Subject: [PATCH 03/11] watchdog: Add brcm,bcm6345-wdt device tree binding
Date: Tue, 1 Dec 2015 13:03:47 +0000 [thread overview]
Message-ID: <565D9AB3.2060504@simon.arlott.org.uk> (raw)
In-Reply-To: <565D9A40.60409@simon.arlott.org.uk>
Add device tree binding for the BCM6345 watchdog.
This uses the BCM6345 timer for its warning interrupt.
Signed-off-by: Simon Arlott <simon@fire.lp0.eu>
Acked-by: Rob Herring <robh@kernel.org>

+BCM6345 Watchdog timer
+
+Required properties:
+
+- compatible: should be "brcm,bcm63<soc>-wdt", "brcm,bcm6345-wdt"
+- reg: Specifies base physical address and size of the registers.
+- clocks: Specify the clock used for timing
+
+Optional properties:
+
+- interrupt-parent: phandle to the interrupt controller
+- interrupts: Specify the interrupt used for the watchdog timout warning
+- timeout-sec: Contains the default watchdog timeout in seconds
+
+Example:
+
+watchdog {
+ compatible = "brcm,bcm63168-wdt", "brcm,bcm6345-wdt";
+ reg = <0x1000009c 0x0c>;
+ clocks = <&periph_clk>;
+
+ interrupt-parent = <&timer>;
+ interrupts = <3>;
+ timeout-sec = <30>;
+};
+
+watchdog {
+ compatible = "brcm,bcm6318-wdt", "brcm,bcm6345-wdt";
+ reg = <0x10000068 0x0c>;
+ clocks = <&periph_clk>;
+
+ interrupt-parent = <&timer>;
+ interrupts = <3>;
+ timeout-sec = <30>;
