Subject: [PATCH v6 07/23] media: i2c: imx258: Split out common registers from the mode based ones
Date: Sun,  2 Jun 2024 14:13:29 -0600
Message-ID: <20240602201345.328737-8-git@luigi311.com>

From: Dave Stevenson <dave.stevenson@raspberrypi.com>

Out of all the registers that are defined for each mode, only around
10 differ between the modes.

Split the table into common and mode specific ones.
