Subject: [PATCH 05/21] media: atomisp: ov2680: Add init_cfg pad-op
Date: Mon, 29 May 2023 12:37:25 +0200 [thread overview]
Message-ID: <20230529103741.11904-6-hdegoede@redhat.com> (raw)
In-Reply-To: <20230529103741.11904-1-hdegoede@redhat.com>
Having an init_cfg to initialize the passed in subdev-state is
important to make which == V4L2_SUBDEV_FORMAT_TRY ops work when
userspace is talking to a /dev/v4l2-subdev# node.
Copy the ov2680_init_cfg() from the standard drivers/media/i2c/ov2680.c
driver.
This is esp. relevant once support for cropping is added where
the v4l2_subdev_state.pads[pad].try_crop rectangle needs to be set
correctly for set_fmt which == V4L2_SUBDEV_FORMAT_TRY calls to work.
