+Himax HX8369A WVGA 16.7M color TFT single chip driver with internal GRAM
+
+Himax HX8369A is a WVGA resolution driving controller.
+It is designed to provide a single chip solution that combines a source
+driver and power supply circuits to drive a TFT dot matrix LCD with
+480RGBx864 dots at the maximum.
+
+The HX8369A supports several interface modes, including MPU MIPI DBI Type
+A/B mode, MIPI DPI/DBI Type C mode, MIPI DSI video mode, MIPI DSI command
+mode and MDDI mode. The interface mode is selected by the external hardware
+pins BS[3:0].
+
+Currently, only the MIPI DSI video mode is supported.
+
+Required properties:
+  - compatible: should be a panel's compatible string
+  - reg: the virtual channel number of a DSI peripheral as described in [1]
+  - reset-gpios: a GPIO spec for the reset pin
+
+Optional properties:
+  - vdd1-supply: I/O and interface power supply
+  - vdd2-supply: analog power supply
+  - vdd3-supply: logic power supply
+  - dsi-vcc-supply: DSI and MDDI power supply
+  - vpp-supply: OTP programming voltage
+  - bs0-gpios: a GPIO spec for the pin BS0
+  - bs1-gpios: a GPIO spec for the pin BS1
+  - bs2-gpios: a GPIO spec for the pin BS2
+  - bs3-gpios: a GPIO spec for the pin BS3

+Example:
+	panel {
+		compatible = "truly,tft480800-16-e-dsi";
+		reg = <0>;
+		pinctrl-names = "default";
+		pinctrl-0 = <&pinctrl_mipi_panel>;
+		reset-gpios = <&gpio6 11 GPIO_ACTIVE_LOW>;
+		bs2-gpios = <&gpio6 14 GPIO_ACTIVE_HIGH>;
+	};
