泰山派_移植ov8858摄像头

内核中已经适配了ov8858的驱动源码，只需要

开启对应的驱动编译选项
配置设备树

/home/shelton/Workspaces/source/sdk/rockchip/rk3566_tspi/tspi_linux_sdk_repo_20240131/kernel/drivers/media/i2c/ov8858.c

开启OV5695驱动编译选项

kernel kconfig

shell

#选中预选的配置
source buildroot/build/envsetup.sh
# 所有配置项的目录
#/home/shelton/Workspaces/source/sdk/rockchip/rk3566_tspi/tspi_linux_sdk_repo_20240131/buildroot/configs

# 进入图形化配置
make menuconfig
# 65 rockchip_rk3566_defconfig

#保存配置
make savedefconfig

此时kernel的 kconfig 会加载默认的配置项tspi_linux_sdk_repo_20240131/kernel/arch/arm64/configs/rockchip_linux_defconfig

kconfig由多个配置文件组合而成，因此可以直接在rockchip_linux_defconfig中添加配置

在 rockchip_linux_defconfig 中添加 CONFIG_VIDEO_OV8858=y

shell

# CONFIG_MEDIA_SUBDRV_AUTOSELECT is not set
CONFIG_VIDEO_OV5695=y
#...
CONFIG_VIDEO_OV8858=y

此时tspi_linux_sdk_repo_20240131/kernel/arch 中的 Makefile的这个目标就生效了

shell

obj-$(CONFIG_VIDEO_OV8858)	+= ov8858.o

tspi_linux_sdk_repo_20240131/kernel/drivers/media/i2c 中出现 ov8858.o 即为添加成功

修改设备树

设备树的路径为

shell

/home/shelton/Workspaces/source/sdk/rockchip/rk3566_tspi/tspi_linux_sdk_repo_20240131/kernel/arch/arm64/boot/dts/rockchip

创建ov8858对应的设备树

基于ov5695的设备树 tspi-rk3566-csi-v10.dtsi 修改数据链路

这是一个真实、对称、可验证的硬件连接

Sensor → CSI-2 DPHY → ISP 的数据通路

[ov8858] ──⇄── [csi2_dphy0] ──⇄── [rkisp_vir0]
              (in/out endpoints)

remote-endpoint 的指向如上图

shell

//摄像头D-PHY接口
&csi2_dphy0 {
	status = "okay";
	ports {
		port@0 {
			reg = <0>;
			dphy0_in: endpoint@1 {
				reg = <1>;
				remote-endpoint = <&ov8858_out>;
				data-lanes = <1 2 3 4>;
			};
		};

		port@1 {
			reg = <1>;
			dphy0_out: endpoint@1 {
				reg = <1>;
				remote-endpoint = <&isp0_in>;
			};
		};
	};
};

//图像处理接口
&rkisp_vir0 {
	status = "okay";
	port {
		isp0_in: endpoint@0 {
			reg = <0>;
			remote-endpoint = <&dphy0_out>;
		};
	};
};

&i2c4 {
		port {
			ov8858_out: endpoint {
				remote-endpoint = <&dphy0_in>; 
				data-lanes = <1 2 3 4>;  // 2lane为 <1 2>, 4lane为 <1 2 3 4>
			};
		};
	};
};
