Hi Javesh,

Convert the bindings for McASP controllers for TI SOCs from txt
to YAML schema.

Adds additional properties 'clocks', 'clock-names', 'power-domains',
'#sound-dai-cells' and 'port' which were missing from the txt file.
Removes properties 'sram-size-playback' and 'sram-size-capture'
since they are not used.
Adds 'dmas' and 'dma-names' in the example which were missing from
the txt file.
Changes 'interrupts' and 'interrupt-names' from optional to
required properties.
Changes 'op-modes', 'serial-dir' to optional properties as they are
not needed if the McASP is used only as GPIO.
Changes 'tdm-slots' to required property only for I2S operation mode.

Adds the yaml file in the 'MAINTAINERS' under the heading 'TEXAS
INSTRUMENTS ASoC DRIVERS'

I would have added description for the GPIO support as it is not obvious
that 2 is going to be for AXR2 or 29 is for ACLKR pin.
But I don't think this functionality is going to be used apart from the
one dra7 evm.

Thank you for the updates and the nice work!

+properties:
+ compatible:
+ enum:
+ - ti,dm646x-mcasp-audio
+ - ti,da830-mcasp-audio
+ - ti,am33xx-mcasp-audio
+ - ti,dra7-mcasp-audio
+ - ti,omap4-mcasp-audio

This is the only thing which bugs me: the pointless '-audio' postfix for
the compatible string...


Removing the postfix would also require a lot of dts changes which might be backward incompatible. So it is probably not a good idea.
Should we still consider this?
