The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Use of_get_cpu_hwid() rather than the open coded reading of the CPU
nodes "reg" property. The existing code is in fact wrong as the "reg"
address cells size is 2 cells for arm64. The existing code happens to
work because the DTS files are wrong as well.

If we exit the for_each_of_cpu_node loop early, the reference on the
current node must be decremented, otherwise there is a leak.

Not much effort has been put into this one.
Demote it for the time being at least.

There are a few manually-calculated variable-length struct allocations
left, this converts them to use struct_size. Found with the following
git grep command
git grep -A1 'kzalloc.*sizeof[^_].*+'

This patch allows same flow to be executed on chips with different
register mappings like AP806 and, in the future, AP807.
Note: this patch has no functional effect, and only prepares the
driver for additional chips to be supported by retrieving the right
device data depenging on the compatible property.

The CPU frequency is managed at the AP level for the Armada 7K/8K. The
CPU frequency is modified by cluster: the CPUs of the same cluster have
the same frequency.
This patch adds the clock driver that will be used by CPUFreq, it is
based on the work of Omri Itach <omrii@marvell.com>.
