Hi Lorenzo / Bjorn,
Can you please review this series?
I have Reviewed-by and Acked-by from Rob, Thierry and Andrew already.

Thanks,

This patch series enables Tegra194's C5 controller which owns x16 slot in
p2972-0000 platform. C5 controller's PERST# and CLKREQ# are not configured as
output and bi-directional signals by default and hence they need to be
configured explicitly. Also, x16 slot's 3.3V and 12V supplies are controlled
through GPIOs and hence they need to be enabled through regulator framework.
This patch series adds required infrastructural support to address both the
aforementioned requirements.
Testing done on p2972-0000 platform
- Able to enumerate devices connected to x16 slot (owned by C5 controller)
- Enumerated device's functionality verified
- Suspend-Resume sequence is verified with device connected to x16 slot

V3:
* Addressed some more review comments from Andrew Murray and Thierry Reding

V2:
* Changed the order of patches in the series for easy merging
* Addressed review comments from Thierry Reding and Andrew Murray
