Subject[RESEND PATCH v3 0/2] add new UniPhier PCIe host driver
This series adds PCIe host controller driver for Socionext UniPhier SoCs.
This controller is based on the DesignWare PCIe core. This driver
supports LD20 and PXs3 SoCs.


About legacy IRQ, it might be necessary to share common view from
keystone driver that have been cleaned up[1].


Changes since v2:
- dt-bindings: remove a comment that the node name isn't important
- dt-bindings: remove "intx" interrupt
- dt-bindings: define 'legacy-interrupt-controller' node and its properties
- return an error value when link up fails
- remove devm_request_irq() and a handler for MSI IRQ
- use chained interrupt instead of devm_request_irq() for legacy IRQ
- add unipher_pcie_config_legacy_irq() to get legacy IRQ from
'legacy-interrupt controller' node
- replace 4 statments to handle INTX with for_each_set_bit()
- remove initialization of pp->root_bus_nr
- remove indivisual interrupt enable bit definitions
- rename 'irq_domain' member to 'legacy_irq_domain' in private structure
- use pci_irqd_intx_xlate() for irq_domain_ops.xlate function

Changes since v1:
- follow capitalization conventions in the descriptions
- use C style comments except for the SPDX line
