Subject: [PATCH 10/13] usb: mtu3: support ip-sleep wakeup for MT8183
Date: Mon, 22 Mar 2021 11:13:49 +0800 [thread overview]
Message-ID: <1616382832-28450-10-git-send-email-chunfeng.yun@mediatek.com> (raw)
In-Reply-To: <1616382832-28450-1-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 follow IPM rule.
Due to the index 2 already used by many DTS, it's better to keep
it unchanged for backward compatible, treat specific ones without
following IPM rule as revision 1.x, meanwhile reserve 3~10 for later
revision that follows the IPM rule.
