From 3683d4f690b83a3ec8df566aa153076bfe2eb3f4 Mon Sep 17 00:00:00 2001 From: Per Larsson Date: Mon, 20 Jul 2026 19:42:42 +0200 Subject: [PATCH] arm64: dts: allwinner: a523: Add SPDIF output PH pin mux option When SPDIF support was added for the Allwinner A523 family of SoCs, only two of the three possible pins were added to the dtsi, since the third would clash with the first ethernet port (gmac0). However, some devices don't use gmac0 and instead use gmac1 for the only available ethernet port, leaving the pin free to use for SPDIF. Add the remaining pin mux option from the PH pin group to the dtsi so such devices can (later) use it.
