I handle on an ArmSoM-W3 (RK3588) project,but tried couple times still unable to access the imx415 camera.In my limited experience with imx415 camera I have looked around and apparently I have got the solution here below.Wanted to know if it’s good practice to do that and what would be the best way to do that?
1、Environment
- [Mastering RK3588 from Beginner to Expert] Series Contents
- SoC: rk3588
- Sensor: imx415
- Board: ArmSoM-W3
- Linux: 5.10
2、Introduction：imx415
- Brand：SONY
- Sensor：IMX415
- Interface：MIPI CSI
3、Driver porting
Rockchip provides a camera_module_support_list for their solutions.
For this ArmSoM-W3 (RK3588) project, the IMX415 (sensor) was selected from Rockchip's support list.
3.1 Driver Source Files and Corresponding Scripts
There is no need to port the driver,because the default SDK from Rockchip has pre-integrated drivers for all supported camera models, compiled into the kernel.
Confirm the following information on the driver porting:
- Source Code
3588_linux/3588_linux5.10_v1.0.5/kernel/drivers/media/i2c/imx415.c 3588_linux/3588_linux5.10_v1.0.5/kernel/drivers/media/i2c/Makefile 3588_linux/3588_linux5.10_v1.0.5/kernel/drivers/media/i2c/Kconfig 3588_linux/3588_linux5.10_v1.0.5/kernel/arch/arm64/configs/rockchip_linxu_defconfig
- Makefile Script
obj-$(CONFIG_VIDEO_IMX415) += imx415.o
- Kconfig Script
config VIDEO_IMX415
tristate "Sony IMX415 sensor support"
depends on I2C && VIDEO_V4L2 && VIDEO_V4L2_SUBDEV_API
depends on MEDIA_CAMERA_SUPPORT
help
This is a Video4Linux2 sensor driver for the Sony
IMX415 camera.
To compile this driver as a module, choose M here: the
module will be called imx415.

3.2 dts Device Tree
1）Camera Connection Diagram
The key pins connecting IMX415 to the SoC include: i2c, rst, pwdn, mclk, MIPI Clk, MIPI Data
2） Schematics
From the schematics, the key pin mappings are:
reset signal：gpio4 A0 power0 down signal：gpio1 B0 I2C channel：3 clock：CLK_MIPI_CAMARAOUT_M3

The device tree information is ultimately converted into an i2c_client, and passed to the IMX415 driver imx415_probe(){ compatible = "imx415"; needs to align with of_match_table in the driver for consistency.

From entity 63 information we can see:
The full entity name is: m00_b_imx415 3-001a
It is a V4L2 subdev (Sub-Device) Sensor Its node is /dev/v4l-subdev2, applications (e.g. v4l2-ctl) can open it for configuration
It has only one output (Source) node, labeled pad0
Its output format is [fmt:SGBRG10_1X10/3864x2192@10000/300000 field:none
crop.bounds:(12,16)/3840x2160], where SBGGR10 is an mbus-code abbreviation
Its Source pad0 links to pad0 of "rockchip-csi2-dphy0", and current status is ENABLED.

5、Testing
Once debugging worked, running gst-launch-1.0 enables to view the input from the imx415 camera directly:
gst-launch-1.0 v4l2src device=/dev/video11 ! video/x-raw,format=NV12,width=3840,height=2160, framerate=30/1 ! xvimagesink
