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. Fixes: 7287d423f138 ("arm64: dts: ti: k3-j784s4-main: Add system controller and SERDES lane mux") Cc: stable@vger.kernel.org Signed-off-by: Siddharth Vadapalli <s-vadapalli@ti.com> --- Patch is based on commit 76544811c850 Merge tag 'drm-fixes-2025-02-28' of https://gitlab.freedesktop.org/drm/kernel of the master branch of Mainline Linux. v1: https://patchwork.kernel.org/project/linux-arm-kernel/patch/20250227061643.144026-1-s-vadapalli@ti.com/ Changes since v1: - Updated offsets to begin from 0x40 instead of 0x30. This is because SERDES3 is not present in J784S4. Regards, Siddharth. arch/arm64/boot/dts/ti/k3-j784s4-j742s2-main-common.dtsi | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-)
