Subject: [PATCH v2 1/3] input: touchscreen: edt-ft5x06: don't make device a wakeup source by default
Date: Thu, 17 May 2018 11:05:50 +0200	[thread overview]
Message-ID: <20180517090552.5704-2-daniel@zonque.org> (raw)
In-Reply-To: <20180517090552.5704-1-daniel@zonque.org>

Allow configuring the device as wakeup source through device properties, as
not all platforms want to wake up on touch screen activity.

The I2C core automatically reads the "wakeup-source" DT property to
configure a device's wakeup capability, and board supports files can set
I2C_CLIENT_WAKE in the flags.
