Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus 

Pull MIPS updates from Ralf Baechle:
 "More hardware support across the field including a bunch of device
  drivers.  The highlight however really are further steps towards
  device tree.

  This has been sitting in -next for ages.  All MIPS _defconfigs have
  been tested to boot or where I don't have hardware available, to at
  least build fine."

* Compact Flash



The Cavium Compact Flash device is connected to the Octeon Boot Bus,

and is thus a child of the Boot Bus device.  It can read and write

industry standard compact flash devices.



Properties:

- compatible: "cavium,ebt3000-compact-flash";



  Compatibility with many Cavium evaluation boards.



- reg: The base address of the the CF chip select banks.  Depending on

  the device configuration, there may be one or two banks.



- cavium,bus-width: The width of the connection to the CF devices.  Valid

  values are 8 and 16.



- cavium,true-ide: Optional, if present the CF connection is in True IDE mode.



- cavium,dma-engine-handle: Optional, a phandle for the DMA Engine connected

  to this device.



Example:

	compact-flash@5,0 {

		compatible = "cavium,ebt3000-compact-flash";

		reg = <5 0 0x10000>, <6 0 0x10000>;

		cavium,bus-width = <16>;

* Boot Bus



The Octeon Boot Bus is a configurable parallel bus with 8 chip

selects.  Each chip select is independently configurable.



Properties:

- compatible: "cavium,octeon-3860-bootbus"



  Compatibility with all cn3XXX, cn5XXX and cn6XXX SOCs.



- reg: The base address of the Boot Bus' register bank.



- #address-cells: Must be <2>.  The first cell is the chip select

   within the bootbus.  The second cell is the offset from the chip select.



- #size-cells: Must be <1>.



- ranges: There must be one one triplet of (child-bus-address,

  parent-bus-address, length) for each active chip select.  If the

  length element for any triplet is zero, the chip select is disabled,

  making it inactive.



The configuration parameters for each chip select are stored in child

nodes.
