[PATCH 0/3] PCIe link change improvements
everything was taken from nvgpu.
Main reason for adding is to improve stability of the PCIe link changing code
as we might want to depend on it for a workaround fixing our infamous runpm
issues on recent laptops

[PATCH v4 0/4] add PCIe workaround to fix runpm on laptops
not much changed since the last time I sent those patches out, but there
are a couple of annoying bug fixes, which users would probably never hit
unless they do rmmod/modprobe nouveau cycles.
Biggest change is that I force the link to a 8.0 speed rather than the
speed the GPU came up with.
Also this series depends on the PCIe improvement patches I sent out
recently.

[PATCH 0/6] Add workaround for fixing runpm
I merged the both series I sent out recently into one bigger one so that
it's more obvious on why all of that is needed.
Biggest changes since last sent:
* reworked the ASPM patch
* removed "pci: add nvkm_pcie_get_speed" patch
Please test this on Laptops and report back if it either breaks something
or doesn't fix runpm.
Thanks

[PATCH 0/8] Add workaround for fixing runpm
Changes since last sent:
* add a patch to set the device into DRM_SWITCH_POWER_CHANGING state
(can be dropped actually, I thought I was needing it, came up with a
different approach and forgot to delete it, doesn't hurt though)
* expose information about runtime suspending to nvkm so that we can run
the pcie workaround only on runtime suspend
