Provide an overlay that enables the panel. Signed-off-by: Frieder Schrempf --- Note: This currently throws the following warnings: Warning (graph_port): /fragment@3: graph port node name should be 'port' Warning (graph_endpoint): /fragment@3/__overlay__: graph endpoint node name should be 'endpoint' Warning (graph_endpoint): /fragment@3/__overlay__: graph connection to node '/fragment@7/__overlay__/ports/port@0/endpoint' is not bidirectional There is the following commit in DTC that relaxes these checks and will eventually resolve these warnings: 84b056a89d ("checks: relax graph checks for overlays") https://git.kernel.org/pub/scm/utils/dtc/dtc.git/commit/?id=84b056a89d3c5b6cf6c5eeeafd4c4b14d6333aa9 --- arch/arm64/boot/dts/freescale/Makefile | 4 + .../boot/dts/freescale/imx8mm-kontron-dl.dtso | 210 ++++++++++++++++++ 2 files changed, 214 insertions(+) create mode 100644 arch/arm64/boot/dts/freescale/imx8mm-kontron-dl.dtso diff --git a/arch/arm64/boot/dts/freescale/Makefile b/arch/arm64/boot/dts/freescale/Makefile index f04c22b7de72e..d8af069139920 100644 --- a/arch/arm64/boot/dts/freescale/Makefile +++ b/arch/arm64/boot/dts/freescale/Makefile @@ -244,6 +244,10 @@ dtb-$(CONFIG_ARCH_MXC) += imx93-tqma9352-mba93xxla.dtb dtb-$(CONFIG_ARCH_MXC) += imx93-var-som-symphony.dtb dtb-$(CONFIG_ARCH_MXC) += imx95-19x19-evk.dtb +imx8mm-kontron-dl-dtbs := imx8mm-kontron-bl.dtb imx8mm-kontron-dl.dtbo + +dtb-$(CONFIG_ARCH_MXC) += imx8mm-kontron-dl.dtb + imx8mm-venice-gw72xx-0x-imx219-dtbs := imx8mm-venice-gw72xx-0x.dtb imx8mm-venice-gw72xx-0x-imx219.dtbo imx8mm-venice-gw72xx-0x-rpidsi-dtbs := imx8mm-venice-gw72xx-0x.dtb imx8mm-venice-gw72xx-0x-rpidsi.dtbo imx8mm-venice-gw72xx-0x-rs232-rts-dtbs := imx8mm-venice-gw72xx-0x.dtb imx8mm-venice-gw72xx-0x-rs232-rts.dtbo diff --git a/arch/arm64/boot/dts/freescale/imx8mm-kontron-dl.dtso b/arch/arm64/boot/dts/freescale/imx8mm-kontron-dl.dtso new file mode 100644 index 0000000000000..b2d593d700e2d --- /dev/null +++ b/arch/arm64/boot/dts/freescale/imx8mm-kontron-dl.dtso @@ -0,0 +1,210 @@ +// SPDX-License-Identifier: GPL-2.0 +/* + * Copyright (C) 2023 Kontron Electronics GmbH + */ + +/dts-v1/;
