I2C core already handles "wakeup-source" property (for OF). The static board files can instantiate clients with I2C_CLIENT_WAKE, so that's handled too, and I think ACPI has its own notion of annotating wakeup sources. > > dev_dbg(&client->dev, > "EDT FT5x06 initialized: IRQ %d, WAKE pin %d, Reset pin %d.\n", > -- > 2.14.3 > Thanks.

Allow configuring the device as wakeup source through device properties, as not all platforms want to wake up on touch screen activity. Note that by default, the device will now no longer be a wakeup source.
