linux-renesas: preserve M3ULCB uHDMI connector name as HDMI-A-1
Booting with a KF dtb results in the uHDMI connector being moved
to HDMI-A-2 which breaks a common weston.ini shared by both SK
and SK+KF dtbs. Add support for uHDMI being fixed as HDMI-A-1.
The KF HDMI output is not HDMI-A-2.

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> +--- + arch/arm64/boot/dts/renesas/r8a7796.dtsi | 10 +++++----- + 1 file changed, 5 insertions(+), 5 deletions(-) + +diff --git a/arch/arm64/boot/dts/renesas/r8a7796.dtsi b/arch/arm64/boot/dts/renesas/r8a7796.dtsi +index bf37b8aa0e2f..e3a5c25bc3da 100644 +--- a/arch/arm64/boot/dts/renesas/r8a7796.dtsi ++++ b/arch/arm64/boot/dts/renesas/r8a7796.dtsi +@@ -2391,11 +2391,6 @@ + #address-cells = <1>; + #size-cells = <0>; + +- port@0 { +- reg = <0>; +- du_out_rgb: endpoint { +- }; +- }; + port@1 { + reg = <1>; + du_out_hdmi0: endpoint { +@@ -2406,6 +2401,11 @@ + du_out_lvds0: endpoint { + }; + }; ++ port@0 { ++ reg = <0>; ++ du_out_rgb: endpoint { ++ }; ++ }; + }; + }; + +-- +2.11.0 + diff --git a/meta-rcar-gen3-adas/recipes-kernel/linux/linux-renesas_4.9.bbappend b/meta-rcar-gen3-adas/recipes-kernel/linux/linux-renesas_4.9.bbappend index 88f17eb..924e309 100644 --- a/meta-rcar-gen3-adas/recipes-kernel/linux/linux-renesas_4.9.bbappend +++ b/meta-rcar-gen3-adas/recipes-kernel/linux/linux-renesas_4.9.bbappend @@ -80,6 +80,7 @@ SRC_URI_append = " \ file://0079-Revert-dmaengine-rcar-dmac-use-TCRB-instead-of-TCR-f.patch \ file://0080-dmaengine-rcar-dmac-ensure-CHCR-DE-bit-is-actually-0.patch \ file://0081-dmaengine-rcar-dmac-use-TCRB-instead-of-TCR-for-resi.patch \ + file://0001-arm64-dts-renesas-preserve-drm-HDMI-connector-naming.patch \ " SRC_URI_append_r8a7797 = " \ |
