7 title: Freescale Layerscape PCIe Endpoint(EP) controller
10 - Frank Li <Frank.Li@nxp.com>
13 This PCIe EP controller is based on the Synopsys DesignWare PCIe IP.
15 This controller derives its clocks from the Reset Configuration Word (RCW)
16 which is used to describe the PLL settings at the time of chip-reset.
18 Also as per the available Reference Manuals, there is no specific 'version'
19 register available in the Freescale PCIe controller register set,
20 which can allow determining the underlying DesignWare PCIe controller version
