In the SN65DSI86 DSI-2-eDP bridge, HPD is not supported as of now. But DisplayPort connector_type usecases does need hpd to be enabled. In order not to break any platform from those driver changes, add "no-hpd" property to all the existing sn65dsi86 nodes (that don't have it already) as hpd is not being used there anyways. Signed-off-by: Jayesh Choudhary <j-choudhary@ti.com> --- Upcoming driver changes that will break platforms if we do not have this property in all the existing sn65dsi86 nodes that assumes hpd is disabled: <https://lore.kernel.org/all/20250529110418.481756-1-j-choudhary@ti.com/> (sc7180-trogdor-ti-sn65dsi86.dtsi, sdm850-lenovo-yoga-c630.dts and sdm845-cheza.dtsi already have this property.) NOTE: Grouping the logical changes together in a single patch even though we have multiple vendor dts. I hope that is not an issue. .../boot/dts/amlogic/meson-g12b-bananapi-cm4-mnt-reform2.dts | 1 + arch/arm64/boot/dts/freescale/imx8mq-mnt-reform2.dts | 1 + arch/arm64/boot/dts/qcom/sc7180-acer-aspire1.dts | 1 + arch/arm64/boot/dts/renesas/r8a779a0-falcon-cpu.dtsi | 1 + arch/arm64/boot/dts/renesas/r8a779g3-sparrow-hawk.dts | 1 + arch/arm64/boot/dts/renesas/r8a779h0-gray-hawk-single.dts | 1 + arch/arm64/boot/dts/renesas/white-hawk-cpu-common.dtsi | 1 + 7 files changed, 7 insertions(+)
