Here's a new version of the firmware driver.  This series applies on
top of for-rpi-next from Lee Jones's tree:

git://git.kernel.org/pub/scm/linux/kernel/git/rpi/linux-rpi.git

But it won't actually probe without merging in mailbox-for-next:

I've dropped the pm-domains code for now, since it wasn't doing
anything useful for us yet without the drivers/base support.  However,
this code has been useful for building a proper clk provider for the
Pi, which can be found at:

Andrea Merello apparently got a cpufreq driver working on top of the
non-DT version of this clk provider:

I think we might manage with a generic dt-cpufreq implementation,
though.
