Merge tag 'sti-dt-for-v4.10-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/pchotard/sti into fixes
STi DT fix: Since v4.10-rc1, xhci is complaining in loop with : [ 801.953836] usb usb6-port1: Cannot enable. Maybe the USB cable is bad? [ 801.960455] xhci-hcd xhci-hcd.0.auto: Cannot set link state. [ 801.966611] usb usb6-port1: cannot disable (err = -32) set property "snps,dis_u3_susphy_quirk" in DT fix it. * tag 'sti-dt-for-v4.10-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/pchotard/sti: ARM: dts: STiH407-family: set snps,dis_u3_susphy_quirk Signed-off-by: Olof Johansson <olof@lixom.net>
