From ef159033e2ef9917c15335ba89bcbeb4270773c6 Mon Sep 17 00:00:00 2001
From: Andrey Gusakov <andrey.gusakov@cogentembedded.com>
Date: Tue, 11 Jun 2019 16:21:41 +0300
Subject: [PATCH 5/6] arm64: dts: renesas: ulcb-vb2: fix USB30 and HUB
- add two HUB nodes as HUB can populate one of two i2c addresses
depending on power supply start order. Driver just fixes few
registers values over i2c for proper operation.
- same driver handles reset gpio, so remove regulator.
- add pinctl for XHCI and remove PWEN regulator.
