[PATCH 0/5] Add Arm Mali-C55 Image Signal Processor Driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

Thanks
Dan
