This is based on the devices found in Odroid Go Advance/Super, so I've
left a lot of clocks out that don't seem to be used on those devices,
at least for this initial port.
Still quite incomplete, as it's missing a bunch of clocks. Do we
really need to implement support for all possible clocks from the SoC,
even if we have no drivers that use them?
There's also an issue with pmucru and cru ordering, which I added a
dirty workaround for. Under current circumstances cru will attach
before pmucru, and panic because it's missing the 'gpll' pll. I'm not
sure what's the proper way to make cru depend on pmucru, shouldn't
that be done automatically from the DT?
AFAICT MMC and USB works, and we can boot into multiuser using the
serial console.
I see some weird message from failing to set the frequency for cpll,
not sure what's going on with that.
Also there are some messages from cpufreq missing a regulator, I
haven't looked at what's missing for those.
This is the current boot log:
