From 58020c9f14c8d884fd48434fbdbc659257cf46f3 Mon Sep 17 00:00:00 2001 From: Chiranjeevi Rapolu Date: Mon, 18 Sep 2017 19:47:43 -0300 Subject: [PATCH] [media] media: ov13858: Fix 4224x3136 video flickering at some vblanks Previously, with crop (0, 0), (4255, 3167), VTS < 0xC9E was resulting in blank frames sometimes. This appeared as video flickering. But we need VTS < 0xC9E to get ~30fps. Omni Vision recommends to use crop (0,8), (4255, 3159) for 4224x3136. With this crop, VTS 0xC8E is supported and yields ~30fps.
