SPRD芯片安卓平台屏幕调试笔记
本文档以展锐平台SC9863A1为基础，屏幕以FT8057S为基础，点亮屏幕示例
·
本文档以展锐平台SC9863A1为基础，屏幕以FT8057S为基础。
一、原理图
以上图纸主要关注:reset引脚对应的GPIO
以上图纸关注：偏压IC型号、I2C接口、avdd&dvdd使用的GPIO口
以上图纸关注:IC型号、flash_en的GPIO、PWM控制是由GPIO还是由CABC
二、LCD信号要求
LCD信号要求参考《FT8057S_Data_Sheet_V0.1 .pdf》中的4.1节。
主要关注:avdd、avee、vddi的电压要求，芯片的mipi line数，以及其他特殊要求。
三、GPIO口配置
3.1使用工具配置初始化
使用以上工具设置GPIO，主要配置：gpio属性
根据以上原理图可知需要配置以下IO
AVDD:RFCTL16(GPIO7)
AVEE:U0CTS(GPIO62)
LCM_RESET:LCM_RSTN(GPIO50)
TP_RESET:EXTINT1(GPIO145) （TP的reset在incell屏幕中，会影响屏幕点亮，故也需要配置）I2C4:SIMCLK2(SCL4),SIMDAT2(SDA4) ：默认已经设置
FLASH_EN:GPIO32
{REG_PIN_U0CTS, BITS_PIN_AF(3)},
{REG_MISC_PIN_U0CTS, BITS_PIN_DS(1)|BIT_PIN_NULL|BIT_PIN_NUL|BIT_PIN_SLP_AP|BIT_PIN_SLP_WPD|BIT_PIN_SLP_OE},//LCM_AVEE
...
{REG_PIN_GPIO32, BITS_PIN_AF(3)},
{REG_MISC_PIN_GPIO32, BITS_PIN_DS(1)|BIT_PIN_NULL|BIT_PIN_NUL|BIT_PIN_SLP_AP|BIT_PIN_SLP_NUL|BIT_PIN_SLP_OE},//LCM_BL_EN
...
{REG_PIN_RFCTL16, BITS_PIN_AF(3)},
{REG_MISC_PIN_RFCTL16, BITS_PIN_DS(1)|BIT_PIN_NULL|BIT_PIN_NUL|BIT_PIN_SLP_AP|BIT_PIN_SLP_WPD|BIT_PIN_SLP_OE},//LCM_AVDD
3.2将IO口信息配置到代码中
该项目通过原理图识别为使用屏幕的CABC控制背光
修改以下文件:bsp\bootloader\lk\project\sp9863a_1h10.mk
CONFIG_LCM_GPIO_RSTN=50 \
CONFIG_LCM_GPIO_AVDDEN=7 \
CONFIG_LCM_GPIO_AVEEEN=62 \
CONFIG_LCM_GPIO_TP_RESET=145 \
LCD_I2C_BUS_NUM=4 \
LCD_I2C_SLAVER_ADDR=0X3E
修改以下文件:bsp\kernel5.15\kernel5.15\arch\arm64\boot\dts\sprd\sp9863a-1h10-overlay.dts
&dpu {
//sprd,backlight = <&pwm_backlight>;
};
&panel {
//sprd,backlight = <&pwm_backlight>;
avdd-gpio = <&ap_gpio 7 GPIO_ACTIVE_HIGH>;
avee-gpio = <&ap_gpio 62 GPIO_ACTIVE_HIGH>;
reset-gpio = <&ap_gpio 50 GPIO_ACTIVE_HIGH>;
};
四、初始化时序
屏幕上电时序参考《FT8057S_Data_Sheet_V0.1 .pdf》中的4.2.1.4节
根据以上信息我们可以修改init文件内的.power函数为
static int esky_ft8057s_vdo_hdp_boe_hy_power(int on)
{
int i, ret = 0;
u8 bias_config[7][2] = {{0x61, 0x2C}, {0x44, 0x96}, {0x61, 0x00},{0x00, 0x14},{0x01, 0x14},{0x03, 0x43},{0xff, 0x80}};
if (on) {
for (i = 0; i < sizeof(bias_config)/sizeof(bias_config[0]); i++) {
ret = i2c_send(LCD_I2C_BUS_NUM, LCD_I2C_SLAVER_ADDR, (unsigned char *)bias_config[i], ARRAY_SIZE(bias_config[i]));
if (ret < 0) {
pr_err("config lcd i2c bias power failed\n");
break;
}
}
sprd_gpio_request(CONFIG_LCM_GPIO_RSTN);
sprd_gpio_direction_output(CONFIG_LCM_GPIO_RSTN, 0);
#ifdef CONFIG_LCM_GPIO_TP_RESET
sprd_gpio_request(CONFIG_LCM_GPIO_TP_RESET);
sprd_gpio_direction_output(CONFIG_LCM_GPIO_TP_RESET, 1);
mdelay(5);
#endif
#ifdef CONFIG_LCM_GPIO_AVDDEN
sprd_gpio_request(CONFIG_LCM_GPIO_AVDDEN);
sprd_gpio_direction_output(CONFIG_LCM_GPIO_AVDDEN, 1);
mdelay(2);
#endif
#ifdef CONFIG_LCM_GPIO_AVEEEN
