Subject: [PATCH v1 0/9] Add AMD ISP4 driver
Hello,
AMD ISP4 is the AMD image processing gen 4 which can be found in HP ZBook Ultra G1a 14 inch Mobile Workstation PC ( Ryzen AI Max 385)
(https://ubuntu.com/certified/202411-36043)
This patch series introduces the initial driver support for the AMD ISP4 including
- Powers up/off and initializes ISP HW
- Configures and kicks off ISP FW
- Interacts with APP using standard V4l2 interface by video node
- Controls ISP HW and interacts with ISP FW to do image processing
- Support enum/set output image format and resolution
- Support queueing buffer from app and dequeueing ISP filled buffer to App
- Starts/stops sensor and mipi csi when camera App starts/stops streaming.
- It supports libcamera ver0.2 SimplePipeline
- It is verified on qv4l2, cheese and qcam
- It is verified together with following patches
platform/x86: Add AMD ISP platform config for OV05C10 (https://lore.kernel.org/all/20250514215623.522746-1-pratap.nirujogi@amd.com/)
media: i2c: Add OV05C10 camera sensor driver (https://lore.kernel.org/all/20250408221246.911508-1-pratap.nirujogi@amd.com/)
pinctrl: amd: isp411: Add amdisp GPIO pinctrl (https://github.com/torvalds/linux/commit/e97435ab09f3ad7b6a588dd7c4e45a96699bbb4a)
i2c: amd-isp: Add ISP i2c-designware driver (https://github.com/torvalds/linux/commit/d6263c468a761cd4c89887073614394ac48441e1)
drm/amd/amdgpu: Add GPIO resources required for amdisp (https://gitlab.freedesktop.org/agd5f/linux/-/commit/ad0f5966ed8297aa47b3184192b00b7379ae0758)
AMD ISP4 Key features:
- Processes bayer raw data from the connected sensor and output them to different YUV formats
- Downscale input image to different output image resolution
- Pipeline to do image processing on the input image including demosaic, denoise, 3A, etc
It passes v4l2 compliance test, the test reports for:
(a) ov05c10 device /dev/v4l-subdev0
(b) amd_isp_capture device /dev/video0
