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>;
};
