Hi,

I want to interface imx6ul processor with SPI LCD which is based on ili9806e as per below link:

5.0 inch 480*854, ILI9806E, SPI+RGB interface, high brightness, full viewing angle IPS LCD with capacitive touch panel, …

I made following changes in my dtsi file of my processor.
&ecspi1 {
   fsl,spi-num-chipselects = <1>;
   cs-gpios = <&gpio4 26 0>;
   pinctrl-names = "default";
   pinctrl-0 = <&pinctrl_ecspi1_1>;
   status = "okay";

   ili9806e@0{
       compatible = "ilitek,ili9806";
       reg = <0>;
       status = "okay";
       spi-max-frequency = <10000000>;
       spi-cpol;
       spi-cpha;
       rotate = <0>;
       bgr;
       fps = <50>;
       buswidth = <9>;
       reset-gpios = <&gpio4 22 0>;
        debug = <0>;
   };
};

        pinctrl_ecspi1_1: ecspi1grp {
           fsl,pins = <
               MX6UL_PAD_CSI_DATA07__ECSPI1_MISO       0x100b1
               MX6UL_PAD_CSI_DATA06__ECSPI1_MOSI       0x100b1
               MX6UL_PAD_CSI_DATA04__ECSPI1_SCLK       0x100b1
               MX6UL_PAD_CSI_DATA05__GPIO4_IO26        0x100b1
           >;
       };

Please help to interface LCD using linux frame buffer.

Thanks,
