Merge tag 'cleanup-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc 

Pull ARM SoC cleanups from Arnd Bergmann:
 "These cleanup patches are mainly move stuff around and should all be
  harmless.  They are mainly split out so that other branches can be
  based on top to avoid conflicts.

  Notable changes are:

   - We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
     longer used (Uwe Kleine-König)
   - The Qualcomm MSM platform is split out into legacy mach-msm and
     new-style mach-qcom, to allow easier maintainance of the new
     hardware support without regressions (Kumar Gala)
   - A rework of some of the Kconfig logic to simplify multiplatform
     support (Rob Herring)
   - Samsung Exynos gets closer to supporting multiplatform (Sachin
     Kamat and others)
   - mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
   - at91 gains some common clock framework support (Alexandre Belloni,
     Jean-Jacques Hiblot and other French people)"

CSR SiRFSoC Reset Controller

======================================



Please also refer to reset.txt in this directory for common reset

controller binding usage.



Required properties:

- compatible: Should be "sirf,prima2-rstc" or "sirf,marco-rstc"

- reg: should be register base and length as documented in the

  datasheet

- #reset-cells: 1, see below



example:



rstc: reset-controller@88010000 {

	compatible = "sirf,prima2-rstc";

	reg = <0x88010000 0x1000>;

	#reset-cells = <1>;

};



Specifying reset lines connected to IP modules

==============================================



The reset controller(rstc) manages various reset sources. This module provides

reset signals for most blocks in system. Those device nodes should specify the

reset line on the rstc in their resets property, containing a phandle to the

rstc device node and a RESET_INDEX specifying which module to reset, as described

in reset.txt.



For SiRFSoC, RESET_INDEX is just reset_bit defined in SW_RST0 and SW_RST1 registers.

For modules whose rest_bit is in SW_RST0, its RESET_INDEX is 0~31. For modules whose

rest_bit is in SW_RST1, its RESET_INDEX is 32~63.



example:



vpp@90020000 {

	compatible = "sirf,prima2-vpp";

	reg = <0x90020000 0x10000>;

	interrupts = <31>;

	clocks = <&clks 35>;

	resets = <&rstc 6>;

};
