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. Changes from v1: *) remove phy_reset in the cleanup PHY handling patch. It will be sent while adding AM654 support *) Add a separate patch for using ERR_IRQ_STATUS instead of ERR_IRQ_STATUS_RAW *) Split outbound window configuration into two patches. One which gets the number of outbound windows from DT and the other cleansup outbound window configuration.
