From: Yegor Yefremov <yegorslists@xxxxxxxxxxxxxx> This patch series aims to reintroduce the mctrl_gpio helpers for 8250 UARTs. There are some UARTs that use GPIO signals as a wakeup-sourse. The first patch addresses this issue and tries to destinguish GPIO usage via searching for "wakeup-sourse" property. Though it must be decided whether this property is secure to use for this purpose.
