From 89954fe81b818b49419019095173a0d7e8f765a8 Mon Sep 17 00:00:00 2001 From: Mark Hasemeyer Date: Tue, 2 Jan 2024 14:07:33 -0700 Subject: arm64: dts: mediatek: mt8173: Enable cros-ec-spi as wake source The cros_ec driver currently assumes that cros-ec-spi compatible device nodes are a wakeup-source even though the wakeup-source property is not defined. Some Chromebooks use a separate wake pin, while others overload the interrupt for wake and IO. With the current assumption, spurious wakes can occur on systems that use a separate wake pin. It is planned to update the driver to no longer assume that the EC interrupt pin should be enabled for wake. Add the wakeup-source property to all cros-ec-spi compatible device nodes to signify to the driver that they should still be a valid wakeup source.
