ARM SoC specific changes 

These changes are all to SoC-specific code, a total of 33 branches on
 17 platforms were pulled into this. Like last time, Renesas sh-mobile
 is now the platform with the most changes, followed by OMAP and EXYNOS.
 
 Two new platforms, TI Keystone and Rockchips RK3xxx are added in
 this branch, both containing almost no platform specific code at all,
 since they are using generic subsystem interfaces for clocks, pinctrl,
 interrupts etc. The device drivers are getting merged through the
 respective subsystem maintainer trees.
 
 One more SoC (u300) is now multiplatform capable and several others
 (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving
 towards that goal with this series but need more work.
 
 Also noteworthy is the work on PCI here, which is traditionally part of
 the SoC specific code. With the changes done by Thomas Petazzoni, we can
 now more easily have PCI host controller drivers as loadable modules and
 keep them separate from the platform code in drivers/pci/host. This has
 already led to the discovery that three platforms (exynos, spear and imx)
 are actually using an identical PCIe host controller and will be able
 to share a driver once support for spear and imx is added.
 
 Conflicts:
 * asm/glue-proc.h has one CPU type getting added that conflicts
   with another addition in 3.10-rc7
 * Simple context changes in arch/arm/Makefile and arch/arm/Kconfig

=======================================================
ARM CCI cache coherent interconnect binding description
=======================================================
ARM multi-cluster systems maintain intra-cluster coherency through a
cache coherent interconnect (CCI) that is capable of monitoring bus
transactions and manage coherency, TLB invalidations and memory barriers.
It allows snooping and distributed virtual memory message broadcast across
clusters, through memory mapped interface, with a global control register
space and multiple sets of interface control registers, one per slave
interface.
Bindings for the CCI node follow the ePAPR standard, available from:
www.power.org/documentation/epapr-version-1-1/
with the addition of the bindings described in this document which are
specific to ARM.
* CCI interconnect node
Description: Describes a CCI cache coherent Interconnect component
Node name must be "cci".
Node's parent must be the root node /, and the address space visible
through the CCI interconnect is the same as the one seen from the
root node (ie from CPUs perspective as per DT standard).
Every CCI node has to define the following properties:
- compatible
Usage: required
Value type: <string>
Definition: must be set to
"arm,cci-400"
- reg
Usage: required
Value type: <prop-encoded-array>
Definition: A standard property. Specifies base physical
address of CCI control registers common to all
interfaces.
- ranges:
Usage: required
Value type: <prop-encoded-array>
Definition: A standard property. Follow rules in the ePAPR for
hierarchical bus addressing. CCI interfaces
addresses refer to the parent node addressing
scheme to declare their register bases.
CCI interconnect node can define the following child nodes:
- CCI control interface nodes
Node name must be "slave-if".
Parent node must be CCI interconnect node.
A CCI control interface node must contain the following
properties:
- compatible
Usage: required
Value type: <string>
Definition: must be set to
"arm,cci-400-ctrl-if"
- interface-type:
Usage: required
Value type: <string>
Definition: must be set to one of {"ace", "ace-lite"}
depending on the interface type the node
represents.
- reg:
Usage: required
Value type: <prop-encoded-array>
Definition: the base address and size of the
corresponding interface programming
registers.
* CCI interconnect bus masters
Description: masters in the device tree connected to a CCI port
(inclusive of CPUs and their cpu nodes).
A CCI interconnect bus master node must contain the following
properties:
- cci-control-port:
Usage: required
Value type: <phandle>
Definition: a phandle containing the CCI control interface node
the master is connected to.
Example:
cpus {
#size-cells = <0>;
#address-cells = <1>;
CPU0: cpu@0 {
device_type = "cpu";
compatible = "arm,cortex-a15";
cci-control-port = <&cci_control1>;
reg = <0x0>;
};
CPU1: cpu@1 {
device_type = "cpu";
compatible = "arm,cortex-a15";
cci-control-port = <&cci_control1>;
reg = <0x1>;
};
CPU2: cpu@100 {
device_type = "cpu";
compatible = "arm,cortex-a7";
cci-control-port = <&cci_control2>;
reg = <0x100>;
};
CPU3: cpu@101 {
device_type = "cpu";
compatible = "arm,cortex-a7";
cci-control-port = <&cci_control2>;
reg = <0x101>;
};
};
dma0: dma@3000000 {
compatible = "arm,pl330", "arm,primecell";
cci-control-port = <&cci_control0>;
reg = <0x0 0x3000000 0x0 0x1000>;
interrupts = <10>;
#dma-cells = <1>;
#dma-channels = <8>;
#dma-requests = <32>;
};
cci@2c090000 {
compatible = "arm,cci-400";
#address-cells = <1>;
#size-cells = <1>;
reg = <0x0 0x2c090000 0 0x1000>;
ranges = <0x0 0x0 0x2c090000 0x6000>;
cci_control0: slave-if@1000 {
compatible = "arm,cci-400-ctrl-if";
interface-type = "ace-lite";
reg = <0x1000 0x1000>;
};
cci_control1: slave-if@4000 {
compatible = "arm,cci-400-ctrl-if";
interface-type = "ace";
reg = <0x4000 0x1000>;
};
cci_control2: slave-if@5000 {
compatible = "arm,cci-400-ctrl-if";
interface-type = "ace";
reg = <0x5000 0x1000>;
};
};
This CCI node corresponds to a CCI component whose control registers sits
at address 0x000000002c090000.
CCI slave interface @0x000000002c091000 is connected to dma controller dma0.
CCI slave interface @0x000000002c094000 is connected to CPUs {CPU0, CPU1};
CCI slave interface @0x000000002c095000 is connected to CPUs {CPU2, CPU3};

