Subject: [PATCH v5 06/25] media: i2c: imx258: Make V4L2_CID_VBLANK configurable.
Date: Wed, 1 May 2024 09:24:23 -0600 [thread overview]
Message-ID: <20240501152442.1072627-7-git@luigi311.com> (raw)
In-Reply-To: <20240501152442.1072627-1-git@luigi311.com>
From: Dave Stevenson <dave.stevenson@raspberrypi.com>
The values and ranges of V4L2_CID_VBLANK are all computed,
so there is no reason for it to be a read only control.
Remove the register values from the mode lists, add the
handler, and remove the read only flag.
