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."

+* 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.
+
+Configuration Properties:
+- compatible:  "cavium,octeon-3860-bootbus-config"
+
+- cavium,cs-index: A single cell indicating the chip select that
+  corresponds to this configuration.
+
+- cavium,t-adr: A cell specifying the ADR timing (in nS).
+
+- cavium,t-ce: A cell specifying the CE timing (in nS).
+
+- cavium,t-oe: A cell specifying the OE timing (in nS).
+
+- cavium,t-we: A cell specifying the WE timing (in nS).
+
+- cavium,t-rd-hld: A cell specifying the RD_HLD timing (in nS).
+
+- cavium,t-wr-hld: A cell specifying the WR_HLD timing (in nS).
+
+- cavium,t-pause: A cell specifying the PAUSE timing (in nS).
+
+- cavium,t-wait: A cell specifying the WAIT timing (in nS).
+
+- cavium,t-page: A cell specifying the PAGE timing (in nS).
+
+- cavium,t-rd-dly: A cell specifying the RD_DLY timing (in nS).
+
+- cavium,pages: A cell specifying the PAGES parameter (0 = 8 bytes, 1
+  = 2 bytes, 2 = 4 bytes, 3 = 8 bytes).
+
+- cavium,wait-mode: Optional.  If present, wait mode (WAITM) is selected.
+
+- cavium,page-mode: Optional.  If present, page mode (PAGEM) is selected.
+
+- cavium,bus-width: A cell specifying the WIDTH parameter (in bits) of
+  the bus for this chip select.
+
+- cavium,ale-mode: Optional.  If present, ALE mode is selected.
+
+- cavium,sam-mode: Optional.  If present, SAM mode is selected.
+
+- cavium,or-mode: Optional.  If present, OR mode is selected.
