Merge tag 'tty-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty 

Pull tty/serial driver update from Greg KH:
 "Here's the big tty/serial driver update for 3.15-rc1.

  Nothing major, a number of serial driver updates and a few tty core
  fixes as well.

  All have been in linux-next for a while"

* Maxim MAX310X advanced Universal Asynchronous Receiver-Transmitter (UART)



Required properties:

- compatible: Should be one of the following:

  - "maxim,max3107" for Maxim MAX3107,

  - "maxim,max3108" for Maxim MAX3108,

  - "maxim,max3109" for Maxim MAX3109,

  - "maxim,max14830" for Maxim MAX14830.

- reg: SPI chip select number.

- interrupt-parent: The phandle for the interrupt controller that

  services interrupts for this IC.

- interrupts: Specifies the interrupt source of the parent interrupt

  controller. The format of the interrupt specifier depends on the

  parent interrupt controller.

- clocks: phandle to the IC source clock.

- clock-names: Should be "xtal" if clock is an external crystal or

  "osc" if an external clock source is used.



Optional properties:

- gpio-controller: Marks the device node as a GPIO controller.

- #gpio-cells: Should be two. The first cell is the GPIO number and

  the second cell is used to specify the GPIO polarity:

    0 = active high,

    1 = active low.



Example:

	max14830: max14830@0 {

		compatible = "maxim,max14830";

		reg = <0>;

		clocks = <&clk20m>;

		clock-names = "osc";
