I've successfully tested this series on imx8mm-venice-gw73xx-0x using the following: - DFROBOT 7" raspberrypi touchscreen display (DFR0506) [1] - the following defconfig: CONFIG_REGULATOR_RASPBERRYPI_TOUCHSCREEN_ATTINY CONFIG_DRM_PANEL_SIMPLE CONFIG_DRM_PANEL_BRIDGE CONFIG_DRM_PANEL_RASPBERRYPI_TOUCHSCREEN CONFIG_DRM_TOSHIBA_TC358762 CONFIG_DRM_SAMSUNG_DSIM CONFIG_DRM_MXSFB - the following dt overlay: // SPDX-License-Identifier: (GPL-2.0+ OR MIT) /* * Copyright 2022 Gateworks Corporation */ #include <dt-bindings/gpio/gpio.h> #include "imx8mm-pinfunc.h" /dts-v1/; /plugin/; &{/} { compatible = "gw,imx8mm-gw73xx-0x", "fsl,imx8mm"; panel { compatible = "powertip,ph800480t013-idf02"; power-supply = <&attiny>; backlight = <&attiny>; port { panel_out_bridge: endpoint { remote-endpoint = <&bridge_out_panel>; }; }; }; }; &i2c3 { #address-cells = <1>; #size-cells = <0>; attiny: regulator@45 { compatible = "raspberrypi,7inch-touchscreen-panel-regulator"; reg = <0x45>; }; }; &lcdif { status = "okay"; }; &dsi { #address-cells = <1>; #size-cells = <0>; status = "okay"; bridge@0 { compatible = "toshiba,tc358762"; reg = <0>; vddc-supply = <&attiny>; #address-cells = <1>; #size-cells = <0>; status = "okay"; ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; bridge_in_dsi: endpoint { remote-endpoint = <&dsi_out_bridge>; data-lanes = <0 1>; }; }; port@1 { reg = <1>; bridge_out_panel: endpoint { remote-endpoint = <&panel_out_bridge>; }; }; }; }; ports { #address-cells = <1>; #size-cells = <0>; port@1 { reg = <1>; dsi_out_bridge: endpoint { remote-endpoint = <&bridge_in_dsi>; }; }; }; }; Tested-by: Tim Harvey <tharvey@xxxxxxxxxxxxx> #imx8mm-venice-gw73xx with DFR0506 I'll be happy to test any follow-on series as needed.
