Subject: [PATCH 2/3] usb: host: xhci-plat: enable BROKEN_PED quirk if platform requested
Date: Thu, 17 Nov 2016 17:01:20 +0200 [thread overview]
Message-ID: <1479394881-13863-3-git-send-email-rogerq@ti.com> (raw)
In-Reply-To: <1479394881-13863-1-git-send-email-rogerq@ti.com>
From: Felipe Balbi <balbi@ti.com>
In case 'quirk-broken-port-ped' property is passed in via device property,
we should enable the corresponding BROKEN_PED quirk flag for XHCI core.
[rogerq@ti.com] Updated code from platform data to device property
and added DT binding.
