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. v1->v2: * Dropped patch#2, #4 and #5 as it is queued for renesas_clk and renesas_devel. * Collected tags for patch#1. * Updated commit header and description for patch#2. * Replaced ARCH_R9A09G047->ARCH_RENESAS as both RZ/V2H and RZ/G3E belongs to ARCH_RENESAS family.
