[PATCH v3 0/2] media: v4l2-subdev: Make .init_cfg() an internal operation

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

 



Hello,

This patch series addresses a historical issue in the V4L2 subdev
in-kernel API.

The subdev .init_cfg() pad operation used to initialize a
v4l2_subdev_pad_config structure. This was changed to initializing a
v4l2_subdev_state a while ago, but the operation wasn't renamed, and
stayed a pad operation. Not only is the name confusing for new
developers, it is also the only pad operation that doesn't operate on a
pad, leading to more confusion.

This series addresses those two issues by renaming the operation to
.init_cfg() and moving it to the subdev internal operations, in patch
2/2. Most of the preparatory patches from v1 have been applied by Sakari
already, leaving only 1/2 for a respin due to issues with the
first version.

The series is based on Sakari's latest test branch ([1]), containing
patches scheduled for v6.8. I would like to get it merged in v6.8 as
well, as it touches many drivers and rebasing it is painful. Mauro,
Hans, for this reason, I would appreciate if you could review this
series now and not when Sakari or I will send a pull request.

The VSP1 driver has been tested on a Renesas R-Car M3-N Salvator-XS. The
rest of the series is compile-tested only.
