From fc51da4c15fa1e00cd1f855e14e8b05abbc555c7 Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Wed, 4 Mar 2020 15:42:14 +0900 Subject: [PATCH] dt-bindings: clock: renesas: rcar-usb2-clock-sel: Fix clock[-name]s properties Since the hardware requires to enable both USB 2.0 host and peripheral functional clock, this patch fixes the documentation. Fortunately, no one has this device node for now, so that we don't need to think of backward compatibility.
