From 21939f003ad09355d9c975735750bb22aa37d8de Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Mon, 23 Jan 2017 14:19:59 +0200 Subject: [PATCH] usb: host: xhci-plat: enable BROKEN_PED quirk if platform requested 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.
