Subject: [PATCH 0/7] Add I2S-MCC support for Microchip's SAMA7G5

SAMA7G5 includes an updated version of I2S-MCC, found previously on
SAM9X60. This controller includes 8 data pins, 4 for playback and 4 for
capture. For I2S and LEFT_J formats, these pins can be used to
send/receive up to 8 audio channels. For DSP_A, with TDM, any pins pair
(DIN/DOUT) from these 4 can be selected to send/receive data. This
version also includes 2 FIFOs (send and receive).
This patch set starts by moving the driver's bindings to yaml and
continues with adding a new compatible for the SAMA7G5 variant, followed
by the changes needed for I2S/LEFT_J support, TDM pin pair selection and
FIFO support, exclusively for SAMA7G5.

Codrin Ciubotariu (7):
  ASoC: convert Microchip I2SMCC binding to yaml
  dt-bindings: mchp,i2s-mcc: Add SAMA7G5 to binding
  ASoC: mchp-i2s-mcc: Add compatible for SAMA7G5
  ASoC: mchp-i2s-mcc: Add multi-channel support for I2S and LEFT_J
    formats
  dt-bindings: mchp,i2s-mcc: Add property to specify pin pair for TDM
  ASoC: mchp-i2s-mcc: Add support to select TDM pins
  ASoC: mchp-i2s-mcc: Add FIFOs support
