This series tries to address the comments discussed in [1] w.r.t removing Keystone specific callbacks defined in dw_pcie_host_ops. This series also tries to cleanup the Keystone interrupt handling part. Changes from v2: *) Removed patch that modifies ks_pcie_legacy_irq_handler() to check the IRQ_STATUS of INTA/B/C/D. Lorenzo's comment to create a matrix LinuxIRQ x INTx will be added in AM654x PCIe support series *) ks_pcie_legacy_irq_handler() is made to use hwirq to get IRQ offset instead of virq. *) default msi_irq_chip is assigned in dw_pcie_host_init() once keystone assigns its msi_irq_chip *) Fixed other minor comments from Lorenzo and Bjorn Changes from v1: *) Removed "PCI: keystone: Use "dummy_irq_chip" instead of new irqchip for legacy interrupt handling" from the patch series. It should be handled differently. *) Added Gustavo's ACKed by and fixed a commit message.
