Document the Ethernet AVB IP found on RZ/V2M SoC. It includes the Ethernet controller (E-MAC) and Dedicated Direct memory access controller (DMAC) for transferring transmitted Ethernet frames to and received Ethernet frames from respective storage areas in the RAM at high speed. The AVB-DMAC is compliant with IEEE 802.1BA, IEEE 802.1AS timing and synchronization protocol, IEEE 802.1Qav real-time transfer, and the IEEE 802.1Qat stream reservation protocol. R-Car has a pair of combined interrupt lines: ch22 = Line0_DiA | Line1_A | Line2_A ch23 = Line0_DiB | Line1_B | Line2_B Line0 for descriptor interrupts (which we call dia and dib). Line1 for error related interrupts (which we call err_a and err_b). Line2 for management and gPTP related interrupts (mgmt_a and mgmt_b). RZ/V2M hardware has separate interrupt lines for each of these. It has 3 clocks; the main AXI clock, the AMBA CHI (Coherent Hub Interface) clock and a gPTP reference clock.
