Subject: [PATCH v2 2/7] Documentation: dt: Add binding info for jz4740-rtc driver
Date: Mon, 31 Oct 2016 00:02:42 +0100 [thread overview]
Message-ID: <20161030230247.20538-3-paul@crapouillou.net> (raw)
In-Reply-To: <20161030230247.20538-1-paul@crapouillou.net>
This commit adds documentation for the device-tree bindings of the
jz4740-rtc driver, which supports the RTC unit present in the JZ4740 and
JZ4780 SoCs from Ingenic.

+JZ4740 and similar SoCs real-time clock driver

+Required properties:
+
+- compatible: One of:
+ - "ingenic,jz4740-rtc" - for use with the JZ4740 SoC
+ - "ingenic,jz4780-rtc" - for use with the JZ4780 SoC
+- reg: Address range of rtc register set
+- interrupts: IRQ number for the alarm interrupt
+- clocks: phandle to the "rtc" clock
+- clock-names: must be "rtc"
+
+Optional properties:
+- system-power-controller: To use this component as the
+ system power controller
+- reset-pin-assert-time-msec: Reset pin low-level assertion
+ time after wakeup (default 60ms; range 0-125ms if RTC clock
+ at 32 kHz)
+- min-wakeup-pin-assert-time-msec: Minimum wakeup pin assertion
+ time (default 100ms; range 0-2s if RTC clock at 32 kHz)
+
+Example:
+
+rtc@10003000 {
+ compatible = "ingenic,jz4740-rtc";
+ reg = <0x10003000 0x3F>;
+
+ interrupt-parent = <&intc>;
+ interrupts = <32>;
+
+ clocks = <&rtc_clock>;
+ clock-names = "rtc";
+
+ system-power-controller;
+ reset-pin-assert-time-msec = <60>;
+ min-wakeup-pin-assert-time-msec = <100>;
