+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>", 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
+
+Example:
+
+mcasp0: mcasp0@1d00000 {
+       compatible = "ti,da830-mcasp-audio";
