Subject: [PATCH v2 1/3] media: i2c: adv748x: Simplify regmap configuration
Date:   Tue, 27 Feb 2018 15:05:48 +0000

From: Kieran Bingham <kieran.bingham@ideasonboard.com>

The ADV748x has identical map configurations for each register map. The
duplication of each map can be simplified using a helper macro such that
each map is represented on a single line.

Define ADV748X_REGMAP_CONF for this purpose use it to create the tables.
