From 800a4ea17eb86b1f2cfad9fd7a252a3803bc5264 Mon Sep 17 00:00:00 2001 From: Marcel Ziswiler Date: Mon, 9 Jan 2023 14:19:59 +0100 Subject: [PATCH] ARM: dts: colibri-imx6ull: improve wake-up with gpio key The pin GPIO5_IO01 externally pulls down, it is required to sequentially connect this pin (signal WAKE_MICO#) to +3v3 and then disconnect it to trigger a wakeup interrupt. Adding the flag GPIO_PULL_DOWN allows the system to be woken up just connecting the pin GPIO5_IO01 to +3v3.
