Subject: [PATCH v2 2/3] ARM: dts: add rk3288 ehci usb devices
Date: Wed, 30 Jul 2014 13:00:11 -0700	[thread overview]
Message-ID: <1406750412-15592-3-git-send-email-dianders@chromium.org> (raw)
In-Reply-To: <1406750412-15592-1-git-send-email-dianders@chromium.org>

From: Kever Yang <kever.yang@rock-chips.com>

rk3288 has two kind of usb controller; this adds the ehci variant for
host0 and hsic.

At the moment we don't add any phys for these controllers, but the
default settings seem to work OK.

There is a hardware problem in ohci controller which make it
unavailable and host0 controller can only support high-speed devices.
