Hi,
This is v4 of the series to add support for TI-SCI Generic PM Domains.
Previous versions can be found here:

v3: https://www.spinics.net/lists/kernel/msg2413975.html
v2: https://www.spinics.net/lists/kernel/msg2364612.html

After much debate I have returned to using the phandle cell to pass the SCI ID
rather than the separate "ti,sci-id" property that was not very popular. In
order to do this I needed to make a change to the genpd framework which can be
seen in patch 2 and should benefit others that have client . Rather than
checking for zero phandle args and failing if any are present the
of_genpd_add_provider_simple call does not check at all and instead leaves
parsing and interpretation up to the platform genpd driver.

This allows the ti_sci_pm_domains driver to parse the phandle and use the first
phandle cell as the sci-id rather than getting it from a separate property.

Besides that none of the original patches have changed apart from updating the
year to 2017 in patches 3 and 4 and of course a small update to patch 4 to let
the ti_sci_pm_domains parse the phandle and extract the sci-id rather than
looking for the rejected ti,sci-id property.

I did not update the "power-domain" binding document because in regards to
#power-domain-cells it already states "can be any value as specified by device
tree binding documentation of particular provider" which I think already
describes the change in patch 2.
I'm assuming that this will go in through the arm-soc tree.

Thanks,
Rafael
