[00/19] PCI: Cleanup pci-keystone driver

Message

Kishon Vijay Abraham I Oct. 15, 2018, 1:07 p.m. UTC

This series was sent as part of RFC series [1]

The PCIe controller in AM654 uses Synopsys core revision 4.90a and uses
the same TI wrapper as used in keystone2 with certain modification.
Hence AM654 will use the same pci wrapper driver pci-keystone.c

In preparation for adding AM654 support, cleanup pci-keystone driver
here.

Most of the cleanups here are trivial with major modification being
merging pci-keystone-dw.c and pci-keystone.c

Cleaning-up irq handling in the RFC series is dropped here as it has
few comments to be addressed.

Other patches which are part of the RFC series will be sent separately.
