I doubt this platform_data is dra7 specific. I believe it's
the same PCI controller that has been in the omap variants for
years?

AFAIK, this only applies to DRA7. Sekhar/Kishon can confirm. I did take
a quick look at OMAP3/4/5 TRMs, and didn't find any. Neither did a grep
on current hwmod files other than DRA7. There's a DM81xx related PCI
clock domain, but don't see any corresponding driver/device for the same.

Like Suman, I do not know of any TI SoC that came off the OMAP mobile
business that has PCIe.

DM81xx has a PCIe (but no mainline driver). Both DM81xx and DRA7x use a
designware core. But, the glue layer (which is the subject of interest
here), is completely different. I looked at the DM81xx driver in TI
kernel[1] to confirm this.

OK thanks for checking.

I remember talking to Kishon about similarities between the DM81xx and
DRA7x PCIe subsystem and remember that he too mentioned that they are
quite different.

OK

For an IP like PCIeSS, its quite difficult to come-up with unique names
without using the name of the platform they first appeared in. Anyway,
the driver is already called "pci-dra7xx", so I guess there is no harm
in having that name in platform data as well. That in itself should not
preclude its use on other platforms later (although I agree having a
generic name would be ideal).

Yeah seems OK to me. I still have some PM runtime related questions
though.. Will reply to the related patch chunk though.
