Hi
I'm tring to add support for MIPI DSI interface (that will be converted into LVDS on my board) on i.MX7 SOM.
i'm using dts with:
&mipi_dsi {
disp-dev = "mipi_dsi";
compatible = "fsl,imx7d-mipi-dsi"; // also "imx7d-mipi-dsi" added to mipi_dsi.c with values of imx6
lcd_panel = "TRULY-WVGA";
dev_id = <0>;// doesn't know why, driver requirement
disp_id = <0>;// doesn't know why, from example
gpr = <&gpr>;
disp-power-on-supply = <®_mipi_dsi_pwr_on>;
resets = <&mipi_dsi_reset>;
status = "okay";
};
reg_mipi_dsi_pwr_on: mipi_dsi_pwr_on {
compatible = "regulator-fixed";
regulator-name = "mipi_dsi_pwr_on";
gpio = <&gpio4 16 GPIO_ACTIVE_HIGH>;
enable-active-high;
};
mipi_dsi_reset: mipi-dsi-reset {
compatible = "gpio-reset";
reset-gpios = <&gpio4 17 GPIO_ACTIVE_LOW>;
reset-delay-us = <50>;
#reset-cells = <0>;
};
