From 6eb89f9ee2b64ffb021e1b58ada7e8768ef37165 Mon Sep 17 00:00:00 2001 From: Lina Iyer Date: Tue, 12 Mar 2019 17:23:13 -0600 Subject: [PATCH] dt-bindings: of: irq: document properties for wakeup interrupt parent Some interrupt controllers in a SoC, are always powered on and have a select interrupts routed to them, so that they can wakeup the SoC from suspend. Add wakeup-parent DT property to refer to these interrupt controllers.
