5 "ti,dm646x-mcasp-audio" : for DM646x platforms
6 "ti,da830-mcasp-audio" : for both DA830 & DA850 platforms
7 "ti,am33xx-mcasp-audio" : for AM33xx platforms (AM33xx, TI81xx)
9 - reg : Should contain reg specifiers for the entries in the reg-names property.
10 - reg-names : Should contain:
11 * "mpu" for the main registers (required). For compatibility with
12 existing software, it is recommended this is the first entry.
13 * "dat" for separate data port register access (optional).
14 - op-mode : I2S/DIT ops mode. 0 for I2S mode. 1 for DIT mode used for S/PDIF,
15 IEC60958-1, and AES-3 formats.
16 - tdm-slots : Slots for TDM operation. Indicates number of channels transmitted
17 or received over one serializer.
18 - serial-dir : A list of serializer configuration. Each entry is a number
19 indication for serializer pin direction.
20 (0 - INACTIVE, 1 - TX, 2 - RX)
21 - dmas: two element list of DMA controller phandles and DMA request line
23 - dma-names: identifier string for each DMA request line in the dmas property.
24 These strings correspond 1:1 with the ordered pairs in dmas. The dma
25 identifiers must be "rx" and "tx".
29 - ti,hwmods : Must be "mcasp<n>", n is controller instance starting 0
30 - tx-num-evt : FIFO levels.
31 - rx-num-evt : FIFO levels.
32 - sram-size-playback : size of sram to be allocated during playback
33 - sram-size-capture : size of sram to be allocated during capture
34 - interrupts : Interrupt numbers for McASP, currently not used by the driver
35 - interrupt-names : Known interrupt names are "tx" and "rx"
36 - pinctrl-0: Should specify pin control group used for this controller.
37 - pinctrl-names: Should contain only one value - "default", for more details
