From 38e7f9092efbbf2a4a67e4410b55b797f8d1e184 Mon Sep 17 00:00:00 2001 From: Siddharth Vadapalli s-vadapalli@ti.com Date: Fri, 28 Feb 2025 11:08:50 +0530 Subject: [PATCH] arm64: dts: ti: k3-j784s4-j742s2-main-common: Fix serdes_ln_ctrl reg-masks

Commit under Fixes added the 'idle-states' property for SERDES4 lane muxes without defining the corresponding register offsets and masks for it in the 'mux-reg-masks' property within the 'serdes_ln_ctrl' node.

Fix this.
