Subject[PATCH] mfd: cros_ec_spi: set wakeup capability
Date
From: Prathyush K <prathyush.k@samsung.com>

Set the device as wakeup capable and register the wakeup source.

Note: Though it makes more sense to have the SPI framework do this,
(either via device tree or by board_info)
this change is as per an existing mail chain:

Note that I don't have suspend/resume actually working upstream, but I
see that /sys/bus/spi/drivers/cros-ec-spi/spi2.0/power/wakeup exists
with this patch and doesn't exist without it.
