The ODroid-C2 on-board USB Hub needs to to have it's reset signal set to

But this management must be part of the currently in-development Generic
Power Sequence patch that will allow a USB Controller driver to start and stop
a power sequence associated to the USB Bus.

In the meantime, a simple USB Hog will work to enable the USB Hub.

OdroidC2 GbE link breaks under heavy tx transfer. This happens even if the
MAC does not enable Energy Efficient Ethernet (No Low Power state Idle on

LPI state.

Disabling EEE advertisement on the phy prevent this feature to be
negociated with the link partner and solve the issue.

ARM64: dts: meson-gxbb-odroidc2: Disable SCPI DVFS

The current hardware is not able to run with all cores enabled at a
cluster frequency superior at 1536MHz.
But the currently shipped u-boot for the platform still reports an OPP
table with possible DVFS frequency up to 2GHz, and will not change since
the off-tree linux tree supports limiting the OPPs with a kernel parameter.
A recent u-boot change reports the boot-time DVFS around 100MHz and
the default performance cpufreq governor sets the maximum frequency.
Previous version of u-boot reported to be already at the max OPP and
left the OPP as is.
Nevertheless, other governors like ondemand could setup the max frequency
and make the system crash.

This patch disables the DVFS clock and disables cpufreq.
