Subject: [PATCH v2 08/12] USB: EHCI: register dependency parser for firmware nodes
Date: Wed, 1 Jul 2015 11:41:03 +0200 [thread overview]
Message-ID: <1435743667-11987-9-git-send-email-tomeu.vizoso@collabora.com> (raw)
In-Reply-To: <1435743667-11987-1-git-send-email-tomeu.vizoso@collabora.com>
So others can find out whether a firmware node depends on a phy as
specified in bindings/usb/nvidia,tegra20-ehci.txt.
