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
overclock to 2.4GHz on the big cluster and 2.0GHz on the little cluster.
The series has a soft-dependency on proposed changes to N2 audio [0]
from Jerome Brunet so will need a v2 rebase once they are applied
(basic tests for this series on N2 and N2+ are with them applied).

2.17.1
HardKernel ODROID-N2+ uses an Amlogic S922X rev. C chip capable of higher
clock speeds than the original ODROID-N2. Hardkernel supports the big cpu
cluster at 2.4GHz and the little cpu cluster at 2.0GHz. Opp points and
regulator changess are from the HardKernel Linux kernel sources.

Okay, I will send corrected v2 and with model name changed.

N2+ is currently the only known device with RevC chip (and shipping with
a huge heatsink) so we don’t know. I prefer to to put them in the board
dts for now and move to a common dtsi in the future once we’ve seen more
devices in the wild and proven they can handle the overclock.

According to the ODROID wiki those values are already in the
overclocking range:
https://wiki.odroid.com/odroid-n2/hardware/overclocking
From what I can tell, for ODROID-N2 upstream Linux so far used defaults
from meson-g12b-s922x.dtsi, which were 1896MHz for the A53 and 1704MHz
for the A73 (so it seems currently the A73 running even 100MHz below
"Stock").
I guess we should pick either Stock or Overclock for the two models.
Unless there is another good reason not to?
