Hi,

This series adds support for SAMA7G5 Ethernet interfaces: one 10/100Mbps
and one 1Gbps interfaces.

Along with it I also included a fix to disable clocks for SiFive FU540-C000
on failure path of fu540_c000_clk_init().

Thank you,
Claudiu Beznea

  net: macb: add capability to not set the clock rate
  net: macb: unprepare clocks in case of failure
  dt-bindings: add documentation for sama7g5 ethernet interface
  dt-bindings: add documentation for sama7g5 gigabit ethernet interface
