Merge branch 'vexpress-clk-soc' of git://git.linaro.org/people/pawelmoll/linux into next/soc2 

From Pawel Moll <pawel.moll@arm.com>:

This reworks the generic support for versatile express, in part
as preparation for the arm64 version of it that can now share
more of the code.

The series is based on top of the clk tree from Mike Turquette.

ARM Versatile Express system registers

--------------------------------------



This is a system control registers block, providing multiple low level

platform functions like board detection and identification, software

interrupt generation, MMC and NOR Flash control etc.



Required node properties:

- compatible value : = "arm,vexpress,sysreg";

- reg : physical base address and the size of the registers window

- gpio-controller : specifies that the node is a GPIO controller

- #gpio-cells : size of the GPIO specifier, should be 2:

  - first cell is the pseudo-GPIO line number:

    0 - MMC CARDIN

    1 - MMC WPROT

    2 - NOR FLASH WPn

  - second cell can take standard GPIO flags (currently ignored).



Example:

	v2m_sysreg: sysreg@10000000 {

 		compatible = "arm,vexpress-sysreg";

 		reg = <0x10000000 0x1000>;

		gpio-controller;

		#gpio-cells = <2>;

 	};



This block also can also act a bridge to the platform's configuration

bus via "system control" interface, addressing devices with site number,

position in the board stack, config controller, function and device

numbers - see motherboard's TRM for more details.



The node describing a config device must refer to the sysreg node via

"arm,vexpress,config-bridge" phandle (can be also defined in the node's

parent) and relies on the board topology properties - see main vexpress

node documentation for more details. It must must also define the

following property:

- arm,vexpress-sysreg,func : must contain two cells:

  - first cell defines function number (eg. 1 for clock generator,

    2 for voltage regulators etc.)

  - device number (eg. osc 0, osc 1 etc.)



Example:

	mcc {

		arm,vexpress,config-bridge = <&v2m_sysreg>;



		osc@0 {

			compatible = "arm,vexpress-osc";

			arm,vexpress-sysreg,func = <1 0>;

		};

	};

Configuration infrastructure

----------------------------



The platform has an elaborated configuration system, consisting of

microcontrollers residing on the mother- and daughterboards known

as Motherboard/Daughterboard Configuration Controller (MCC and DCC).

The controllers are responsible for the platform initialization

(reset generation, flash programming, FPGA bitfiles loading etc.)

but also control clock generators, voltage regulators, gather

environmental data like temperature, power consumption etc. Even

the video output switch (FPGA) is controlled that way.



Nodes describing devices controlled by this infrastructure should

point at the bridge device node:

- bridge phandle:

	arm,vexpress,config-bridge = <phandle>;

This property can be also defined in a parent node (eg. for a DCC)

and is effective for all children.





Platform topology

-----------------



As Versatile Express can be configured in number of physically

different setups, the device tree should describe platform topology.

Root node and main motherboard node must define the following

property, describing physical location of the children nodes:

- site number:

	arm,vexpress,site = <number>;

  where 0 means motherboard, 1 or 2 are daugtherboard sites,

  0xf means "master" site (site containing main CPU tile)

- when daughterboards are stacked on one site, their position

  in the stack be be described with:

	arm,vexpress,position = <number>;

- when describing tiles consisting more than one DCC, its number

  can be described with:

	arm,vexpress,dcc = <number>;



Any of the numbers above defaults to zero if not defined in

the node or any of its parent.

Current Linux implementation requires a "arm,v2m_timer" alias

pointing at one of the motherboard's SP804 timers, if it is to be

used as the system timer. This alias should be defined in the

motherboard files.

The tile description should define a "smb" node, describing the

Static Memory Bus between the tile and motherboard. It must define

the following properties:

- "simple-bus" compatible value (to ensure creation of the children)

	compatible = "simple-bus";

- mapping of the SMB CS/offset addresses into main address space:

	#address-cells = <2>;

	#size-cells = <1>;

	ranges = <...>;

- interrupts mapping:

	#interrupt-cells = <1>;

	interrupt-map-mask = <0 0 63>;

	interrupt-map = <...>;



The tile description must define "ranges", "interrupt-map-mask" and

"interrupt-map" properties to translate the motherboard's address

and interrupt space into one used by the tile's processor.
