展讯平台手机camera驱动移植_9863 s5k3l8驱动

平台：展讯 系统:Android 7 、8、9应该是一样的 ，10的变化较大，下一篇文章再写。

camera 移植

\vendor\sprd\modules\libcamera\sensor\sensor_drv\classic 目录下放入对应的sensor驱动代码（驱动代码一般是厂商提供）。

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\kxxxx (此处kxxxx为平台名或项目名)

BoardConfig.mk

CAMERA_SENSOR_TYPE_BACK := "gc5025 gc8024 s5k3l8"
CAMERA_SENSOR_TYPE_FRONT := "sub_gc2385"

kernel4.14/arch/arm/boot/dts
kxxxx.dtsi 电压配置
此处需要查看对应sensor的datasheet明确各路供电是LDO还是PMIC，以及电压是多少。

        vddcama: ldo@5 {
            reg = <5>;
            regulator-name = "vddcama";
            sprd,default-microvolt = <1800000>;
            sprd,step-microvolt = <10000>;
            regulator-min-microvolt = <1200000>;
            regulator-max-microvolt = <3750000>;
            regulator-microvolt-offset = <0>;
            sprd,hide-offset = <1000>;
        };

.mk
添加文件或改动文件的同级或上级mk文件要进行检查，以免出现编译不到的情况。
好了，就简单写到这里，如有疏漏敬请见谅。
