Subject: [PATCH 0/3] Introduce reset driver for T-HEAD th1520 SoC
Date: Tue, 12 Sep 2023 02:49:11 +0000	[thread overview]
Message-ID: <20230912024914.3769440-1-k.son@samsung.com> (raw)
In-Reply-To: <CGME20230912024917epcas1p29a513dcf6019fb7c63275aa0e39b1c71@epcas1p2.samsung.com>

From: Kwanghoon Son <k.son@samsung.com>

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>;
			status = "okay";
		};
```
