From: Hans de Goede Date: Mon, 29 May 2023 10:37:25 +0000 (+0100) Subject: media: atomisp: ov2680: Add init_cfg pad-op X-Git-Tag: v6.6.7~2421^2~59 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b1b2d3992623290833f7f4ddea1986c7f123f3ad;p=platform%2Fkernel%2Flinux-starfive.git media: atomisp: ov2680: Add init_cfg pad-op 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.
