From fd5c7bf8ddb51373a6c9456865b3af99f53642a2 Mon Sep 17 00:00:00 2001 From: =?utf8?q?J=2E=20Neusch=C3=A4fer?= Date: Thu, 11 Sep 2025 22:23:56 +0200 Subject: [PATCH] ARM: dts: allwinner: orangepi-zero-plus2: Add default audio routing MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The Orange Pi Zero Plus 2 has the same pinout[1] as the Orange Pi Zero[2] (with the possible exception of line-out left/right being swapped), and the Orange Pi Zero Interface Board is sold[3] as compatible with both of them. We can thus use the same audio routing.
