Subject: [PATCH 5/5] Input: ti_am335x_tsc: Mark IRQ as wakeup capable
Date: Sat, 30 Jun 2018 16:03:18 +0530 [thread overview]
Message-ID: <20180630103318.25355-6-vigneshr@ti.com> (raw)
In-Reply-To: <20180630103318.25355-1-vigneshr@ti.com>
On AM335x, ti_am335x_tsc can wake up the system from suspend, mark the
IRQ as wakeup capable, so that device irq is not disabled during system
suspend.
