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: i2c: vgxy61: Fix device name

2024-06-15T09:16:40+00:00

Rename 'st-vgxy61' to 'vgxy61', dropping the vendor prefix to follow the same naming scheme as the vast majority of device drivers. The device tree binding does not fall into binding rename exceptions and therefore must not be changed. Keep its legacy name.

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.
