Subject: [PATCH 15/28] media: ti-vpe: cal: remove wait when stopping camerarx
Date: Mon, 12 Apr 2021 14:34:44 +0300	[thread overview]
Message-ID: <20210412113457.328012-16-tomi.valkeinen@ideasonboard.com> (raw)
In-Reply-To: <20210412113457.328012-1-tomi.valkeinen@ideasonboard.com>

Asserting ComplexIO reset seems to affect the HW (ie. asserting reset
will break an active capture), but the RESET_DONE bit never changes to
"reset is ongoing" state. Thus we always get a timeout.

Drop the wait, as it seems to achieve nothing.
