In BCM2711 the new ARGON ASB took over V3D. The old ASB is still present
with the ISP and H264 bits, and V3D is in the same place in the new ASB
as the old one.
As per the devicetree bindings, BCM2711 will provide both the old and
new ASB registers, so get both of them and pass them into
'bcm2835-
A new compatible string was introduced specifically for BCM2711, so make
use of it.

Add a new compatible string for bcm2711 and the option to provide a
third reg property for the board's new Argon ASB.
The new Argon ASB took over V3D, which is our only consumer of this
driver so far. The old ASB is still be present with ISP and H264 bits
but no V3D.

If there is a initramfs linked into the kernel which will be

Joel reported long preempt and irq off sequence in newidle_balance because
of a large number of cgroups in used and having to be updated. This
patchset moves the update outside newidle_imblance in order to enable
early abort during the updates in case of pending irq as an example.

idle load balance is the only user of update_nohz_stats and doesn't use
force parameter. Remove it

Yes, it does. I would like to
Remove the specific case for handling this_cpu outside for_each_cpu() loop
when running ILB. Instead we use for_each_cpu_wrap() and start with the
next cpu after this_cpu so we will continue to finish with this_cpu.
update_nohz_stats() is now used for this_cpu too and will prevents

Instead of waking up a random and already idle CPU, we can take advantage
of this_cpu being about to enter idle to run the ILB and update the
blocked load.
