[PATCH v4 4/7] ASoC: sun4i-spdif: Add support for H6 SoC

Clément Péron
2019-05-27T20:10:26Z

Allwinner H6 has a different mapping for the fifo register controller.

Actually only the fifo TX bit is used in the drivers.

Use the freshly introduced quirks to make this drivers compatible with
the Allwinner H6.
