Subject: [PATCH 04/16] media: i2c: ov9282: Remove pixel rate from mode definition
Date: Wed,  5 Oct 2022 16:27:57 +0100	[thread overview]
Message-ID: <20221005152809.3785786-5-dave.stevenson@raspberrypi.com> (raw)
In-Reply-To: <20221005152809.3785786-1-dave.stevenson@raspberrypi.com>

The pixel rate is determined by the PLL setup in the common
registers, not by the mode specific registers, therefore
remove it from the mode definition and define it for all modes.
