Subject: [PATCH v2 01/13] ASoC: dt-bindings: davinci-mcbsp: convert McBSP bindings to yaml schema
Convert the binding for McBSP controllers for TI SoCs from txt
to YAML schema.
Add properties 'clocks', 'clock-names', 'power-domains' and
'#sound-dai-cells' which were missing from the txt file.
Add '#sound-dai-cells' and 'clocks' in the example which were missing
from the txt file.

-Texas Instruments DaVinci McBSP module
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-This binding describes the "Multi-channel Buffered Serial Port" (McBSP)
-audio interface found in some TI DaVinci processors like the OMAP-L138 or AM180x.
-
-
-Required properties:
-~~~~~~~~~~~~~~~~~~~~
-- compatible :
- "ti,da850-mcbsp" : for DA850, AM180x and OPAM-L138 platforms
-
-- reg : physical base address and length of the controller memory mapped
- region(s).
-- reg-names : Should contain:
- * "mpu" for the main registers (required).
- * "dat" for the data FIFO (optional).
-
-- dmas: three element list of DMA controller phandles, DMA request line and
- TC channel ordered triplets.
-- dma-names: identifier string for each DMA request line in the dmas property.
- These strings correspond 1:1 with the ordered pairs in dmas. The dma
- identifiers must be "rx" and "tx".
-
-Optional properties:
-~~~~~~~~~~~~~~~~~~~~
-- interrupts : Interrupt numbers for McBSP
-- interrupt-names : Known interrupt names are "rx" and "tx"
-
-- pinctrl-0: Should specify pin control group used for this controller.
-- pinctrl-names: Should contain only one value - "default", for more details
- please refer to pinctrl-bindings.txt
-
-Example (AM1808):
-~~~~~~~~~~~~~~~~~
-
-mcbsp0: mcbsp@...0000 {
- compatible = "ti,da850-mcbsp";
- pinctrl-names = "default";
- pinctrl-0 = <&mcbsp0_pins>;
-
- reg = <0x00110000 0x1000>,
- <0x00310000 0x1000>;
- reg-names = "mpu", "dat";
- interrupts = <97 98>;
- interrupt-names = "rx", "tx";
- dmas = <&edma0 3 1
- &edma0 2 1>;
- dma-names = "tx", "rx";
-};
