media: uapi: Add controls for Mali-C55 ISP

2025-11-14T14:48:49+00:00

Add definitions and documentation for the custom control that will be needed by the Mali-C55 ISP driver. This will be a read only bitmask of the driver's capabilities, informing userspace of which blocks are fitted and which are absent.

media: uapi: Add controls for the THP7312 ISP

2023-12-04T09:37:46+00:00

The THP7312 is an external ISP from THine. As such, it implements a large number of parameters to control all aspects of the image processing. Many of those controls are already standard in V4L2, but some are fairly device-specific. Reserve a range of 32 controls for the device. The driver will implement 4 device-specific controls to start with, define and document them. 28 additional device-specific controls should be enough for future development.
