Refer to dma.txt and fsl-mxs-dma.txt for details. - dma-names: Must be "rx-tx". Optional properties: - fsl,saif-master: phandle to the master SAIF. It's only required for the slave SAIF. Note: Each SAIF controller should have an alias correctly numbered in "aliases" node. Example: aliases { saif0 = &saif0; saif1 = &saif1; }; saif0: saif@80042000 { compatible = "fsl,imx28-saif"; reg = <0x80042000 2000>; interrupts = <59>; dmas = <&dma_apbx 4>; dma-names = "rx-tx"; }; saif1: saif@80046000 { compatible = "fsl,imx28-saif"; reg = <0x80046000 2000>; interrupts = <58>; dmas = <&dma_apbx 5>; dma-names = "rx-tx"; fsl,saif-master = <&saif0>; }; |
