From 573b03317aab3529bd813ef5259cd84c98edb52d Mon Sep 17 00:00:00 2001 From: Ye Li Date: Thu, 18 Jun 2026 09:19:36 +0800 Subject: arm: dts: imx943-evk: Add label for gpio expander devices Because the i2c address of some gpio expander devices are same, so in dts they have same node name which lead to same gpio device name. Users can't get the GPIO through GPIO API or GPIO command. Add the label to each gpio expander node, hence give unique name.
