Subject: [RFC PATCH 0/3] Introduce reset driver for T-HEAD th1520 SoC
Date: Mon, 4 Sep 2023 04:25:56 +0000 [thread overview]
Message-ID: <20230904042559.2322997-1-k.son@samsung.com> (raw)
In-Reply-To: <CGME20230904042603epcas1p40f732a0ac7871371126d229945cc0849@epcas1p4.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 = "disabled";
};
```
