Merge remote-tracking branch 'tip/timers/core/timers/core' into clockevents/3.16

- clock-frequency : The frequency of the main counter, in Hz. Optional.

- always-on : a boolean property. If present, the timer is powered through an

  always-on power domain, therefore it never loses context.

Example:

	timer {

	interrupt-names = "macirq";

	mac-address = [00 00 00 00 00 00];/* Filled in by U-Boot */

	clocks = <&emac_0_clk>;

	clocks-names = "stmmaceth";

	clock-names = "stmmaceth";

};

- max-frame-size: See ethernet.txt file in the same directory

- clocks: If present, the first clock should be the GMAC main clock,

  further clocks may be specified in derived bindings.

- clocks-names: One name for each entry in the clocks property, the

- clock-names: One name for each entry in the clocks property, the

  first one should be "stmmaceth".

Examples:

		reg 		= <0xfe61f080 0x4>;

		reg-names	= "irqmux";

		interrupts 	= <GIC_SPI 180 IRQ_TYPE_LEVEL_HIGH>;

		interrupts-names = "irqmux";

		interrupt-names	= "irqmux";

		ranges 		= <0 0xfe610000 0x5000>;
