From 7359fac5a47897e6587ac82896257a60c700ac7d Mon Sep 17 00:00:00 2001 From: Benoit Parrot Date: Mon, 30 Sep 2019 10:06:37 -0300 Subject: [PATCH] media: i2c: ov2659: Fix for image wrap-around in lower resolution Based on recently found sensor configuration examples, it was discovered that when scaling and binning are used for the lower resolutions (i.e. 640x480, 320x240) the read offset has to be increased otherwise the image appears to be wrapped around.
