Subject: [PATCH 2/2] arm64: dts: renesas: Add usb2_clksel to RZ/G2 M/N/H
Date: Mon, 28 Dec 2020 14:22:21 -0600 [thread overview]
Message-ID: <20201228202221.2327468-2-aford173@gmail.com> (raw)
In-Reply-To: <20201228202221.2327468-1-aford173@gmail.com>
Per the reference manal for the RZ/G Series, 2nd Generation,
the RZ/G2M, RZ/G2N, and RZ/G2H have a bit that can be set to
choose between a crystal oscillator and an external oscillator.
Because only boards that need this should enable it, it's marked
as disabled by default for backwards compatibility with existing
boards.
