Subject: [PATCH v3 4/7] ASoC: sun4i-spdif: Add support for H6 SoC
Date:   Sat, 25 May 2019 18:23:20 +0200

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.
