Merge branch 'x86/urgent' into x86/platform, to queue up dependent patch

clock-output-names:

 - "xin24m" - crystal input - required,

 - "ext_i2s" - external I2S clock - optional,

 - "ext_gmac" - external GMAC clock - optional

 - "rmii_clkin" - external EMAC clock - optional

Example: Clock controller node:

		1 = edge triggered

		4 = level triggered

  Cells 4 and beyond are reserved for future use. When the 1st cell

  has a value of 0 or 1, cells 4 and beyond act as padding, and may be

  ignored. It is recommended that padding cells have a value of 0.

  Cells 4 and beyond are reserved for future use and must have a value

  of 0 if present.

- reg : Specifies base physical address(s) and size of the GIC

  registers, in the following order:

  interrupt number is the rtc alarm interrupt and second interrupt number

  is the rtc tick interrupt. The number of cells representing a interrupt

  depends on the parent interrupt controller.

- clocks: Must contain a list of phandle and clock specifier for the rtc

          and source clocks.

- clock-names: Must contain "rtc" and "rtc_src" entries sorted in the

               same order as the clocks property.

Example:

		compatible = "samsung,s3c6410-rtc";

		reg = <0x10070000 0x100>;

		interrupts = <44 0 45 0>;

		clocks = <&clock CLK_RTC>, <&s2mps11_osc S2MPS11_CLK_AP>;

		clock-names = "rtc", "rtc_src";

	};

- fsl,uart-has-rtscts : Indicate the uart has rts and cts

- fsl,irda-mode : Indicate the uart supports irda mode

- fsl,dte-mode : Indicate the uart works in DTE mode. The uart works

                  is DCE mode by default.

                  in DCE mode by default.

Note: Each uart controller should have an alias correctly numbered

in "aliases" node.

efivarfs is typically mounted like this,

	mount -t efivarfs none /sys/firmware/efi/efivars

Due to the presence of numerous firmware bugs where removing non-standard

UEFI variables causes the system firmware to fail to POST, efivarfs

files that are not well-known standardized variables are created

as immutable files.  This doesn't prevent removal - "chattr -i" will work -

but it does prevent this kind of failure from being accomplished

accidentally.
