  ARM: dts: bcm283x: Add 32-bit enable method for SMP (2017-08-14 20:09:44 +0200)

----------------------------------------------------------------
This pull request brings in a new SMP enable-method compat string,
which is needed to move the 32-bit SMP boot code out of the irqchip.

  ARM: bcm2836: Send event when onlining other cores (2017-08-15 10:52:26 -0700)

----------------------------------------------------------------
This pull request brings in two things.

One is to use sev() to wake up CPUs that might be sleeping when doing
the custom spin-table boot process in 32-bit mode (new firmware
versions will have the CPUs sleeping waiting for an event instead of
just spinning).  However, the irqchip maintainer objected to our SMP
code continuing to live in the driver, so we had to move it to
platsmp.c, and to do that we needed a new SMP enable-method to the DT
for the platsmp.c to attach to (thus the DT cross-merge in this PR).
The platsmp.c patch was acked by irqchip for going through arm-soc.

The other piece is a garbage-collection of the platform's stub clock
driver for early Raspberry Pi support, before the native clock driver
was added.  This was acked by the clk subsystem for going through our
tree as well.

This does make us pull quite a lot of changes, how about I just
cherry-pick "ARM: dts: bcm283x: Add 32-bit enable method for SMP" such
that the branch in itself is functional as-is, but we don't pull in
everything else from devicetree/next?

Then you get the commit duplicated in the history, which people
generally dislike even more.  Also, it depends on the arm64->arm move,
so you'd need that as well.
