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.

MIPS CPU interrupt controller
On MIPS the mips_cpu_intc_init() helper can be used to initialize the 8 CPU
IRQs from a devicetree file and create a irq_domain for IRQ controller.
With the irq_domain in place we can describe how the 8 IRQs are wired to the
platforms internal interrupt controller cascade.
Below is an example of a platform describing the cascade inside the devicetree
and the code used to load it inside arch_init_irq().
Required properties:
- compatible : Should be "mti,cpu-interrupt-controller"
Example devicetree:
cpu-irq: cpu-irq@0 {
#address-cells = <0>;
interrupt-controller;
#interrupt-cells = <1>;
compatible = "mti,cpu-interrupt-controller";
};
intc: intc@200 {
compatible = "ralink,rt2880-intc";
reg = <0x200 0x100>;
interrupt-controller;
#interrupt-cells = <1>;
interrupt-parent = <&cpu-irq>;
interrupts = <2>;
};
Example platform irq.c:
static struct of_device_id __initdata of_irq_ids[] = {
{ .compatible = "mti,cpu-interrupt-controller", .data = mips_cpu_intc_init },
{ .compatible = "ralink,rt2880-intc", .data = intc_of_init },
{},
};
void __init arch_init_irq(void)
{
of_irq_init(of_irq_ids);
}

Lantiq SoC ASC serial controller
Required properties:
- compatible : Should be "lantiq,asc"
- reg : Address and length of the register set for the device
- interrupts: the 3 (tx rx err) interrupt numbers. The interrupt specifier
depends on the interrupt-parent interrupt controller.
Example:
asc1: serial@E100C00 {
compatible = "lantiq,asc";
reg = <0xE100C00 0x400>;
interrupt-parent = <&icu0>;
interrupts = <112 113 114>;
