media: uapi: mali-c55-config: Remove version identifier

2026-01-06T09:14:13+00:00

The Mali C55 driver uses the v4l2-isp framework, which defines its own versioning number which does not need to be defined again in each platform-specific header. Remove the definition of mali_c55_param_buffer_version enumeration from the Mali C55 uAPI header. Signed-off-by: Jacopo Mondi Reviewed-by: Daniel Scally Signed-off-by: Hans Verkuil

media: uapi: c3-isp: Fix documentation warning

2025-12-03T09:07:37+00:00

Building htmldocs generates a warning: WARNING: include/uapi/linux/media/amlogic/c3-isp-config.h:199 error: Cannot parse struct or union! Which correctly highlights that the c3_isp_params_block_header symbol is wrongly documented as a struct while it's a plain #define instead. Fix this by removing the 'struct' identifier from the documentation of the c3_isp_params_block_header symbol.

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: Convert Amlogic C3 to V4L2 extensible params

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

With the introduction of common types for extensible parameters format, convert the c3-isp-config.h header to use the new types. Factor-out the documentation that is now part of the common header and only keep the driver-specific on in place. The conversion to use common types doesn't impact userspace as the new types are either identical to the ones already existing in the C3 ISP uAPI or are 1-to-1 type convertible.

media: uapi: Introduce V4L2 generic ISP types

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

Introduce v4l2-isp.h in the Linux kernel uAPI. The header includes types for generic ISP configuration parameters and will be extended in the future with support for generic ISP statistics formats. Generic ISP parameters support is provided by introducing two new types that represent an extensible and versioned buffer of ISP configuration parameters. The v4l2_params_buffer represents the container for the ISP configuration data block. The generic type is defined with a 0-sized data member that the ISP driver implementations shall properly size according to their capabilities. The v4l2_params_block_header structure represents the header to be prepend to each ISP configuration block.
