Subject: [PATCH v8 05/28] rcar-vin: move chip information to own struct
Date: Wed, 29 Nov 2017 20:43:19 +0100 [thread overview]
Message-ID: <20171129194342.26239-6-niklas.soderlund+renesas@ragnatech.se> (raw)
In-Reply-To: <20171129194342.26239-1-niklas.soderlund+renesas@ragnatech.se>
When Gen3 support is added to the driver more than chip ID will be
different for the different SoCs. To avoid a lot of if statements in the
code create a struct chip_info to store this information.
And while we are at it sort the compatible string entries and make use
of of_device_get_match_data() which will always work as the driver is DT
only, so there's always a valid match.
