22 | saif0 = &saif0; | |
| 23 | saif1 = &saif1; | |
| 24 | }; | |
| 25 | ||
| 26 | saif0: saif@80042000 { | |
| 27 | compatible = "fsl,imx28-saif"; | |
| 28 | reg = <0x80042000 2000>; | |
| 62477adf SG |
29 | interrupts = <59>; |
| 30 | dmas = <&dma_apbx 4>; | |
| 31 | dma-names = "rx-tx"; | |
| 08641c7c SG |
