* Freescale MPIC timers
|
|
|
|
Required properties:
|
|
- compatible: "fsl,mpic-global-timer"
|
|
|
|
- reg : Contains two regions. The first is the main timer register bank
|
|
(GTCCRxx, GTBCRxx, GTVPRxx, GTDRxx). The second is the timer control
|
|
register (TCRx) for the group.
|
|
|
|
- fsl,available-ranges: use <start count> style section to define which
|
|
timer interrupts can be used. This property is optional; without this,
|
|
all timers within the group can be used.
|
|
|
|
- interrupts: one interrupt per timer in the group, in order, starting
|
|
with timer zero. If timer-available-ranges is present, only the
|
|
interrupts that correspond to available timers shall be present.
|
|
|
|
Example:
|
|
/* Note that this requires #interrupt-cells to be 4 */
|
|
timer0: timer@41100 {
|
|
compatible = "fsl,mpic-global-timer";
|
|
reg = <0x41100 0x100 0x41300 4>;
|
|
|
|
/* Another AMP partition is using timers 0 and 1 */
|
|
fsl,available-ranges = <2 2>;
|
|
|
|
interrupts = <2 0 3 0
|
|
3 0 3 0>;
|
|
};
|
|
|
|
timer1: timer@42100 {
|
|
compatible = "fsl,mpic-global-timer";
|
|
reg = <0x42100 0x100 0x42300 4>;
|
|
interrupts = <4 0 3 0
|
|
5 0 3 0
|
|
6 0 3 0
|
|
7 0 3 0>;
|
|
};
