From 34f2866b3548608a636a4ab37ede8749f50782f0 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Thu, 25 Dec 2025 18:36:13 +0800 Subject: [PATCH] dt-bindings: pinctrl: sunxi: Allow pinmux sub-pattern with leading numbers The pattern for pinmux node names is typically the peripheral name and instance number, followed by pingroup name if there are multiple options. Normally the instance number is directly appended to the peripheral name, like "mmc0" or "i2c2". But if the peripheral name ends with a number, then it becomes confusing. On the A20, the PS2 interface controller has two instances. This produces pinmux node names like "ps2-0-pins". Make the sub-pattern "[0-9]-" valid to fit this pattern. Avoid having to confusing "ps20-pins" name.
