+Subject: [PATCH] arm64: dts: renesas: disable r8a7796 hscif0 dma
+
+When streaming A2DP audio on WiLink8, DMA errors are
+seen from the rcar-dmac driver servicing hscif0. As
+a result, data corruption is seen by the UIM service
+managing the link to the Wilink8 device. This data
+corruption manifests as dropped frames and audibly as
+"skips" in the audio playback.
+
+Workaround this issue by disabling DMA for hscif0.
+
+Signed-off-by: Matt Porter <mporter@konsulko.com>
