+Broadcom STB wake-up Timer
+
+The Broadcom STB wake-up timer provides a 27Mhz resolution timer, with the
+ability to wake up the system from low-power suspend/standby modes.
+
+Required properties:
+- compatible : should contain "brcm,brcmstb-waketimer"
+- reg : the register start and length for the WKTMR block
+- interrupts : The TIMER interrupt
+- interrupt-parent: The phandle to the Always-On (AON) Power Management (PM) L2
+ interrupt controller node
+- clocks : The phandle to the UPG fixed clock (27Mhz domain)
+
+Example:
+
+waketimer@f0411580 {
+ compatible = "brcm,brcmstb-waketimer";
+ reg = <0xf0411580 0x14>;
+ interrupts = <0x3>;
+ interrupt-parent = <&aon_pm_l2_intc>;
+ clocks = <&upg_fixed>;

+* Faraday Technology FTRTC010 Real Time Clock
+
+This RTC appears in for example the Storlink Gemini family of
+SoCs.
+
+Required properties:
+- compatible : Should be one of:
+ "faraday,ftrtc010"
+ "cortina,gemini-rtc", "faraday,ftrtc010"
+
+Optional properties:
+- clocks: when present should contain clock references to the
+ PCLK and EXTCLK clocks. Faraday calls the later CLK1HZ and
+ says the clock should be 1 Hz, but implementers actually seem
+ to choose different clocks here, like Cortina who chose
+ 32768 Hz (a typical low-power clock).
+- clock-names: should name the clocks "PCLK" and "EXTCLK"
+ respectively.
+
+Examples:
+
+rtc@45000000 {
+ compatible = "cortina,gemini-rtc";
+ reg = <0x45000000 0x100>;
+ interrupts = <17 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&foo 0>, <&foo 1>;

+- clocks: can use up to two clocks, depending on part used:

- interrupt-parent: phandle for the interrupt controller.
- interrupts: rtc alarm interrupt.

(RTC registers) write protection.
-Optional properties (to override default ck_rtc parent clock):
