Subject: [PATCH 0/8] media: i2c: adv748x: add support for HDMI audio

This adds minimal support for controlling the audio output I2S port available
on ADV7481 and ADV7482 HDMI decoder devices by ADI. The port carries audio
signal from the decoded HDMI stream.

An ADV7482 on the Renesas Salvator-X ES1.1 was used during development of this
code.

Alex Riesen (8):
  media: adv748x: add a device-specific wrapper for register block read
  media: adv748x: add audio mute control and output selection ioctls
  media: adv748x: add log_status ioctl
  media: adv748x: reserve space for the audio (I2S) port in the driver
    structures
  media: adv748x: add an ASoC DAI definition to the driver
  media: adv748x: reduce amount of code for bitwise modification of
    device registers
  dt-bindings: adv748x: add information about serial audio interface
    (I2S/TDM)
  arm64: dts: renesas: salvator: add a connection from adv748x codec
    (HDMI input) to the R-Car SoC
