From fbd4676cc2930ba40d507eaadf3ff06d3eba7e6a Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Mon, 13 Feb 2017 07:24:36 -0200 Subject: [PATCH] [media] tc358743: put lanes in STOP state before starting streaming Without calling tc358743_set_csi after stopping streaming (or calling tc358743_s_dv_timings or tc358743_set_fmt from userspace after stopping the stream), the i.MX6 MIPI CSI2 input fails waiting for lanes to enter STOP state when streaming is started again.
