| 2 | |
| 3 | Required properties: |
| 4 | - compatible : |
| 5 | "ti,dm646x-mcasp-audio" : for DM646x platforms |
| 6 | "ti,da830-mcasp-audio" : for both DA830 & DA850 platforms |
| 7 | |
| 8 | - reg : Should contain McASP registers offset and length |
| 9 | - interrupts : Interrupt number for McASP |
| 10 | - op-mode : I2S/DIT ops mode. |
| 11 | - tdm-slots : Slots for TDM operation. |
| 12 | - num-serializer : Serializers used by McASP. |
| 13 | - serial-dir : A list of serializer pin mode. The list number should be equal |
| 14 | to "num-serializer" parameter. Each entry is a number indication |
| 15 | serializer pin direction. (0 - INACTIVE, 1 - TX, 2 - RX) |
| 16 | |
| 17 | |
| 18 | Optional properties: |
| 19 | |
| 20 | - ti,hwmods : Must be "mcasp<n>", n is controller instance starting 0 |
| 21 | - tx-num-evt : FIFO levels. |
| 22 | - rx-num-evt : FIFO levels. |
| 23 | - sram-size-playback : size of sram to be allocated during playback |
| 24 | - sram-size-capture : size of sram to be allocated during capture |
| 25 | |
