[PATCH 0/3] arm64: Realtek RTD1295 watchdog

[Andreas Färber]

Hello,

This series adds the watchdog for the Realtek RTD1295 SoC.

There being no public source code for RTD1295, the implementation is based on
register offsets seen in the vendor DT, as well as older mach-rtk119x code
published by QNAP.

The DT node depends on my RTD1295 clk series.

More experimental patches at:
https://github.com/afaerber/linux/commits/rtd1295-next

Have a lot of fun!

Cheers,
Andreas

+Realtek RTD1295 Watchdog
+========================
+
+Required properties:
+
+- compatible :  Should be "realtek,rtd1295-watchdog"
+- reg        :  Specifies the physical base address and size of registers
+- clocks     :  Specifies one clock input
+
+
+Example:
+
+	watchdog@98007680 {
+		compatible = "realtek,rtd1295-watchdog";
+		reg = <0x98007680 0x100>;
+		clocks = <&osc27M>;
