| 2 | |
| 3 | The Broadcom STB wake-up timer provides a 27Mhz resolution timer, with the |
| 4 | ability to wake up the system from low-power suspend/standby modes. |
| 5 | |
| 6 | Required properties: |
| 7 | - compatible : should contain "brcm,brcmstb-waketimer" |
| 8 | - reg : the register start and length for the WKTMR block |
| 9 | - interrupts : The TIMER interrupt |
| 10 | - interrupt-parent: The phandle to the Always-On (AON) Power Management (PM) L2 |
| 11 | interrupt controller node |
| 12 | - clocks : The phandle to the UPG fixed clock (27Mhz domain) |
| 13 | |
| 14 | Example: |
| 15 | |
| 16 | waketimer@f0411580 { |
| 17 | compatible = "brcm,brcmstb-waketimer"; |
| 18 | reg = <0xf0411580 0x14>; |
| 19 | interrupts = <0x3>; |
| 20 | interrupt-parent = <&aon_pm_l2_intc>; |
| 21 | clocks = <&upg_fixed>; |
| 22 | }; |
