Subject: [PATCH 2/2] platform/x86: surfacepro3: Support for wakeup from suspend-to-idle
Date: Wed, 10 Jan 2018 13:26:35 +0100 [thread overview]
Message-ID: <6492549.QWquAG8VGe@aspire.rjw.lan> (raw)
In-Reply-To: <4046497.JI7UjL75gC@aspire.rjw.lan>
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Modify surface_button_notify() to make it wake up the system from
suspend-to-idle (by reporting "hard" wakeup events while suspended)
and add wakeup initialization to surface_button_add() for wakeup
events reported by this driver to work at all.
