Subject: [PATCH 3/3] arm64: dts: renesas: beacon: Fix HSUSB ref clock references
Date: Wed, 30 Jun 2021 12:30:42 -0500 [thread overview]
Message-ID: <20210630173042.186394-3-aford173@gmail.com> (raw)
In-Reply-To: <20210630173042.186394-1-aford173@gmail.com>
The RZ/G2 boards expect there to be an external clock reference for
USBHS controller. For the Beacon boards, this reference clock
is controlled by a programmable versaclock. Because the RZ/G2
family has a special clock driver when using an external clock,
the third clock reference in the USBHS node needs to point to this
special clock, called usb2_clksel, and the 4th clock is the versaclock.
