Subject: [PATCH AUTOSEL 6.12 339/486] media: i2c: imx219: Correct the minimum vblanking value
Date: Mon, 5 May 2025 18:36:55 -0400 [thread overview]
Message-ID: <20250505223922.2682012-339-sashal@kernel.org> (raw)
In-Reply-To: <20250505223922.2682012-1-sashal@kernel.org>
From: David Plowman <david.plowman@raspberrypi.com>
[ Upstream commit e3b82d49bf676f3c873e642038765eac32ab6d39 ]
The datasheet for this sensor documents the minimum vblanking as being
32 lines. It does fix some problems with occasional black lines at the
bottom of images (tested on Raspberry Pi).
