Subject: [PATCH v2 3/3] arm64: dts: meson: add support for the ODROID-N2+
Date: Tue, 15 Sep 2020 17:24:32 +0200	[thread overview]
Message-ID: <20200915152432.30616-4-narmstrong@baylibre.com> (raw)
In-Reply-To: <20200915152432.30616-1-narmstrong@baylibre.com>

From: Christian Hewitt <christianshewitt@gmail.com>

HardKernel ODROID-N2+ uses an Amlogic S922X rev. C chip capable of higher
clock speeds than the original ODROID-N2.

The rev. C support a slighly higher VDDCPU_A & VDDCPU_B voltages and supports
the same OPPs as the Amlogic A311D SoC from the same G12B family.
