    PCI: keystone: Add TI Keystone PCIe driver · 0c4ffcfe
    Murali Karicheri authored
    The Keystone PCIe controller is based on v3.65 version of the Designware
    h/w.  Main differences are:
    
        1. No ATU support
        2. Legacy and MSI IRQ functions are implemented in application register
           space
        3. MSI interrupts are multiplexed over 8 IRQ lines to the Host side.
    
    All of the application register space handing code is organized into
    pci-keystone-dw.c and the functions are called from pci-keystone.c to
    implement PCI controller driver.  Also add necessary DT documentation and
    update the MAINTAINERS file for the driver.
