Although I give R-b, there is an idea just come out in my mind that this
might break OS distribution that use firmware(e.g. U-Boot) to publish
device tree for Linux Kernel, such as ARM System-Ready complaint OS.
I overlooked this point in previous patchset reviewing.
Since this patchset is to move anatop stuff to a new driver to reflect
the HW truth. And requires new entries in CCM node, so old bootloader
with new kernel will not boot for OS distribution, such as Fedora/openSuse.
Not sure how to keep backwards support as before. Leave to maintainers
to say if they are ok with this.

Peng
