PCI: Collect all native drivers under drivers/pci/controller/

2018-06-08T12:50:11Z

Native PCI drivers for root complex devices were originally all in drivers/pci/host/. Some of these devices can also be operated in endpoint mode. Drivers for endpoint mode didn't seem to fit in the "host" directory, so we put both the root complex and endpoint drivers in per-device directories, e.g., drivers/pci/dwc/, drivers/pci/cadence/, etc. These per-device directories contain trivial Kconfig and Makefiles and clutter drivers/pci/. Make a new drivers/pci/controllers/ directory and collect all the device-specific drivers there. No functional change intended.

When CONFIG_GPIOLIB is disabled, we run into a build failure: drivers/pci/dwc/pcie-qcom.c: In function 'qcom_pcie_probe': drivers/pci/dwc/pcie-qcom.c:1223:16: error: implicit declaration of function 'devm_gpiod_get_optional'; did you mean 'devm_regulator_get_optional'? [-Werror=implicit-function-declaration] pcie->reset = devm_gpiod_get_optional(dev, "perst", GPIOD_OUT_LOW); Including gpio/consumer.h directly is the correct fix.

PCI: Rework of_pci_get_host_bridge_resources() to devm_of_pci_get_host_bridge_resources()

2018-05-30T16:35:13Z

of_pci_get_host_bridge_resources() allocates the resource structures it fills dynamically, but none of its callers care to release them so far. Rather than requiring everyone to do this explicitly, convert the existing function to a managed version.

PCI: Pass struct device to of_pci_get_host_bridge_resources()

2018-05-30T16:34:56Z

Another step towards a managed version of of_pci_get_host_bridge_resources(): Feed in the underlying device, rather than just the OF node. This will allow us to use managed resource allocation internally later on.