sprd_gpio_request(CONFIG_LCM_GPIO_AVEEEN);
sprd_gpio_direction_output(CONFIG_LCM_GPIO_AVEEEN, 1);
mdelay(2);
#endif
sprd_gpio_request(CONFIG_LCM_GPIO_RSTN);
sprd_gpio_direction_output(CONFIG_LCM_GPIO_RSTN, 1);
mdelay(5);
sprd_gpio_direction_output(CONFIG_LCM_GPIO_RSTN, 0);
mdelay(10);
sprd_gpio_direction_output(CONFIG_LCM_GPIO_RSTN, 1);
mdelay(20);
pr_err("ft8057s power no\n");
} else {
sprd_gpio_direction_output(CONFIG_LCM_GPIO_RSTN, 0);
mdelay(5);
}
return 0;
}
以上代码中，先使用I2C设置偏压IC的偏压电压，然后在将reset引脚设置为低电平，TPreset设置为高电平，设置avdd上电延时后设置avee上电，最后在设置reset高低高。
五、修改代码
5.1 设置mipi时序
在原厂给的代码中一般会给一个mipi的proch时序如下图，其中需要重点关注的信息有
VFP
VBP
HFP
HBP
HSYNC
VSYNC
line number(有的没有直接给出，需要向fae询问)
一般我们将上图给的推介时序填入《unisoc lcd(mipi) fps-phy_feq计算_c_v1.05.xlsm》文档中会生成一个适合芯片的时序如下：
从以上参数可以看出，计算的帧率不能满足60fps故我们需要将以上文档发给FAE或者直接与FAE沟通修改proch参数达到要求(点亮时可以先不要求proch参数)
将以上结果填入init文件
bsp\bootloader\lk\platform\sprd_shared\driver\video\sprd\lcd\lcd_ft8057s_ztd_mipi_hd.c
static struct panel_info lcd_ft8057s_mipi_hd_info = {
/* common parameters */
.lcd_name = "lcd_ft8057s_mipi_hd",
.type = SPRD_PANEL_TYPE_MIPI,
.bpp = 24,
// .fps = 60,
.width = 720,
.height = 1612,
/* DPI specific parameters */
.pixel_clk = 96000000, /*Hz*/
.rgb_timing = {
.hfp = 26,
.hbp = 14,
.hsync = 4,
.vfp = 445,
.vbp = 28,
.vsync = 6,
},
/* MIPI DSI specific parameters */
.phy_freq = 691000,
.lane_num = 4,
.work_mode = SPRD_MIPI_MODE_VIDEO,
.burst_mode = PANEL_VIDEO_BURST_MODE,
.bl_type = BL_TYPE_MIPI,
.bl_config_bit = 12,
.nc_clk_en = false,
};
5.2 设置init code
在通常的mipi屏幕，都需要下init code，以初始化屏幕的各种参数，通常fae会给类似以下文件的参数

以上文件需要转换为dsi_cmd_desc结构体形式（参考文档《103188__Kernel 5.15 LCD配置指导手册V1.4.pdf》）
并将修改后的参数写入（static uint8_t init_data[]）数组内，完整代码如下（由于init代码经过多次修改，故可能init代码可能有差异）

六、将文件合入代码编译
6.1lk阶段
在文件bsp\bootloader\lk\platform\sprd_shared\driver\video\sprd\lcd\panel_cfg.h 内添加panel_driver类型的外部变量（名称与之前修改的驱动文件内的一致）
extern struct panel_driver ft8057s_mipi_hd_driver;
并且在数组supported_panel[]内添加屏幕的指针
#ifdef CONFIG_LCD_FT8057S_MIPI_HD
{
.lcd_id = 0x8057,
.drv = &ft8057s_mipi_hd_driver,
},
#endif
在文件bsp\bootloader\lk\platform\sprd_shared\driver\video\sprd\rules.mk中添加驱动文件的编译规则，并使用宏控
ifeq ($(LCD_FT8057S_MIPI_HD),1)
GLOBAL_DEFINES += CONFIG_LCD_FT8057S_MIPI_HD
MODULE_SRCS += \
$(LOCAL_DIR)/esky_lcd/lcd_ft8057s_mipi_hd.c
endif
其中LCD_FT8057S_MIPI_HD为宏控名称，MODULE_SRCS为源码路径
在文件bsp\bootloader\lk\project\sp9863a_1h10.mk内添加
LCD_HX105FN01_IPS_HLX_MIPI_FHD := 1
使驱动文件编译进LK内
同时在bsp\kernel5.15\kernel5.15\arch\arm64\boot\dts\sprd\sp9863a-1h10-overlay.dts文件内添加
#include "lcd/lcd_ft8057s_mipi_hd.dtsi"
使驱动文件编译进dtb内
