Kyrocera 3.5 LCD Display Driver for iMx6ul

Hi,

I currently have imx6ul development board, I need to use kyrocera 3.5 LCD display.

I made a frequency change in the imx6ul-evk.dtsi file
/* Parallel LCD FRC pinctrl_lcdif_dat18_23*/
&lcdif {
 pinctrl-names = "default";
 pinctrl-0 = <&pinctrl_lcdif_dat0_17
       &pinctrl_lcdif_clken
    &pinctrl_lcdif_dat0_17  
    &pinctrl_lcdif_clken
    &pinctrl_lcdif_hvsync
    &pinctrl_lcdif_reset>;
 display = <&f07a0102>;
 status = "okey";

 f07a0102: display@0
  bits-per-pixel = <16>;
  bus-width = <18>;
  /* FRC  */
  //lcd_reset_gpio = <&gpio3 14 0>;
  lcd_panel = "FRCKYROCERA";

  display-timings {
   native-mode = <&timing0>;
   timing0: timing0 {
    clock-frequency = <6500000>;
    hactive = <320>;
    hfront-porch = <10>;
    hsync-len = <20>;
    hback-porch = <58>;
    hsync-active = <0>;

    vactive = <240>;
    vfront-porch = <2>;
    vsync-len = <4>;
    vback-porch = <16>;
    vsync-active = <0>;

    de-active = <1>;
    pixelclk-active = <1>;
   };
  };
 };
};

But the frequency is not changed to 6.5 Mhz.
Can you help me and point the file which loads Display Timing0 parameters?


Do you have any driver code that can be used for Kyrocera LCD? 

 

Thank you ,
David Zhou
