Hi,
This patch series should mostly be self-descriptive, but it's motivated by the
fact that I've found differing requirements from PCIe endpoint makers regarding
the state of PERST# when in system suspend (S3). Additionally, some existing
boards are not especially well suited for holding PERST# low in S3 (e.g., the
pin is driven by a non-PMU GPIO, so it's hard or impossible to keep it
asserted). So the solution is...give it a device tree property!
