Subject: [PATCH v2 03/12] usb: ehci-hcd: notify phy when connect change
Date: Mon, 21 May 2012 17:23:48 +0800 [thread overview]
Message-ID: <1337592237-5090-4-git-send-email-richard.zhao@freescale.com> (raw)
In-Reply-To: <1337592237-5090-1-git-send-email-richard.zhao@freescale.com>
It still has below limitations:
- it does not work for multi-phy ehci
- the best place is after debounce, but I can't get
phy there
