Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc

Browse Source 
Pull powerpc updates from Ben Herrenschmidt:
 "Here's the powerpc batch for this merge window.  Some of the
  highlights are:

   - A bunch of endian fixes ! We don't have full LE support yet in that
     release but this contains a lot of fixes all over arch/powerpc to
     use the proper accessors, call the firmware with the right endian
     mode, etc...

   - A few updates to our "powernv" platform (non-virtualized, the one
     to run KVM on), among other, support for bridging the P8 LPC bus
     for UARTs, support and some EEH fixes.

   - Some mpc51xx clock API cleanups in preparation for a clock API
     overhaul

   - A pile of cleanups of our old math emulation code, including better
     support for using it to emulate optional FP instructions on
     embedded chips that otherwise have a HW FPU.

   - Some infrastructure in selftest, for powerpc now, but could be
     generalized, initially used by some tests for our perf instruction
     counting code.

   - A pile of fixes for hotplug on pseries (that was seriously
     bitrotting)

   - The usual slew of freescale embedded updates, new boards, 64-bit
     hiberation support, e6500 core PMU support, etc..."

SEC 6 is as Freescale's Cryptographic Accelerator and Assurance Module (CAAM).
Currently Freescale powerpc chip C29X is embeded with SEC 6.
SEC 6 device tree binding include:
-SEC 6 Node
-Job Ring Node
-Full Example
=====================================================================
SEC 6 Node
Description
Node defines the base address of the SEC 6 block.
This block specifies the address range of all global
configuration registers for the SEC 6 block.
For example, In C293, we could see three SEC 6 node.
PROPERTIES
- compatible
Usage: required
Value type: <string>
Definition: Must include "fsl,sec-v6.0".
- fsl,sec-era
Usage: optional
Value type: <u32>
Definition: A standard property. Define the 'ERA' of the SEC
device.
- #address-cells
Usage: required
Value type: <u32>
Definition: A standard property. Defines the number of cells
for representing physical addresses in child nodes.
- #size-cells
Usage: required
Value type: <u32>
Definition: A standard property. Defines the number of cells
for representing the size of physical addresses in
child nodes.
- reg
Usage: required
Value type: <prop-encoded-array>
Definition: A standard property. Specifies the physical
address and length of the SEC 6 configuration registers.
- ranges
Usage: required
Value type: <prop-encoded-array>
Definition: A standard property. Specifies the physical address
range of the SEC 6.0 register space (-SNVS not included). A
triplet that includes the child address, parent address, &
length.
Note: All other standard properties (see the ePAPR) are allowed
but are optional.
EXAMPLE
crypto@a0000 {
compatible = "fsl,sec-v6.0";
fsl,sec-era = <6>;
#address-cells = <1>;
#size-cells = <1>;
reg = <0xa0000 0x20000>;
ranges = <0 0xa0000 0x20000>;
};
=====================================================================
Job Ring (JR) Node
Child of the crypto node defines data processing interface to SEC 6
across the peripheral bus for purposes of processing
cryptographic descriptors. The specified address
range can be made visible to one (or more) cores.
The interrupt defined for this node is controlled within
the address range of this node.
- compatible
Usage: required
Value type: <string>
Definition: Must include "fsl,sec-v6.0-job-ring".
- reg
Usage: required
Value type: <prop-encoded-array>
Definition: Specifies a two JR parameters: an offset from
the parent physical address and the length the JR registers.
- interrupts
Usage: required
Value type: <prop_encoded-array>
Definition: Specifies the interrupts generated by this
device. The value of the interrupts property
consists of one interrupt specifier. The format
of the specifier is defined by the binding document
describing the node's interrupt parent.
EXAMPLE
jr@1000 {
compatible = "fsl,sec-v6.0-job-ring";
reg = <0x1000 0x1000>;
interrupts = <49 2 0 0>;
};
===================================================================
Full Example
Since some chips may contain more than one SEC, the dtsi contains
only the node contents, not the node itself. A chip using the SEC
should include the dtsi inside each SEC node. Example:
In qoriq-sec6.0.dtsi:
compatible = "fsl,sec-v6.0";
fsl,sec-era = <6>;
#address-cells = <1>;
#size-cells = <1>;
jr@1000 {
compatible = "fsl,sec-v6.0-job-ring",
"fsl,sec-v5.2-job-ring",
"fsl,sec-v5.0-job-ring",
"fsl,sec-v4.4-job-ring",
"fsl,sec-v4.0-job-ring";
reg = <0x1000 0x1000>;
};
jr@2000 {
compatible = "fsl,sec-v6.0-job-ring",
"fsl,sec-v5.2-job-ring",
"fsl,sec-v5.0-job-ring",
"fsl,sec-v4.4-job-ring",
"fsl,sec-v4.0-job-ring";
reg = <0x2000 0x1000>;
};
In the C293 device tree, we add the include of public property:
crypto@a0000 {
/include/ "qoriq-sec6.0.dtsi"
}
crypto@a0000 {
reg = <0xa0000 0x20000>;
ranges = <0 0xa0000 0x20000>;
jr@1000 {
interrupts = <49 2 0 0>;
};
jr@2000 {
interrupts = <50 2 0 0>;
};
};

* Freescale MSI interrupt controller
Required properties:
- compatible : compatible list, contains 2 entries,
first is "fsl,CHIP-msi", where CHIP is the processor(mpc8610, mpc8572,
etc.) and the second is "fsl,mpic-msi" or "fsl,ipic-msi" depending on
the parent type.
- compatible : compatible list, may contain one or two entries
The first is "fsl,CHIP-msi", where CHIP is the processor(mpc8610, mpc8572,
etc.) and the second is "fsl,mpic-msi" or "fsl,ipic-msi" or
"fsl,mpic-msi-v4.3" depending on the parent type and version. If mpic
version is 4.3, the number of MSI registers is increased to 16, MSIIR1 is
provided to access these 16 registers, and compatible "fsl,mpic-msi-v4.3"
should be used. The first entry is optional; the second entry is
required.
- reg : It may contain one or two regions. The first region should contain
the address and the length of the shared message interrupt register set.
The second region should contain the address of aliased MSIIR register for
platforms that have such an alias.
- msi-available-ranges: use <start count> style section to define which
msi interrupt can be used in the 256 msi interrupts. This property is
optional, without this, all the 256 MSI interrupts can be used.
Each available range must begin and end on a multiple of 32 (i.e.
no splitting an individual MSI register or the associated PIC interrupt).
The second region should contain the address of aliased MSIIR or MSIIR1
register for platforms that have such an alias, if using MSIIR1, the second
region must be added because different MSI group has different MSIIR1 offset.
- interrupts : each one of the interrupts here is one entry per 32 MSIs,
and routed to the host interrupt controller. the interrupts should
