[PATCH 12/13] media: i2c: ov5647: Use the same PLL config for full, 1080p, and binned modes
Posted by Jai Luthra 3 months, 2 weeks ago
From: Dave Stevenson <dave.stevenson@raspberrypi.com>

In order to simplify the driver slightly, use the same PLL
configuration, and hence pixel rate and link frequency (to be
added) for the full, 1080p, and binned modes.

I get a value of 87499965, so I guess this is correct approximation
