Add ATCWDT200 as reset device of AE350 platform, this driver requires SMU to program the reset vector registers before triggering WDT software restart signal. dts example: smu@f0100000 { compatible = "andestech,atcsmu"; reg = <0x00000000 0xf0100000 0x00000000 0x00001000>; }; wdt: wdt@f0500000 { compatible = "andestech,atcwdt200"; reg = <0x00000000 0xf0500000 0x00000000 0x00001000>; interrupts = <3 4>; interrupt-parent = <&plic0>; clock-frequency = <15000000>; }; Signed-off-by: Yu Chien Peter Lin <peterlin@andestech.com> Reviewed-by: Leo Yu-Chi Liang <ycliang@andestech.com> Reviewed-by: Anup Patel <anup@brainfault.org>
