Merge tag 'dt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC DT updates from Olof Johansson:
 "DT and DT-conversion-related changes for various ARM platforms.  Most
  of these are to enable various devices on various boards, etc, and not
  necessarily worth enumerating.

  New boards and systems continue to come in as new devicetree files
  that don't require corresponding C changes any more, which is
  indicating that the system is starting to work fairly well.

  A few things worth pointing out:

   * ST Ericsson ux500 platforms have made the major push to move over
     to fully support the platform with DT
   * Renesas platforms continue their conversion over from legacy
     platform devices to DT-based for hardware description"

i: Local Timer Interrupt n
Example 1: In this example, the system uses only the first global timer
interrupt generated by MCT and the remaining three global timer
interrupts are unused. Two local timer interrupts have been
specified.
For MCT block that uses a per-processor interrupt for local timers, such
as ones compatible with "samsung,exynos4412-mct", only one local timer
interrupt might be specified, meaning that all local timers use the same
per processor interrupt.
Example 1: In this example, the IP contains two local timers, using separate
interrupts, so two local timer interrupts have been specified,
in addition to four global timer interrupts.
mct@10050000 {
compatible = "samsung,exynos4210-mct";
reg = <0x10050000 0x800>;
interrupts = <0 57 0>, <0 0 0>, <0 0 0>, <0 0 0>,
interrupts = <0 57 0>, <0 69 0>, <0 70 0>, <0 71 0>,
<0 42 0>, <0 48 0>;
};
Example 2: In this example, the MCT global and local timer interrupts are
connected to two separate interrupt controllers. Hence, an
interrupt-map is created to map the interrupts to the respective
interrupt controllers.

};
Example 3: In this example, the IP contains four local timers, but using
a per-processor interrupt to handle them. Either all the local
timer interrupts can be specified, with the same interrupt specifier
value or just the first one.

compatible = "samsung,exynos4412-mct";
