The bare ULCB SK has only an HDMI encoder +in use on port 1. When the system is booted with an SK +dtb, port 1's HDMI encoder is assigned as HDMI-A-1 because +it is the first (and only) encoder present. When booting +a KF dtb, port 0's HDMI encoder preceeds port1 in the dtb due +to incremental ordering of the endpoint port nodes. This causes +the KF HDMI to be assigned HDMI-A-1 and the SK HDMI to be assigned +as HDMI-A-2. In order to preserve the SK's HDMI output naming as +connector HDMI-A-1, reorder the endpoint port nodes so that port1 +is first. + +Change-Id: Ibbb1975c2383a526a54c257fb7d68d32a042d468 +Signed-off-by: Matt Porter <mporter@konsulko.com> +Signed-off-by: Ronan Le Martret <ronan.lemartret@iot.bzh> +Signed-off-by: Harunobu Kurokawa <harunobu.kurokawa.dn@renesas.com> +--- + arch/arm64/boot/dts/renesas/r8a77951.dtsi | 10 +++++----- + arch/arm64/boot/dts/renesas/r8a77960.dtsi | 10 +++++----- + arch/arm64/boot/dts/renesas/r8a77961.dtsi | 10 +++++----- + 3 files changed, 15 insertions(+), 15 deletions(-) + +diff --git a/arch/arm64/boot/dts/renesas/r8a77951.dtsi b/arch/arm64/boot/dts/renesas/r8a77951.dtsi +index 12e78097533e..9ead58e8a7c2 100644 +--- a/arch/arm64/boot/dts/renesas/r8a77951.dtsi ++++ b/arch/arm64/boot/dts/renesas/r8a77951.dtsi +@@ -3943,11 +3943,6 @@ ports { + #address-cells = <1>; + #size-cells = <0>; + +- port@0 { +- reg = <0>; +- du_out_rgb: endpoint { +- }; +- }; + port@1 { + reg = <1>; + du_out_hdmi0: endpoint { +@@ -3966,6 +3961,11 @@ du_out_lvds0: endpoint { + remote-endpoint = <&lvds0_in>; + }; + }; ++ port@0 { ++ reg = <0>; ++ du_out_rgb: endpoint { ++ }; ++ }; + }; + }; + +diff --git a/arch/arm64/boot/dts/renesas/r8a77960.dtsi b/arch/arm64/boot/dts/renesas/r8a77960.dtsi +index 66ab48b3a704..a5481dc4a3f1 100644 +--- a/arch/arm64/boot/dts/renesas/r8a77960.dtsi ++++ b/arch/arm64/boot/dts/renesas/r8a77960.dtsi +@@ -3628,11 +3628,6 @@ ports { + #address-cells = <1>; + #size-cells = <0>; + +- port@0 { +- reg = <0>; +- du_out_rgb: endpoint { +- }; +- }; + port@1 { + reg = <1>; + du_out_hdmi0: endpoint { +@@ -3645,6 +3640,11 @@ du_out_lvds0: endpoint { + remote-endpoint = <&lvds0_in>; + }; + }; ++ port@0 { ++ reg = <0>; ++ du_out_rgb: endpoint { ++ }; ++ }; + }; + }; + +diff --git a/arch/arm64/boot/dts/renesas/r8a77961.dtsi b/arch/arm64/boot/dts/renesas/r8a77961.dtsi +index ef2cb77f3c32..032ef1ca0633 100644 +--- a/arch/arm64/boot/dts/renesas/r8a77961.dtsi ++++ b/arch/arm64/boot/dts/renesas/r8a77961.dtsi +@@ -3434,11 +3434,6 @@ ports { + #address-cells = <1>; + #size-cells = <0>; + +- port@0 { +- reg = <0>; +- du_out_rgb: endpoint { +- }; +- }; + port@1 { + reg = <1>; + du_out_hdmi0: endpoint { +@@ -3451,6 +3446,11 @@ du_out_lvds0: endpoint { + remote-endpoint = <&lvds0_in>; + }; + }; ++ port@0 { ++ reg = <0>; ++ du_out_rgb: endpoint { ++ }; ++ }; + }; + }; + +-- +2.25.1 + |
