1NVIDIA Tegra210 timer
2
3The Tegra210 timer provides fourteen 29-bit timer counters and one 32-bit
4timestamp counter. The TMRs run at either a fixed 1 MHz clock rate derived
5from the oscillator clock (TMR0-TMR9) or directly at the oscillator clock
6(TMR10-TMR13). Each TMR can be programmed to generate one-shot, periodic,
7or watchdog interrupts.

9Required properties:
10- compatible : "nvidia,tegra210-timer".
11- reg : Specifies base physical address and size of the registers.
12- interrupts : A list of 14 interrupts; one per each timer channels 0 through
13  13.
14- clocks : Must contain one entry, for the module clock.
15  See ../clocks/clock-bindings.txt for details.
