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>;

};
