input: migor_ts: add wakeup support
Add wakeup support to the migor_ts driver. If user space has enabled wakeup, use set_irq_wake() during suspend and resume. With this patch the migor_ts driver can be used to wake the system from suspend. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
