Subject: ARM: dts: STiH410: Handle interconnect clock required by EHCI/OHCI (USB)
From: Lee Jones <lee.jones@xxxxxxxxxx>
commit 7e9d2850a8db4e0d85a20bb692198bf2cc4be3b7 upstream.
The STiH4{07,10} platform contains some interconnect clocks which are used
by various IPs. If this clock isn't handled correctly by ST's EHCI/OHCI
drivers, their hub won't be found, the following error be shown and the
result will be non-working USB:
[ 97.221963] hub 2-1:1.0: hub_ext_port_status failed (err = -110)