Used to describe the ARM_PLL, DDR_PLL, and IO_PLL.
== Clock Controller ==
The clock controller is a logical abstraction of Zynq's clock tree. It reads
required input clock frequencies from the devicetree and acts as clock provider
for all clock consumers of PS clocks.

- #clock-cells : shall be 0 (only one clock is output from this node)
- compatible : "xlnx,zynq-pll"
- reg : pair of u32 values, which are the address offsets within the SLCR
of the relevant PLL_CTRL register and PLL_CFG register respectively
- clocks : phandle for parent clock. should be the phandle for ps_clk
- #clock-cells : Must be 1
- compatible : "xlnx,ps7-clkc"
- ps-clk-frequency : Frequency of the oscillator providing ps_clk in HZ
(usually 33 MHz oscillators are used for Zynq platforms)
- clock-output-names : List of strings used to name the clock outputs. Shall be
a list of the outputs given below.
Optional properties:
- clock-output-names : name of the output clock
- clocks : as described in the clock bindings
- clock-names : as described in the clock bindings
Clock inputs:
The following strings are optional parameters to the 'clock-names' property in
order to provide an optional (E)MIO clock source.

Cirrus Logic CLPS711X GPIO controller
Required properties:
- compatible: Should be "cirrus,clps711x-gpio"
- reg: Physical base GPIO controller registers location and length.
There should be two registers, first is DATA register, the second

- gpio-controller: Marks the device node as a gpio controller.
- #gpio-cells: Should be two. The first cell is the pin number and
the second cell is used to specify the gpio polarity:

1 = active low
Note: Each GPIO port should have an alias correctly numbered in "aliases"
node.
Example:
aliases {
gpio0 = &porta;
};
porta: gpio@80000000 {

* Marvell EBU PCIe interfaces
Mandatory properties:
- compatible: one of the following values:
marvell,armada-370-pcie
marvell,armada-xp-pcie
marvell,kirkwood-pcie
- #address-cells, set to <3>

- bus-range: PCI bus numbers covered
- device_type, set to "pci"
- ranges: ranges for the PCI memory and I/O regions, as well as the
MMIO registers to control the PCIe interfaces.
In addition, the Device Tree node must have sub-nodes describing each
PCIe interface, having the following mandatory properties:
- reg: used only for interrupt mapping, so only the first four bytes
are used to refer to the correct bus number and device number.
- assigned-addresses: reference to the MMIO registers used to control
this PCIe interface.
- clocks: the clock associated to this PCIe interface
- marvell,pcie-port: the physical PCIe port number
- status: either "disabled" or "okay"
- device_type, set to "pci"
- #address-cells, set to <3>
- #size-cells, set to <2>
- #interrupt-cells, set to <1>
- ranges, empty property.
- interrupt-map-mask and interrupt-map, standard PCI properties to
define the mapping of the PCIe interface to interrupt numbers.
and the following optional properties:
- marvell,pcie-lane: the physical PCIe lane number, for ports having
multiple lanes. If this property is not found, we assume that the
value is 0.
