Subject: [PATCH v2 06/13] usb: xhci-mtk: support ip-sleep wakeup for MT8183
Date: Tue, 23 Mar 2021 15:02:48 +0800 [thread overview]
Message-ID: <1616482975-17841-6-git-send-email-chunfeng.yun@mediatek.com> (raw)
In-Reply-To: <1616482975-17841-1-git-send-email-chunfeng.yun@mediatek.com>
Add support ip-sleep wakeup for MT8183, it's similar to MT8173,
and it's also a specific one, but not following IPM rule.
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 3~10 for
later revision that follows the IPM rule.

v2:
1. fix typo suggested by Sergei
2. fix build warning - Woverflow
3. modify revision format
