Merge branch 'pci/host/dwc'
- Export dw_pcie_ep_reset_bar(), dw_pcie_link_up() so more drivers can be
modular (Luca Ceresoli)
- Allow dra7xx host and endpoint drivers to be modules (Luca Ceresoli)
- Enable dra7xx optional external clock if present (Luca Ceresoli)
- Clean up Kconfig dependencies for PCIE_DW_HOST- and PCIE_DW_EP-based
drivers (Andy Shevchenko)
- Remove visconti redundant dev_err() after platform_get_irq_byname()
failure (Krzysztof WilczyĆski)
- Run dwc .host_init() method before registering MSI interrupt handler so
we have a chance to deal with pending interrupts left by bootloader
(Bjorn Andersson)
- Serialize uniphier INTx masking/unmasking (Kunihiko Hayashi)
* pci/host/dwc:
PCI: uniphier: Serialize INTx masking/unmasking and fix the bit operation
PCI: dwc: Perform host_init() before registering msi
PCI: visconti: Remove surplus dev_err() when using platform_get_irq_byname()
PCI: dwc: Clean up Kconfig dependencies (PCIE_DW_EP)
PCI: dwc: Clean up Kconfig dependencies (PCIE_DW_HOST)
PCI: dra7xx: Get an optional clock
PCI: dra7xx: Remove unused include
PCI: dra7xx: Make it a kernel module
PCI: dwc: Export more symbols to allow modular drivers
