Subject: ARM: dts: STiH410: Handle interconnect clock required by EHCI/OHCI (USB)

From: Lee Jones <[email protected]>

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)
