+Motorola CPCAP PMIC RTC
+-----------------------
+
+This module is part of the CPCAP. For more details about the whole
+chip see Documentation/devicetree/bindings/mfd/motorola-cpcap.txt.
+
+Requires node properties:
+- compatible: should contain "motorola,cpcap-rtc"
+- interrupts: An interrupt specifier for alarm and 1 Hz irq
+
+Example:
+
+&cpcap {
+ cpcap_rtc: rtc {
+ compatible = "motorola,cpcap-rtc";
+ interrupts = <39 IRQ_TYPE_NONE>, <26 IRQ_TYPE_NONE>;
+ };
+};

+* Real Time Clock for Renesas SH and ARM SoCs
+
+Required properties:
+- compatible: Should be "renesas,r7s72100-rtc" and "renesas,sh-rtc" as a
+ fallback.
+- reg: physical base address and length of memory mapped region.
+- interrupts: 3 interrupts for alarm, period, and carry.
+- interrupt-names: The interrupts should be labeled as "alarm", "period", and
+ "carry".
+- clocks: The functional clock source for the RTC controller must be listed
+ first (if exists). Additionally, potential clock counting sources are to be
+ listed.
+- clock-names: The functional clock must be labeled as "fck". Other clocks
+ may be named in accordance to the SoC hardware manuals.
+
+
+Example:
+rtc: rtc@fcff1000 {
+ compatible = "renesas,r7s72100-rtc", "renesas,sh-rtc";
+ reg = <0xfcff1000 0x2e>;
+ interrupts = <GIC_SPI 276 IRQ_TYPE_EDGE_RISING
+ GIC_SPI 277 IRQ_TYPE_EDGE_RISING
+ GIC_SPI 278 IRQ_TYPE_EDGE_RISING>;
+ interrupt-names = "alarm", "period", "carry";
+ clocks = <&mstp6_clks R7S72100_CLK_RTC>, <&rtc_x1_clk>,
+ <&rtc_x3_clk>, <&extal_clk>;
+ clock-names = "fck", "rtc_x1", "rtc_x3", "extal";
+};
