展讯 lcd移植

参考平台：sp9832e android 9.0

一、uboot移植

1.添加驱动文件

路径：

u-boot15/drivers/video/sprdfb/lcd/lcd_rm67162_454x454_mipi_boe.c

2.添加编译规则

路径：

u-boot15/drivers/video/sprdfb/lcd/Makefile

修改：

obj-$(CONFIG_LCD_RM67162_454X454_MIPI_BOE) += lcd_rm67162_454x454_mipi_boe.o

3.引用lcd接口

路径：

u-boot15/drivers/video/sprdfb/sprdfb_panel.c

修改：

extern struct panel_spec lcd_st7797_400x400_mipi_spec;

static struct panel_cfg panel_cfg[] = {
.
.
.
#ifdef CONFIG_LCD_ST7797_400X400_MIPI
{
    .lcd_id = 0x7797,
    .panel = &lcd_st7797_400x400_mipi_spec,
},
#endif

4.配置编译选项

路径：

u-boot15/include/configs/${project}.h

修改：

#define CONFIG_LCD_ST7797_400X400_MIPI

二、kernel配置

1.添加dtsi文件

路径：

kernel4.4/arch/arm/boot/dts/lcd/lcd_st7797_400x400_mipi.dtsi

2.引用dtsi文件

路径：

kernel4.4/arch/arm/boot/dts/${project}.dts

修改：

#include lcd/lcd_st7797_400x400_mipi.dtsi

panel-drivers = < 
	&lcd_st7797_mipi
