Texas Instruments McASP controller
Required properties:
compatible :
“ti,dm646x-mcasp-audio” : for DM646x platforms
“ti,da830-mcasp-audio” : for both DA830 & DA850 platforms
“ti,omap2-mcasp-audio” : for OMAP2 platforms (TI81xx, AM33xx)reg : Should contain McASP registers offset and length
interrupts : Interrupt number for McASP
op-mode : I2S/DIT ops mode.
tdm-slots : Slots for TDM operation.
num-serializer : Serializers used by McASP.
serial-dir : A list of serializer pin mode. The list number should be equal
to "num-serializer" parameter. Each entry is a number indication serializer pin direction. (0 - INACTIVE, 1 - TX, 2 - RX)
Optional properties:
- ti,hwmods : Must be “mcasp
“, n is controller instance starting 0 - tx-num-evt : FIFO levels.
- rx-num-evt : FIFO levels.
- sram-size-playback : size of sram to be allocated during playback
- sram-size-capture : size of sram to be allocated during capture
