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.
