The RZ/G3E WDT IP is similar to RZ/V2H WDT. WDT0 can be used for CM33 cold
reset, system reset and asserting WDTUDFCM pin where as WDT1 can be used
for CA55 cold reset, system reset and asserting WDTUDFCA pin. Other 2
watchdogs can be used for system reset. So define WDT{1..3} in SoC dtsi.

  dt-bindings: watchdog: renesas,wdt: Document RZ/G3E support
  clk: renesas: r9a09g047: Add WDT clocks/resets
  watchdog: Make RZV2HWDT driver depend on ARCH_R9A09G47
  arm64: dts: renesas: r9a09g047: Add WDT1-WDT3 nodes
  arm64: dts: renesas: r9a09g047e57-smarc: Enable watchdog
