Subject: [PATCH 2/4] input: ti_am335x_tsc: Increase sequencer delay time
Date: Tue, 13 Aug 2013 17:48:17 +0100	[thread overview]
Message-ID: <1376412499-21007-3-git-send-email-zubair.lutfullah@gmail.com> (raw)
In-Reply-To: <1376412499-21007-1-git-send-email-zubair.lutfullah@gmail.com>

Before checking PEN UP event, IRQ delays for this amount
of time to let FSM stabilize. Previously, with only the
TSC driver in IRQ mode, this delay was sufficient.

The delay is increased slightly to accomodate if the ADC
is also being used simultaneously in continuous mode.
