[PATCH V2 0/2] PCI: imx6: Improve PERST# fallback logic

["Sherry Sun (OSS)" <sherry.sun@oss.nxp.com>]

From: Sherry Sun <sherry.sun@nxp.com>

The pci_host_common_parse_port() shouldn't decide whether to fall back
to the legacy RC-level binding by checking for "reset-gpios/reset-gpio"
properties on the RC node and returning -ENODEV. That's a policy
decision belongs to the caller, not this common helper.

This patch set improves the PERST# (PCIe reset) GPIO fallback logic
across the generic PCI host bridge helper and the i.MX6 PCIe driver.
