Subject: [PATCH 1287/1795] media: rcar-vin: move max width and height
information to chip information
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
On Gen3 the max supported width and height will be different from Gen2.
Move the limits to the struct rvin_info to prepare for Gen3 support.
