Hi all, This short series adds support for the PWREN GPIO to the Apple PCIe controller driver, and along the way fixes some GPIO handling issues which cropped up. Since the PWREN GPIO is provided by SMC which is a fairly high level driver, PCI can probe before it is ready. Worse, only some devices need PWREN, which can make the probe fail halfway through with some ports initialized and not others, which the driver cannot recover gracefully from. The second patch fixes this situation, so probe deferral works properly in these cases. The third patch adds PWREN support per se, and the first one is just related stuff I noticed while writing this.
