-- clocks : AXI bus clock for the device. Refer to common clock bindings.
- Used to calculate MDIO clock divisor. If not specified, it is

+- clock-names: Tuple listing input clock names. Possible clocks:
+ s_axi_lite_clk: Clock for AXI register slave interface
+ axis_clk: AXI4-Stream clock for TXD RXD TXC and RXS interfaces
+ ref_clk: Ethernet reference clock, used by signal delay
+ primitives and transceivers
+ mgt_clk: MGT reference clock (used by optional internal
+ PCS/PMA PHY)

+ Note that if s_axi_lite_clk is not specified by name, the
+ first clock of any name is used for this. If that is also not
+ specified, the clock rate is auto-detected from the CPU clock
+ (but only on platforms where this is possible). New device
