Since I am planning to move 'mt7621-pci' from staging to 'drivers/pci/controller' and send v3 after the next merge window, I prefer this patch to go through the staging tree. For the other two I don't have any preference and it is ok for me to go through mips or pci trees. So, Bjorn and Thomas is up to you if you are ok with the changes. Thanks in advance for your time. Best regards, Sergio Paracuellos

Yes, I would need acks for the other patches in the series if this is to come through the staging tree. thanks, greg k-h

Please submit patch 2 to the PCI developers and maintainer, as that is up to them to take, not me. thanks, greg k-h

Only one concern here, only with those two patches applied the driver is totally broken since it needs the remaining PATCH to make all the pci subsystem work. Is this ok?

Get the change acked by the PCI developers and I will be glad to also take it through my tree :)

We have increase IO_SPACE_LIMIT for ralink platform to get PCI IO resources properly handled using PCI core APIs. To align those changes with driver code we have to set 'ioport_resource' end limit to IO_SPACE_LIMIT to avoid errors.
