PCI: keystone: Assume controller is already in RC mode
Keystone PCI hardware supports both RC and EP modes and devcfg register has bits to boot strap the device to either of these modes. It seems proper to add this functionality to the boot loader rather than in the driver as device will be operating in either mode, not both any time. Currently the driver supports only RC mode and hence register configuration in the driver is not needed and the driver can assume the hardware is in RC mode. Also update the DT documentation accordingly. Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Arnd Bergmann <arnd@arndb.de>
