Subject: [PATCH v3 0/5] Add Arm Mali-C55 Image Signal Processor Driver
Date: Tue, 5 Mar 2024 16:48:27 +0000 [thread overview]
Message-ID: <20240305164832.2055437-1-dan.scally@ideasonboard.com> (raw)
Hello all
This patchset introduces a driver for Arm's Mali-C55 Image Signal Processor.
The driver uses the media controller API and in this initial support implements
both of the ISP's capture pipelines allowing a range of output formats plus
downscaling and cropping. The capture pipelines are named "Full resolution" and
"Downscale" and so abbreviated FR and DS throughout the driver.
The driver exposes 4 V4L2 subdevices:
- mali-c55 isp: input data formatting
- mali-c55 tpg: test pattern generator (modeled as a camera sensor entity)
- mali-c55 resizer fr: downscale / crop and format setting for the FR pipe
- mali-c55 resizer ds: downscale / crop and format setting for the DS pipe
Conspicuously missing from the list are subdevices for the ISP's statistics and
parameters; work is progressing in these areas and we plan on introducing them
in later series on top of this one.
Thanks
Dan
