Subject: [PATCH] media: i2c: imx471: Set max analog gain to 960
Date: Wed, 2 Sep 2026 15:06:53 +0800 [thread overview]
Message-ID: <20260902070653.29186-1-hpa@redhat.com> (raw)
The maximum analog gain was previously restricted to resolve image
flickering and overexposure issues. With recent developments in
libcamera, this limit can now be restored to its original value of
960 to ensure image brightness is properly evaluated and adjusted.
