video: tegra: host: Improve timing of syncpt wait
nvhost_syncpt_wait_timeout() relies on sync point interrupt to signal reaching the sync point value. With low timeout values, the resolution is not good enough and an error is returned even when the value is reached. Update syncpoint value from hardware when doing a sync point wait and do an explicit check for reaching the value even if wait returns a timeout. bug 984166 bug 986788 bug 987597 Change-Id: I640e32cdcdfa66b8977eac273dd32f62bd72abd6 Signed-off-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-on: http://git-master/r/103827 Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Mayuresh Kulkarni <mkulkarni@nvidia.com> Reviewed-by: Juha Tukkinen <jtukkinen@nvidia.com>
