ARM: tegra: define DT bindings for and instantiate RTC The Tegra RTC maintains seconds and milliseconds counters, and five alarm registers. The alarms and other interrupts may wake the system from low-power state. Define a DT binding for this HW module, and add the module into the Tegra device tree files.

NVIDIA Tegra20 real-time clock
The Tegra RTC maintains seconds and milliseconds counters, and five alarm
registers. The alarms and other interrupts may wake the system from low-power
state.
Required properties:
- compatible : should be "nvidia,tegra20-rtc".
- reg : Specifies base physical address and size of the registers.
- interrupts : A single interrupt specifier.
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.

- clocks : Must contain one entry, for the module clock.
See ../clocks/clock-bindings.txt for details.

Example:
timer {
compatible = "nvidia,tegra20-rtc";
reg = <0x7000e000 0x100>;
interrupts = <0 2 0x04>;
