From ac315f66be96c5a423382efb559f193e5b786226 Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Wed, 21 Oct 2020 18:33:02 +0100 Subject: [PATCH] dtoverlays: Correct CSI2 settings for ov9281 OV9281 appears to drop the clock to LP mode between frames, but the overlay didn't define this at both ends of the CSI2 link. The overlay also had an incorrect link frequency defined, not that the driver ever checked for one. Fix both issues.
