MTK驱动------camera、af驱动跟flashlight驱动添加

这里是以mt6739+kernel4.4平台添加gc5025，fm50af为例

1.device/mediatek/common/kernel-headers/kd_imgsensor.h添加摄像头ID与名称

#define GC5025_SENSOR_ID				0x5025
#define SENSOR_DRVNAME_GC5025_MIPI_RAW			"gc5025_mipi_raw"

2.在项目配置文件device/mediateksample/k39tv1_bsp_1g/ProjectConfig.mk修改camera信息

CUSTOM_HAL_FLASHLIGHT = constant_flashlight
CUSTOM_HAL_IMGSENSOR = gc5025_mipi_raw
CUSTOM_HAL_LENS = fm50af dummy_lens

CUSTOM_HAL_MAIN_BACKUP_LENS = 
CUSTOM_HAL_MAIN_IMGSENSOR = gc5025_mipi_raw
CUSTOM_HAL_MAIN_LENS = fm50af 
副摄像头为空：
CUSTOM_HAL_SUB_BACKUP_LENS = 
CUSTOM_HAL_SUB_IMGSENSOR = 
CUSTOM_HAL_SUB_LENS = 

CUSTOM_KERNEL_IMGSENSOR = gc5025_mipi_raw

CUSTOM_KERNEL_LENS = fm50af dummy_lens

CUSTOM_KERNEL_MAIN_BACKUP_LENS = 
CUSTOM_KERNEL_MAIN_IMGSENSOR = gc5025_mipi_raw
CUSTOM_KERNEL_MAIN_LENS = fm50af
副摄像头为空：
CUSTOM_KERNEL_SUB_BACKUP_LENS = 
CUSTOM_KERNEL_SUB_IMGSENSOR = 
CUSTOM_KERNEL_SUB_LENS = 

3.kernel-4.4/arch/arm/configs/k39tv1_bsp_1g_debug_defconfig配置文件

CONFIG_CUSTOM_KERNEL_IMGSENSOR="gc5025_mipi_raw"

#CONFIG_MTK_FLASHLIGHT_RT4505=y
CONFIG_MTK_FLASHLIGHT_DUMMY_GPIO=y

4.kernel-4.4/arch/arm/configs/k39tv1_bsp_1g_defconfig配置文件

CONFIG_CUSTOM_KERNEL_IMGSENSOR="gc5025_mipi_raw"

#CONFIG_MTK_FLASHLIGHT_RT4505=y
CONFIG_MTK_FLASHLIGHT_DUMMY_GPIO=y

5.kernel-4.4/drivers/misc/mediatek/imgsensor/inc/kd_imgsensor.h

#define GC5025_SENSOR_ID				0x5025
#define SENSOR_DRVNAME_GC5025_MIPI_RAW			"gc5025_mipi_raw"

6.kernel-4.4/drivers/misc/mediatek/imgsensor/src/common/v1/目录添加gc5025_mipi_raw驱动文件

7.kernel-4.4/drivers/misc/mediatek/imgsensor/src/common/v1/imgsensor_sensor_list.c添加camera gc5025

+#if defined(GC5025_MIPI_RAW)
+    {GC5025_SENSOR_ID, SENSOR_DRVNAME_GC5025_MIPI_RAW, GC5025MIPI_RAW_SensorInit},

8.kernel-4.4/drivers/misc/mediatek/imgsensor/src/common/v1/imgsensor_sensor_list.h

UINT32 GC5025MIPI_RAW_SensorInit(PSENSOR_FUNCTION_STRUCT *pfFunc);

9.kernel-4.4/drivers/misc/mediatek/imgsensor/src/mt6739/camera_hw/imgsensor_cfg_table.c添加上下电信息

+#if defined(GC5025_MIPI_RAW)
+	{
+		SENSOR_DRVNAME_GC5025_MIPI_RAW,
+		{
+			{SensorMCLK, Vol_High, 0},
+			{PDN, Vol_Low, 1},
+			{RST, Vol_Low, 10},
+			{DOVDD, Vol_1800, 5},
+			{DVDD, Vol_1200, 5},
+			{AVDD, Vol_2800, 5},
+			{AFVDD, Vol_2800, 5},
+			{PDN, Vol_High, 5},
+			{RST, Vol_High, 5}
+		},
+	},
+#endif

10.在kernel-4.4/drivers/misc/mediatek/flashlight/flashlight-device.c增加闪光灯配置信息

-		{0, 0, 0, "flashlights-rt4505", 0, 0},
+		{0, 0, 0, "flashlights-dummy-gpio", 0, 0},

 

11.在dts上增加闪光灯配置k39tv1_bsp_1g.dts跟mt6739.dts

+	/**flashlights_rt4505: flashlights_rt4505 {
 		compatible = "mediatek,flashlights_rt4505";
+	};*/
+	strobe: strobe {
+		compatible = "mediatek,flashlights_dummy_gpio";
 	};

+&strobe {
+	pinctrl-names = "xxx_high",
+			"xxx_low";
+	pinctrl-0 = <&xxx_high>;
+	pinctrl-1 = <&xxx_low>;
+	status = "okay";
+};
&pio {
+	xxx_high: xxx_high {
+		pins_cmd_dat {
+			pins = ;
+			slew-rate = <1>;
+			output-high;
+		};
+	};
	xxx_low: xxx_low {
+		pins_cmd_dat {
+			pins = ;
+			slew-rate = <1>;
+			output-low;
+		};
+	};
+
+};

12.vendor/mediatek/proprietary/custom/mt6739/hal/imgsensor/目录添加厂家提供的文件gc5025_mipi_raw

13.vendor/mediatek/proprietary/custom/mt6739/hal/imgsensor_src/sensorlist.cpp添加信息

+#if defined(GC5025_MIPI_RAW)
+    RAW_INFO(GC5025_SENSOR_ID, SENSOR_DRVNAME_GC5025_MIPI_RAW, NULL),

14.vendor/mediatek/proprietary/custom/mt6739/hal/lens/src/lenslist.cpp

 #if defined(FM50AF)
+	{GC5025_SENSOR_ID, FM50AF_LENS_ID, "FM50AF", pFM50AF_getDefaultData},
 #endif

15.vendor/mediatek/proprietary/custom/mt6739/hal/sendepfeature/添加gc5025_mipi_raw文件夹放置效果文件

           config.ftbl.gc5025mipi_raw.h

16.vendor/mediatek/proprietary/hardware/mtkcam/legacy/platform/mt6739/core/featureio/drv/strobe/flashlight_drv.cpp更改

让获取duty没有返回值，这样才能正常使用闪光灯
-        err = getPreOnTimeMsDuty(m_duty, &minPreOnTime);
+        /**err = */getPreOnTimeMsDuty(m_duty, &minPreOnTime);

 

17.添加af驱动位置

  kernel-4.4\drivers\misc\mediatek\lens\main\common

   vendor\mediatek\proprietary\custom\mt6739\hal\lens

18.闪光灯使用的驱动文件

 kernel-4.4/drivers/misc/mediatek/flashlight/flashlights-dummy-gpio.c

 

另外，还要修改dws文件的i2c地址以及一些ldo电源的输出配置，dts上的camera是配置好的，不需要修改
