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> +--- + arch/arm64/boot/dts/renesas/r8a7795.dtsi | 10 +++++----- + arch/arm64/boot/dts/renesas/r8a7796.dtsi | 10 +++++----- + 2 files changed, 10 insertions(+), 10 deletions(-) + +diff --git a/arch/arm64/boot/dts/renesas/r8a7795.dtsi b/arch/arm64/boot/dts/renesas/r8a7795.dtsi +index f7f947d27b0d..5bcc2391587d 100644 +--- a/arch/arm64/boot/dts/renesas/r8a7795.dtsi ++++ b/arch/arm64/boot/dts/renesas/r8a7795.dtsi +@@ -3054,11 +3054,6 @@ + #address-cells = <1>; + #size-cells = <0>; + +- port@0 { +- reg = <0>; +- du_out_rgb: endpoint { +- }; +- }; + port@1 { + reg = <1>; + du_out_hdmi0: endpoint { +@@ -3076,6 +3071,11 @@ + du_out_lvds0: endpoint { + }; + }; ++ port@0 { ++ reg = <0>; ++ du_out_rgb: endpoint { ++ }; ++ }; + }; + }; + +diff --git a/arch/arm64/boot/dts/renesas/r8a7796.dtsi b/arch/arm64/boot/dts/renesas/r8a7796.dtsi +index df26656e0f19..154ac1dd91fa 100644 +--- a/arch/arm64/boot/dts/renesas/r8a7796.dtsi ++++ b/arch/arm64/boot/dts/renesas/r8a7796.dtsi +@@ -2846,11 +2846,6 @@ + #address-cells = <1>; + #size-cells = <0>; + +- port@0 { +- reg = <0>; +- du_out_rgb: endpoint { +- }; +- }; + port@1 { + reg = <1>; + du_out_hdmi0: endpoint { +@@ -2862,6 +2857,11 @@ + du_out_lvds0: endpoint { + }; + }; ++ port@0 { ++ reg = <0>; ++ du_out_rgb: endpoint { ++ }; ++ }; + }; + }; + +-- +2.11.0 + |
