Subject: [PATCH 00/13] ASoC: ti: davinci-i2s: Add features to McBSP driver

This series aims to add some features to McBSP driver.

Convert bindings from .txt to .yaml.
Add possibility to use an external clock as sample rate generator's
input.
Add handling of new formats (TDM, S24_LE, BP_FC).
Add optional properties in DT:
 - ti,enable-sync-err  : Enable the detection of unexpected frame pulses
 - ti,disable-free-run : Disable the free-running mode where McBSP drives
                         serial clocks during emulation halt
 - ti,drive-dx 	       : Outputs a chosen pattern on DX pin during
                         capture streams.

This has been tested on a platform designed off of the DAVINCI/OMAP-L138
connected to 3 daisy-chained AD7767. An external clock drives the
sample rate generator through the CLKS pin.
The hardware I have only allowed me to test acquisition side of McBSP.
It is connected to a 6 channels TDM and acts as Bit clock provider and
Frame clock consumer.
