1、deconfig文件增加MIPI配置

在arch/arm/configs/rk3288_defconfig添加配置：?

CONFIG_LCD_MIPI=y

CONFIG_MIPI_DSI=y

CONFIG_RK32_MIPI_DSI=y

2、dts文件夾增加dtsi tinming1改成timing0

3、dts取消LCD_BOX.dtsi 增加MIPI dtsi

I2C4關于RGB的信號，把他disabled

VGA也是disabled

進入make muenuconfig把VGA關閉

uboot更改：

/home/jd/3288/u-boot/drivers/video/screen、lcd-mipi.c? ?復制保存

1、

static int rk_mipi_screen_init_dt(struct mipi_screen *screen)

{

struct mipi_dcs_cmd_ctr_list? *dcs_cmd;

u32 i,cmds[400]; 本來是20現(xiàn)改成400

2、

static int rk_mipi_screen_init_dt(struct mipi_screen *screen)

{

struct device_node *childnode, *grandchildnode, *root;

struct mipi_dcs_cmd_ctr_list? *dcs_cmd;

struct list_head *pos;

struct property *prop;

enum of_gpio_flags flags;

u32 value, i, debug, gpio, ret, cmds[44], length;

? ? ? ? ?本來是25現(xiàn)改成400

?

/home/jd/3288/u-boot/drivers/video/transmitter/mipi_dsi.h

struct dcs_cmd {

u8 type;

u8 dtype;

? ? u8 dsi_id;

? ? u8 cmd_len;

int cmds[400];本來是32現(xiàn)改成400

int delay;

? ? char name[32];

?

在uboot目錄下執(zhí)行：

make rk3288_config

make

在uboot目錄下生成RK3288UbootLoader_V2.30.10.bin

?

kenel更改：

1、

kernel\drivers\video\rockchip\transmitter\mipi_dsi.h

#define INVALID_GPIO? ? ? ? -1

?

struct dcs_cmd {

u8 type;

u8 dtype;

? ? u8 dsi_id;

? ? u8 cmd_len;

int cmds[400];本來是32現(xiàn)改成400

int delay;

? ? char name[64];

2、

kernel\drivers\video\rockchip\screen\lcd_mipi.c? 復制保存

#ifdef CONFIG_LCD_MIPI

static int rk_mipi_screen_init_dt(struct mipi_screen *screen)

{

struct device_node *childnode, *grandchildnode, *root;

struct mipi_dcs_cmd_ctr_list *dcs_cmd;

struct list_head *pos;

struct property *prop;

enum of_gpio_flags flags;

u32 value, i, debug, gpio, ret, cmds[400], length;本來是64現(xiàn)改成400

?

static int rk_mipi_screen_init_dt(struct mipi_screen *screen)

{

struct mipi_dcs_cmd_ctr_list *dcs_cmd;

u32 i, cmds[400];? ;本來是64現(xiàn)改成400

int length;

int err;

int node;

const void *blob;

struct fdt_gpio_state gpio_val;

int noffset;

?注：kernel改完之后編譯提示數(shù)據(jù)太長，在makemenuconfig里面把Kernel hacking改成2048

dtsi中把復位設成高

make menuconfig中把boot logo打開

打開debg信息

driver/video/rockchip/transmitter/rk32_mipi_dsi.c 中的:

#defineMIPI_DBG(x...) printk(KERN_INFO x)。

driver/video/rockchip/screen/lcd_mipi.c 中的:

#defineMIPI_SCREEN_DBG(x...) printk(KERN_ERR x)。
