From aed7425d65108bc6e7cb2f64a11aa35b9f5e4397 Mon Sep 17 00:00:00 2001 From: Oleksij Rempel Date: Mon, 23 Oct 2023 11:33:37 +0200 Subject: net: dsa: microchip: use wakeup-source DT property to enable PME output KSZ switches with WoL support signals wake event over PME pin. If this pin is attached to some external PMIC or System Controller can't be described as GPIO, the only way to describe it in the devicetree is to use wakeup-source property. So, add support for this property and enable PME switch output if this property is present.
