Subject: [PATCH 0/9] ASoC: meson: gx: add audio output support

This patchset adds support for the i2s and spdif audio outputs of the
amlogic GX SoC family, such the S905, S905X/D, S912 and S805X. These SoCs
are used by a fair amount of boards actively maintained upstream.

This was tested on:
 * amlogic s912 q200
 * libretech s805x-ac (frite)
 * libretech s905x-cc (potato)
 * libretech s905d-pc (tartiflette)

This could also possibly support meson8 32bits SoCs but I have not tested
it myself and it could require some further tweaks.

The audio subsystem found on these SoCs has now been dropped in the newer
designs. All recent SoCs families (like g12a and sm1) derive from the AXG
audio architecture.

Jerome Brunet (9):
  ASoC: core: allow a dt node to provide several components
  ASoC: meson: g12a: extract codec-to-codec utils
  ASoC: meson: aiu: add audio output dt-bindings
  ASoC: meson: aiu: add i2s and spdif support
  ASoC: meson: aiu: add hdmi codec control support
  ASoC: meson: aiu: add internal dac codec control support
  ASoC: meson: axg: extract sound card utils
  ASoC: meson: gx: add sound card dt-binding documentation
  ASoC: meson: gx: add sound card support
