From d365bc92475205312c0064e92398ead059156bd9 Mon Sep 17 00:00:00 2001 From: Chiranjeevi Rapolu Date: Wed, 24 Jan 2018 23:34:39 -0500 Subject: media: ov13858: Avoid possible null first frame Previously, the sensor, with default settings, was outputting SOF without data. This results in frame sync error on the receiver side. Now, configure the sensor to output SOF with MIPI data for all frames. This avoids possible null first frame on the bus.
