Stephen Warren d8f64797c5 ARM: tegra: add missing clock documentation to DT bindings
Many of the Tegra DT binding documents say nothing about the clocks or
clock-names properties, yet those are present and required in DT files.
This patch simply updates the documentation file to match the implicit
definition of the binding, based on real-world DT content.

All Tegra bindings that mention clocks are updated to have consistent
wording and formatting of the clock-related properties.

NVIDIA Tegra20 timer
The Tegra20 timer provides four 29-bit timer channels and a single 32-bit free
running counter. The first two channels may also trigger a watchdog reset.
Required properties:
- compatible : should be "nvidia,tegra20-timer".
- reg : Specifies base physical address and size of the registers.
- interrupts : A list of 4 interrupts; one per timer channel.
- clocks : Must contain one entry, for the module clock.
See ../clocks/clock-bindings.txt for details.
Example:
timer {
compatible = "nvidia,tegra20-timer";
reg = <0x60005000 0x60>;
interrupts = <0 0 0x04
0 1 0x04
0 41 0x04
0 42 0x04>;
clocks = <&tegra_car 132>;
};
