The Tegra210 timer provides fourteen 29-bit timer counters and one 32-bit timestamp counter. The TMRs run at either a fixed 1 MHz clock rate derived from the oscillator clock (TMR0-TMR9) or directly at the oscillator clock (TMR10-TMR13). Each TMR can be programmed to generate one-shot periodic, or watchdog interrupts.

NVIDIA Tegra210 timer
|

|
|
The Tegra210 timer provides fourteen 29-bit timer counters and one 32-bit
|
|
timestamp counter. The TMRs run at either a fixed 1 MHz clock rate derived
|
|
from the oscillator clock (TMR0-TMR9) or directly at the oscillator clock
|
|
(TMR10-TMR13). Each TMR can be programmed to generate one-shot, periodic,
|
|
or watchdog interrupts.
|
|
|
|
Required properties:
|
|
- compatible : "nvidia,tegra210-timer".
|
|
- reg : Specifies base physical address and size of the registers.
|
|
- interrupts : A list of 14 interrupts; one per each timer channels 0 through
|
|
13.
|
|
- clocks : Must contain one entry, for the module clock.
|
|
See ../clocks/clock-bindings.txt for details.
