      1、修改驱动源码

      内核源码驱动路径：tina-d1-open/lichee/linux-5.4/drivers/video/fbdev/sunxi/disp2/disp/lcd
      uboot源码驱动路径：tina-d1-open/lichee/brandy-2.0/u-boot-2018/drivers/video/sunxi/disp2/disp/lcd
      因为驱动框架是一样的，我们只需要修改屏幕初始化参数就可以了。这里我修改的就是tft08006.c文件

+       {0xF5, 26, {0xFF, 0xFE, 0xFC, 0xFA, 0xF8, 0xF4, 0xF0, 0xE8, 0xE0, 0xD0, 0xC0, 0xA0, 0x80, 0x7F, 0x5F, 0x3F, 0x2F, 0x1F, 0x17, 0x0F,0x0B, 0x07, 0x05, 0x03, 0x01, 0x00} },

+ +       {REGFLAG_DELAY, REGFLAG_DELAY, {20}},
+       {REGFLAG_END_OF_TABLE, REGFLAG_END_OF_TABLE, {}}

      2、修改设备树

      这里只把重要的参数列出来了，内核设备树和uboot设备树要保持一致。

      ;----------------------------------------------
&lcd0 {
    lcd_used            = <1>;

    lcd_driver_name     = "tft08006";
    lcd_backlight       = <100>;
    lcd_if              = <4>;

    lcd_x               = <800>;
    lcd_y               = <1280>;
    lcd_width           = <80>;
    lcd_height          = <80>;
    lcd_dclk_freq       = <60>;                

    lcd_pwm_used        = <1>;
    lcd_pwm_ch          = <2>;
    lcd_pwm_freq        = <1000>;
    lcd_pwm_pol         = <0>;
    lcd_pwm_max_limit   = <255>;
    lcd_hbp             = <40>;
    
	lcd_ht              = <860>;
	lcd_hspw            = <20>;
	lcd_vbp             = <24>;
	lcd_vt              = <1330>;
	lcd_vspw            = <4>;


	lcd_dsi_if          = <0>;     
	lcd_dsi_lane        = <4>;

      3、触摸屏驱动配置

      到Tina根目录下make kernel_menuconfig将下面驱动配置上
      在这里插入图片描述
      修改设备树
      在twi0下增加触摸屏子节点
      在这里插入图片描述

      4、编译打包、测试

      在这里插入图片描述
