This series splits the existing meson-g12b-odroid-n2.dts into a common
dtsi and dts, and then adds new bindings and dts for the ODROID-N2+
which uses an Amlogic S922X rev.C chip that Hardkernel supports with
the same OPPs as the A311D.
Changes since v1 at [1]:
- rebase on khilman's v5.10/dt64
- get all review tags from v1
- use the A311D OPPs, after review of Vendor kernel, the Rev, C uses the same OPPs (freq + voltage)
as the A311D SoC of the same family

From: Christian Hewitt <[email protected]>
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.
