The following commit, in 4.9 kernel:
commit 2d7007153f0c ("[media] media: videobuf2: Restructure vb2_buffer")
added some changes to the v4l2 structures that were not properly
included in the existing driver after the rebase from 4.1. Hence, when a
new buffer was filled by the v4l2 core, the flags field in
vb2_v4l2_buffer structure contained a pointer and, depending on the
pointer value, the v4l2 core considered that the buffer was already
dequeued, signaling the error to userspace. The issue appeared
intermittently, after multiple reboots.This patch fixes it.

mx6s-csi 21c4000.csi: dma_alloc_coherent of size 0 failedSigned-off-by: Robby Cai

For power saving, the camera is set ON/OFF by 'PWDN' pin.
However, the DQBUF timeout problems have been observed occasionally when
do the resolution switch for the camera. The reason could be that the power
for the camera is set to off then on when do the switch, but the delay time
is not enough for camera to go stable. The patch sets it to an empirical
value and it has passed over 3-day stress test.Signed-off-by: Robby Cai

Without the filter function, the dma_request_channel() API could possibly get
a sdma channel. The dma_request_channel() API does not return error but the
consequent operations on that channel will be invalid then the upper level
application expects to be stuck.The patch added the filter functions to get right dma channel for the fix.

The patch is to fix the issue,
mipi csi unit test mx6s_v4l2_capture.out can not work in 2nd time.In ov5647 driver, clock and data lane will been setting to LP11 mode
when stream off. And the mode will been changed to LP00 mode
at the begin of ov5647 initialization.
If MIPI CSI DPHY in power on state, it will begin to work after
clock and data lane level changed, even ov5647 is not ready.
MIPI PHY may lose ov5647 signal.Fixed the issue with:
i. Stream off ov5647 when ov5647 driver probe.
ii. Add 5ms delay after software reset bit set.
iii.Setting both clock and data lane in LP00 when stream off.Signed-off-by: Sandor Yu
