1Texas Instruments McASP controller 2 3Required properties: 4- compatible : 5 "ti,dm646x-mcasp-audio" : for DM646x platforms 6 "ti,da830-mcasp-audio" : for both DA830 & DA850 platforms 7 "ti,omap2-mcasp-audio" : for OMAP2 platforms (TI81xx, AM33xx) 8 9- reg : Should contain McASP registers offset and length 10- interrupts : Interrupt number for McASP 11- op-mode : I2S/DIT ops mode. 12- tdm-slots : Slots for TDM operation. 13- num-serializer : Serializers used by McASP. 14- serial-dir : A list of serializer pin mode. The list number should be equal 15 to "num-serializer" parameter. Each entry is a number indication 16 serializer pin direction.
