From 8e0d368a59bf87efa5ee4daea142527d01447864 Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Tue, 11 Sep 2018 17:47:04 +0900 Subject: [PATCH] dt-bindings: usb: renesas_usbhs: add clock-names property R-Car Gen3 needs to enable clocks of both host and peripheral. Otherwise, other side device cannot work correctly. So, this patch adds a property of clock-names for R-Car Gen3 as an optional.
