[PATCH v2 0/3] arm64: dts: meson-axg: add audio support

[PATCH v2 0/3] arm64: dts: meson-axg: add audio support

[Jerome Brunet]

The main purpose of this patchset is to add the audio devices on amlogic's
AXG SoCs.

In term of dependency, apart from the clock bindings you have already
pulled for your second PR to arm-soc, this patchset requires the ARB
reset bindings [0] for patch 1.

Changes since v1 [1]:
 - Dropped applied changes
 - Update card bindings following Rob's comments on the card DT binding
   documentation.

[0]: 3bfd2fe0ab49 ("reset: meson: add dt-bindings for meson-axg audio arb")
[1]: https://lkml.kernel.org/r/20180724125238.14567-1-jbrunet at baylibre.com

[PATCH v2 1/3] arm64: dts: meson-axg: add audio fifos

[Jerome Brunet]

Add TODDR and FRDDR audio fifos of the AXG SoC.
These fifos are the capture and playback memory interfaces of audio
subsystem of the AXG.

[PATCH v2 3/3] arm64: dts: meson-axg: s400: add sound card

[Jerome Brunet]

Add the sound card of the s400. With it the following interface
should be working:
 * Lineout
 * Daugther card speaker 1 (same output as lineout)
 * Linein
 * SPDIF output
