[PATCH v4 1/4] dt-bindings: rtc: add bindings for i.MX53 SRTC

[linux-kernel-dev at beckhoff.com]

From: Patrick Bruenn <p.bruenn at beckhoff.com>

Document the binding for i.MX53 SRTC implemented by rtc-mxc_v2

Signed-off-by: Patrick Bruenn <p.bruenn at beckhoff.com>

v4:
- replace "srtc" node name with generic "rtc"

v2:
- added "Secure" and (SRTC) to the description

+* i.MX53 Secure Real Time Clock (SRTC)
+
+Required properties:
+- compatible: should be: "fsl,imx53-rtc"
+- reg: physical base address of the controller and length of memory mapped
+  region.
+- clocks: should contain the phandle for the rtc clock
+- interrupts: rtc alarm interrupt
+
+Example:
+
+rtc at 53fa4000 {
+	compatible = "fsl,imx53-rtc";
+	reg = <0x53fa4000 0x4000>;
+	interrupts = <24>;
+	clocks = <&clks IMX5_CLK_SRTC_GATE>;
+};
