一。修改LCD panel参数，文件： Da8xx-fb.c

static struct da8xx_panel known_lcd_panels[] = {    /* Sharp LCD035Q3DG01 */    [0] = {        .name = "Sharp_LCD035Q3DG01",        .width = 320,        .height = 240,        .hfp = 8,        .hbp = 6,        .hsw = 0,        .vfp = 2,        .vbp = 2,        .vsw = 0,        .pxl_clk = 4608000,        .invert_pxl_clk = 1,    },    /* Sharp LK043T1DG01 */    [1] = {        .name = "Sharp_LK043T1DG01",        .width = 480,        .height = 272,        .hfp = 2,        .hbp = 2,        .hsw = 41,        .vfp = 3,        .vbp = 3,        .vsw = 10,        .pxl_clk = 7833600,        .invert_pxl_clk = 0,    },    /* LinCuiting SET 2015_10_14  LCD70P800480 */     [2] = {          .name = "MCUzone_LCD70",          .width = 800,          .height = 480,          .hfp = 209,          .hbp = 25,//46,          .hsw = 19,          .vfp = 21,          .vbp = 12,//23,          .vsw = 9,          .pxl_clk = 33300000,          .invert_pxl_clk = 0,     },};

二。da8xx_lcdc_platform_data加入自己的屏，文件：Devices-da8xx.c

struct da8xx_lcdc_platform_data mcuzone_lcd70p800480_pdata = {    .manu_name      = "MCUzone",    .controller_data    = &lcd_cfg,    .type           = "MCUzone_LCD70",};

三。修改头文件。文件：Da8xx.h， Mux.h
1.Da8xx.h

extern const short da8xx_lcdc_platform_data mcuzone_lcd70p800480_pdata;

2.Mux.h

    /* GPIO function */    DA850_GPIO2_0,    DA850_GPIO2_4,    DA850_GPIO2_6,    DA850_GPIO2_8,    DA850_GPIO2_14,    DA850_GPIO2_15,    DA850_GPIO4_0,    DA850_GPIO4_1,    DA850_GPIO1_4,    DA850_GPIO1_5,    DA850_GPIO0_11,    DA850_GPIO6_13,    DA850_RTC_ALARM,    DA850_GPIO7_4,    DA850_GPIO0_15,    DA850_GPIO6_9,    DA850_GPIO6_10, //lct set    DA850_GPIO8_10, //lct set

四。Da850.c

    /* GPIO function */    。。。。。。。。。。。    。。。。。。。。。。。    MUX_CFG(DA850, GPIO8_10,    18, 28, 15, 8,  false) //lct set

五。板级信息：注册屏。文件：Board-da850-evm.c

#define DA850_LCD_PWR_PIN       GPIO_TO_PIN(8, 11)//lct set#define DA850_LCD_BL_PIN        GPIO_TO_PIN(8, 10)//lct set
