Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-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
+
+Required properties:
+- compatible: "lantiq,pinctrl-falcon"
+- reg: Should contain the physical address and length of the gpio/pinmux
+ register range
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning 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.
+
+Definition of mux function groups:
+
+Required subnode-properties:
+- lantiq,groups : An array of strings. Each string contains the name of a group.
+ Valid values for these names are listed below.
+- lantiq,function: A string containing the name of the function to mux to the
+ group. Valid values for function names are listed below.
+
+Valid values for group and function names:
+
+ mux groups:
+ por, ntr, ntr8k, hrst, mdio, bootled, asc0, spi, spi cs0, spi cs1, i2c,
+ jtag, slic, pcm, asc1
+
+ functions:
+ rst, ntr, mdio, led, asc, spi, i2c, jtag, slic, pcm
+
+
+Definition of pin configurations:
+
+Required subnode-properties:
+- lantiq,pins : An array of strings. Each string contains the name of a pin.
+ Valid values for these names are listed below.
+
+Optional subnode-properties:
+- lantiq,pull: Integer, representing the pull-down/up to apply to the pin.
+ 0: none, 1: down
+- lantiq,drive-current: Boolean, enables drive-current
+- lantiq,slew-rate: Boolean, enables slew-rate
+
+Example:
+ pinmux0 {
+ compatible = "lantiq,pinctrl-falcon";
+ pinctrl-names = "default";
+ pinctrl-0 = <&state_default>;
+
+ state_default: pinmux {
+ asc0 {
