Subject: [PATCH v7 1/2] media: i2c: imx412: Assert reset GPIO during probe
Date: Fri, 23 Jan 2026 17:19:55 +0800 [thread overview]
Message-ID: <20260123-imx412-v7-1-e58303f2b76b@oss.qualcomm.com> (raw)
In-Reply-To: <20260123-imx412-v7-0-e58303f2b76b@oss.qualcomm.com>
Assert the reset GPIO before first power up. This avoids a mismatch where
the first power up (when the reset GPIO defaults deasserted) differs from
subsequent cycles.
