dt-bindings: sound: Convert Allwinner SPDIF binding to YAML The Allwinner SoCs feature an SPDIF controller across multiple SoC generations. However, earlier generations were a bit simpler than the subsequent ones, and for example would always have RX and TX capabilities, and no reset lines. In order to express this, let's create two YAML schemas instead of the free form text we had before.

dt-bindings: sound: sun4i-spdif: Add Allwinner H6 compatible Allwinner H6 has a SPDIF controller with an increase of the fifo size and a sligher difference in memory mapping compare to H3/A64. This make it not compatible with the previous generation. Introduce a specific bindings for H6 SoC.

dt-bindings: sound: sun4i-spdif: Document that the RX channel can be missing The H3 and compatibles controllers don't have any reception capabilities, even though it was never documented as such in the binding before. Therefore, on those controllers, we don't have the option to set an RX DMA channel. This was already done in the DTSI, but the binding itself was never updated. Let's add a special case in the schemas. Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com> Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Mark Brown <broonie@kernel.org>
