Subject: [PATCH V7 1/8] dt-bindings: timer: add 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.

+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.
