From 542e19c20506953c03eec57b1cb65355164dfb64 Mon Sep 17 00:00:00 2001 From: Ryan Walklin Date: Wed, 23 Oct 2024 20:56:58 +1300 Subject: [PATCH] ASoC: dt-bindings: allwinner: add H616 sun4i audio codec binding The H616 has an audio codec compatible with the sun4i-a10 driver. The codec is relatively cut down compared to some of the other Allwinner SoCs and only has a single line-out route (relying on a separate digital microphone IP block for input). HDMI and SPDIF audio are handled separately by an audio hub IP block, which is not currently implemented in mainline kernels. This requires some additional flexibility in the DMA bindings. Add compatible string and routing for the H616 audio codec, and update the required DMA descriptions.
