This patchset adds initial support for reset driver. Register information is from vendor kernel [1]. I sent an e-mail to get permission the original author, but there was no answer. So I upload patch since it has GPL license.
This patch also can be tested with watchdog simply with
watchdog0: watchdog@ffefc30000 { compatible = "snps,dw-wdt"; reg = <0xff 0xefc30000 0x0 0x1000>; interrupts = <24 IRQ_TYPE_LEVEL_HIGH>; clocks = <&osc>; resets = <&rst TH1520_RESET_WDT0>; };
