Upstream must be stopped immediately after receiving the last EOF and before disabling the IDMA channel. This can be accomplished by moving upstream stream off to just after receiving the last EOF completion in prp_stop(). For symmetry also move upstream stream on to end of prp_start(). This fixes a complete system hard lockup on the SabreAuto when streaming from the ADV7180, by repeatedly sending a stream off immediately followed by stream on: while true; do v4l2-ctl -d1 --stream-mmap --stream-count=3; done Eventually this either causes the system lockup or EOF timeouts at all subsequent stream on, until a system reset. The lockup occurs when disabling the IDMA channel at stream off. Stopping the video data stream entering the IDMA channel before disabling the channel itself appears to be a reliable fix for the hard lockup.

Move upstream stream off to just after receiving the last EOF completion and disabling the CSI (and thus before disabling the IDMA channel) in csi_stop(). For symmetry also move upstream stream on to beginning of csi_start(). Doing this makes csi_s_stream() more symmetric with prp_s_stream() which will require the same change to fix a hard lockup.

Disable the CSI immediately after receiving the last EOF before stream off (and thus before disabling the IDMA channel). Do this by moving the wait for EOF completion into a new function csi_idmac_wait_last_eof(). This fixes a complete system hard lockup on the SabreAuto when streaming from the ADV7180, by repeatedly sending a stream off immediately followed by stream on: while true; do v4l2-ctl -d4 --stream-mmap --stream-count=3; done Eventually this either causes the system lockup or EOF timeouts at all subsequent stream on, until a system reset. The lockup occurs when disabling the IDMA channel at stream off. Disabling the CSI before disabling the IDMA channel appears to be a reliable fix for the hard lockup.

By historical reasons we defined firmware memory size to be 6MB even that the firmware size for all supported Venus versions is 5MBs. Correct that by compare the required firmware size returned from mdt loader and the one provided by DT reserved memory region. We proceed further if the required firmware size is smaller than provided by DT memory region. Reviewed-by:

This provides more power saving when the sensor is off. While at that, do the delay on power/clock enable even if the sensor driver itself doesn't control the GPIOs. This is required for the OLPC XO-1 platform, that lacks the proper power/reset properties in its DT, but needs the delay after the sensor is clocked up. Signed-off-by:
