[PATCH v1 0/2] PCI: microchip: support using either instance 1 or 2

[Conor Dooley]

The current driver and binding for PolarFire SoC's PCI controller assume
that the root port instance in use is instance 1. The second reg
property constitutes the region encompassing both "control" and "bridge"
registers for both instances. In the driver, a fixed offset is applied to
find the base addresses for instance 1's "control" and "bridge"
registers. The BeagleV Fire uses root port instance 2, so something must
be done so that software can differentiate. This series splits the
second reg property in two, with dedicated "control" and "bridge"
entries so that either instance can be used.

Cheers,
Conor.
