From 1b134c9c4b555342be667f144ee714af1c3f6a9f Mon Sep 17 00:00:00 2001 From: Markus Niebel Date: Thu, 11 Sep 2014 15:56:56 +0800 Subject: ARM: DT: imx53: fix lvds channel 1 port using LVDS channel 1 on an i.MX53 leads to following error: imx-ldb 53fa8008.ldb: unable to set di0 parent clock to ldb_di1 This comes from imx_ldb_set_clock with mux = 0. Mux parameter must be "1" for reparenting di1 clock to ldb_di1. The value of the mux param comes from device tree port settings. On i.MX5, the internal two-input-multiplexer is used. Due to hardware limitations, only one port (port@[0,1]) can be used for each channel (lvds-channel@[0,1], respectively) Documentation update suggested by Philipp Zabel Signed-off-by: Markus Niebel Fixes: e05c8c9a790a ("ARM: dts: imx53: Add IPU DI ports and endpoints, move imx-drm node to dtsi") Cc: Acked-by: Philipp Zabel Signed-off-by: Shawn Guo Signed-off-by: Arnd Bergmann --- arch/arm/boot/dts/imx53.dtsi | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) (limited to 'arch/arm/boot/dts/imx53.dtsi') diff --git a/arch/arm/boot/dts/imx53.dtsi b/arch/arm/boot/dts/imx53.dtsi index c6c58c1..6b675a0 100644 --- a/arch/arm/boot/dts/imx53.dtsi +++ b/arch/arm/boot/dts/imx53.dtsi @@ -423,10 +423,14 @@ status = "disabled"; lvds-channel@0 { + #address-cells = <1>; + #size-cells = <0>; reg = <0>; status = "disabled"; - port { + port@0 { + reg = <0>; + lvds0_in: endpoint { remote-endpoint = <&ipu_di0_lvds0>; }; @@ -434,10 +438,14 @@ }; lvds-channel@1 { + #address-cells = <1>; + #size-cells = <0>; reg = <1>; status = "disabled"; - port { + port@1 { + reg = <1>; + lvds1_in: endpoint { remote-endpoint = <&ipu_di1_lvds1>; }; -- cgit v1.1
