This is an series of mixed improvements to the DRA7 PCI controller driver:
allow building as a loadabel module, allow to get and enable a clock and a
small cleanup.

Luca Ceresoli (5):
  PCI: dwc: export more symbols to allow modular drivers
  PCI: dwc: pci-dra7xx: make it a kernel module
  PCI: dwc: pci-dra7xx: allow to build as a loadable module
  PCI: dwc: pci-dra7xx: remove unused include
  PCI: dwc: pci-dra7xx: get an optional clock

This driver has a poor record of subject lines:

  PCI: pci-dra7xx: Prepare for deferred probe with module_platform_driver
  PCI: dwc: Move dw_pcie_setup_rc() to DWC common code
  PCI: dwc/dra7xx: Use the common MSI irq_chip
  PCI: dwc: pci-dra7xx: Fix runtime PM imbalance on error

The "PCI: dwc:" ones are fine -- they apply to the shared dwc core,
not specifically to dra7xx.

The driver-specific ones:

  PCI: pci-dra7xx:
  PCI: dwc/dra7xx:
  PCI: dwc: pci-dra7xx:

are redundant and waste space.  There's no need to mention "dwc" for
dra7xx-specific things, and no need to mention "PCI" twice.

We should use the "PCI: dra7xx:" prefix for things specific to this
driver.

The rest of the subject line should start with a capital letter.  The
subject line should contain specific information when practical.  For
example,

  PCI: dwc: Export dw_pcie_link_up(), dw_pcie_ep_reset_bar() for modular drivers
  PCI: dra7xx: Allow building as module
  PCI: dra7xx: Remove unused linux/init.h include
  PCI: dra7xx: Get optional external clock

I would squash 2/5 and 3/5, similar to a98d2187efd9 ("PCI: meson:
Build as module by default") and 526a76991b7b ("PCI: aardvark:
Implement driver 'remove' function and allow to build it as module").

Thanks for the prompt review. I'll wait a few days for any more comments
and then resend.
