* Add ODROID-N2+ support Add ODROID-N2+ support with the new SoC revision c. Extend the U-Boot script: Assume ODROID-N2 if the SoC revision is "a" (there are only "a" revision SoCs on ODROID N2) and assume N2+ otherwise. Currently using overclock mode as proposed in the upstream kernel patches. * Update hassos-hook.sh Co-authored-by: Pascal Vizeli <pascal.vizeli@syshack.ch>

Subject: [PATCH 10/10] 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. 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.
