-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
-- 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>;
-};
