This patch add a DT enabled driver for timers found on Marvell Orion SoCs (Kirkwood, Dove, Orion5x, and Discovery Innovation). It installs a free- running clocksource on timer0 and a clockevent source on timer1. Corresponding device tree documentation is also added.

Marvell Orion SoC timer
|
|
|
|
Required properties:
|
|
- compatible: shall be "marvell,orion-timer"
|
|
- reg: base address of the timer register starting with TIMERS CONTROL register
|
|
- interrupt-parent: phandle of the bridge interrupt controller
|
|
- interrupts: should contain the interrupts for Timer0 and Timer1
|
|
- clocks: phandle of timer reference clock (tclk)
|
|
|
|
Example:
|
|
timer: timer {
|
|
compatible = "marvell,orion-timer";
|
|
reg = <0x20300 0x20>;
|
|
interrupt-parent = <&bridge_intc>;
|
|
interrupts = <1>, <2>;
|
|
clocks = <&core_clk 0>;
|
|
};
