jesd204: Intel: NP12 support Dual clock mode is introduced in link layer to support different datapath widths on the transport layer than on physical layer. - Link clock : lane rate / 40 for input datapath width of 4 octets 8b10b - Device clock : Link clock * input data path width / output datapath width Supports four clock configurations, single or dual clock mode with or without external device clock. The configuration interface reflects the dual clock domain.
