展讯平台驱动移植

平台 9850KH，Android 7.0

一、LCD移植

文件修改：u-boot15\include\configs\sp9850kh_1h10.h

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

kernel\arch\arm64\boot\dts\sprd\sp9850kh-common.dtsi

在configs\sp9850kh_1h10.h  添加宏定义

#define CONFIG_FB_LCD_VDD18_VCAMA
#define CONFIG_FB_LCD_JD9366_MIPI_LONGYU_S5703
#define CONFIG_SYS_WHITE_ON_BLACK
#ifdef  LCD_TEST_PATTERN
#define CONSOLE_COLOR_RED 0xf800
#define CONSOLE_COLOR_GREEN 0x07e0
#define CONSOLE_COLOR_YELLOW 0x07e0
#define CONSOLE_COLOR_BLUE 0x001f
#define CONSOLE_COLOR_MAGENTA 0x001f
#define CONSOLE_COLOR_CYAN 0x001f

u-boot15\drivers\video\sprdfb\lcd 目录下放入lcd_jd9366_00_mipi_longyu_s5703.c

修改makefile: 

obj-$(CONFIG_FB_LCD_JD9366_MIPI_LONGYU_S5703)  += lcd_jd9366_00_mipi_longyu_s5703.o

 修改 sprdfb_panel.c

添加：extern struct panel_spec lcd_jd9366_00_mipi_longyu_s5703_spec; lcd_jd9366_00_mipi_longyu_s5703.c有定义

panel_cfg panel_cfg[]数组中添加

#ifdef CONFIG_FB_LCD_JD9366_MIPI_LONGYU_S5703
{
    .lcd_id = 0x936600,    //ID型号加电频
    .panel = &lcd_jd9366_00_mipi_longyu_s5703_spec,
},
#endif

在\kernel\arch\arm64\boot\dts\sprd\lcd 目录下添加lcd_jd9366_00_mipi_longyu_s5703.dtsi

sp9850kh-common.dtsi 中添加：

#include "lcd/lcd_jd9366_00_mipi_longyu_s5703.dtsi"
#include "sc2721.dtsi"
#include "sprd-battery.dtsi"
#include "sp9850kh-modem.dtsi"
#include
#include "sprd-sound-sharkl.dtsi"

panel_if: sprd-panel-if {
        compatible = "sprd-panel-if";
        #address-cells = <1>;
        #size-cells = <0>;
        panel-drivers = <
            &lcd_jd9366_00_mipi_longyu_s5703
            &l505_lcd_ili9881c_weiyi_mipi_hd
            &l505_lcd_jd9365_zgd_mipi
            &l505_lcd_otm1289a_kd_mipi
            &l505_lcd_jd9365_hf_mipi
            &lcd_ili9881p_mipi_hd
            &lcd_ili9881c_mipi_hd
            &lcd_nt35597_mipi_2k_fpga
            &lcd_dummy_rgb
        >;

二、TP移植

去平台的 deconfig 文件中打开 CONFIG_TOUCHSCREEN_GSLX680 宏 

驱动代码放入kernel\drivers\input\touchscreen 目录下

修改makefile kconfig

驱动：gslx680

makefile:

obj-$(CONFIG_TOUCHSCREEN_GSLX680)    += gslx680/

kconfig:

      
config TOUCHSCREEN_GSLX680
    tristate "GSLX680 Touchscreen interface support"
    depends on I2C
    help
      Say Y here if enable support for the GSLX680 multi fingers
      touchscreen controller.

      If unsure, say N.

      To compile this driver as a module, choose M here: the
      module will be called gslx680.

kernel\arch\arm64\boot\dts\sprd\sp9850kh-smt-1h10.dts 添加：

&i2c3 {
    status = "okay";

    gslX680@40{
        compatible = "gslX680,gslX680_ts";
        reg = <0x40>;
        gpios = <&ap_gpio 145 0
            &ap_gpio 144 0>;
        vdd_name = "vdd28";
        virtualkeys = <580 108 1317 40 40
                   172 396 1317 40 40
                   158 612 1317 40 40>;
        TP_MAX_X = <720>;
        TP_MAX_Y = <1440>;
    };
};

idh\device\sprd\sharklj1\common\rootdir\system\usr\idc 添加：gslX680_ts.idc

三、camera 移植

\vendor\sprd\modules\libcamera\sensor\sensor_drv\classic 目录下放入对应的sensor代码

修改vendor\sprd\modules\libcamera\sensor sensor_cfg.c

#ifdef GC5005
extern SENSOR_INFO_T g_gc5005_mipi_raw_info;
#endif
#ifdef GC5024
extern SENSOR_INFO_T g_gc5024_mipi_raw_info;
#endif

const SENSOR_MATCH_T back_sensor_infor_tab[] = {
// gc area
#ifdef GC5025
    {MODULE_SUNNY, "gc5025", &g_gc5025_mipi_raw_info, {&dw9714_drv_entry, 0}, NULL},
#endif

#ifdef S5K3L8
    {MODULE_SUNNY, "s5k3l8", &g_s5k3l8xxm3_mipi_raw_info, {&dw9714_drv_entry, 0}, NULL},
#endif

#ifdef GC5005
    {MODULE_SUNNY, "gc5005", &g_gc5005_mipi_raw_info, {&dw9714_drv_entry, 0}, NULL},
#endif
#ifdef GC8024
    {MODULE_SUNNY, "gc8024", &g_gc8024_mipi_raw_info, {&dw9714_drv_entry, 0}, NULL},
#endif
#ifdef GC030A
    {MODULE_SUNNY, "gc030a", &g_gc030a_mipi_raw_info, {NULL, 0}, NULL},
#endif
...........
 

    {0, "0", NULL, {NULL, 0}, NULL}};

const SENSOR_MATCH_T front_sensor_infor_tab[] = {
// gc area
#ifdef SUB_GC2385
    {MODULE_SUNNY, "sub_gc2385", &g_gc2385_mipi_raw_info, {NULL, 0}, NULL},
#endif
#ifdef GC5005
    {MODULE_SUNNY, "gc5005", &g_gc5005_mipi_raw_info, {NULL, 0}, NULL},
#endif
  .................

    {0, "0", NULL, {NULL, 0}, NULL}};

修改 device\sprd\sharklj1\sp9850kh_1h10
