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

…ream-linus

Pull MIPS update from Ralf Baechle:
 "This is the MIPS update for 3.7.

  A fair chunk of them are platform updates to the Cavium Octeon SOC
  (which involves machine generated header files of considerable size),
  Atheros ATH79xx, RMI aka Netlogic aka Broadcom XLP, Broadcom BCM63xx
  platforms.

  Support for the commercial MIPS simulator MIPSsim has been removed as
  MIPS Technologies is shifting away from this product and Qemu is
  offering various more powerful platforms.  The generic MIPS code can
  now also probe for no-execute / write-only TLB features implemented
  without the full SmartMIPS extension as permitted by the latest MIPS
  processor architecture.  Lots of small changes to generic code."

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (78 commits)
  MIPS: ath79: Fix CPU/DDR frequency calculation for SRIF PLLs
  MIPS: ath79: use correct fractional dividers for {CPU,DDR}_PLL on AR934x
  MIPS: BCM63XX: Properly handle mac address octet overflow
  MIPS: Kconfig: Avoid build errors by hiding USE_OF from the user.
  MIPS: Replace `-' in defconfig filename wth `_' for consistency.
  MIPS: Wire kcmp syscall.
  MIPS: MIPSsim: Remove the MIPSsim platform.
  MIPS: NOTIFY_RESUME is not needed in TIF masks
  MIPS: Merge the identical "return from syscall" per-ABI code
  MIPS: Unobfuscate _TIF..._MASK
  MIPS: Prevent hitting do_notify_resume() with !user_mode(regs).
  MIPS: Replace 'kernel_uses_smartmips_rixi' with 'cpu_has_rixi'.
  MIPS: Add base architecture support for RI and XI.
  MIPS: Optimise TLB handlers for MIPS32/64 R2 cores.
  MIPS: uasm: Add INS and EXT instructions.
  MIPS: Avoid pipeline stalls on some MIPS32R2 cores.
  MIPS: Make VPE count to be one-based.
  MIPS: Add new end of interrupt functionality for GIC.
  MIPS: Add EIC support for GIC.
  MIPS: Code clean-ups for the GIC.

+Lantiq FALCON pinmux controller

+
+Please refer to pinctrl-bindings.txt in this directory for details of the

+phrase "pin configuration node".
+
+Lantiq's pin configuration nodes act as a container for an abitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those group(s), and two pin configuration parameters:
+pull-up and open-drain
+
+The name of each subnode is not important as long as it is unique; all subnodes
+should be enumerated and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+We support 2 types of nodes.
