Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
o Add basic support for the Mediatek/Ralink Wireless SoC family.
o The Qualcomm Atheros platform is extended by support for the new
QCA955X SoC series as well as a bunch of patches that get the code
ready for OF support.
o Lantiq and BCM47XX platform have a few improvements and bug fixes.
o MIPS has sent a few patches that get the kernel ready for the
upcoming microMIPS support.
o The rest of the series is made up of small bug fixes and cleanups
that relate to various parts of the MIPS code. The biggy in there is
a whitespace cleanup. After I was sent another set of whitespace
cleanup patches I decided it was the time to clean the whitespace
"issues" for once and and that touches many files below arch/mips/.
Fix up silly conflicts, mostly due to whitespace cleanups.

1 | MIPS CPU interrupt controller | ||
2 | |||
3 | On MIPS the mips_cpu_intc_init() helper can be used to initialize the 8 CPU | ||
4 | IRQs from a devicetree file and create a irq_domain for IRQ controller. | ||
5 | |||
6 | With the irq_domain in place we can describe how the 8 IRQs are wired to the | ||
7 | platforms internal interrupt controller cascade. | ||
8 | |||
9 | Below is an example of a platform describing the cascade inside the devicetree | ||
10 | and the code used to load it inside arch_init_irq(). | ||
11 | |||
12 | Required properties: | ||
13 | - compatible : Should be "mti,cpu-interrupt-controller" | ||

15 | Example devicetree: | ||
16 | cpu-irq: cpu-irq@0 { | ||
17 | #address-cells = <0>; | ||
18 | |||
19 | interrupt-controller; | ||
20 | #interrupt-cells = <1>; | ||
