From 52445887492ce9a4633f1548f85d6d75cef6437a Mon Sep 17 00:00:00 2001 From: Chunfeng Yun Date: Tue, 23 Mar 2021 15:02:44 +0800 Subject: [PATCH] dt-bindings: usb: mtk-xhci: add support wakeup for mt8183 and mt8192 These two HW of wakeup don't follow MediaTek internal IPM rule, both use a specific way, like as early revision of mt8173. Due to the index 2 already used by many DTS, it's better to keep it unchanged for backward compatibility, treat specific ones without following IPM rule as revision 1.x, meanwhile reserve 3~99 for later revisions with following the IPM rule.
