Subject: [PATCH 03/11] arm64: dts: meson: add support for the ODROID-N2+
|
|
|
|
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.
