Subject: [PATCH v3 2/3] Input: edt-ft5x06 - Set wake/reset values on resume/suspend
Date: Wed, 18 Jul 2018 20:27:18 +0200	[thread overview]
Message-ID: <20180718182719.29663-3-mylene.josserand@bootlin.com> (raw)
In-Reply-To: <20180718182719.29663-1-mylene.josserand@bootlin.com>

On resume and suspend, set the value of wake and reset gpios
to be sure that we are in a know state after suspending/resuming.
