3f8565be1e MIPS: lantiq: xway: add prototype for ltq_get_cp1_base()
ltq_get_cp1_base() is an exported function, we must define
its prototype on header file. Fix warning:

863be3c3ab MIPS: Add header files reference with path prefix
There are some common header files which are referenced locally
with #includenext method, includenext is tricky method and only
used on mips platform.

This patech removes includenext method, replace it with defailed
pathname prefix for header files.

This patch passes to compile on all mips platform with defconfig,
and is verified on my loongson64 box.

Changes:
--------
v2:
  - Fix compiling issue on malta platform

MIPS: lantiq: Use CP0_LEGACY_COMPARE_IRQ
Instead of using the lantiq specific MIPS_CPU_TIMER_IRQ use the generic
CP0_LEGACY_COMPARE_IRQ constant for the timer interrupt number.

bd51db7f3b MIPS: lantiq: drop ltq_gpio_request() and gpio_to_irq()
As part of the conversion to OF we also implement pinctrl drivers. Previously
we used ltq_gpio_request() to set pinmuxing. This is now obselete and we can
hence drop the function.

Additionally we remove gpio_to_irq() from the gpio driver and move it to a
header file.

8ec6d93508 MIPS: Lantiq: add SoC specific code for XWAY family
Add support for the Lantiq XWAY family of Mips24KEc SoCs.

* Danube (PSB50702)
* Twinpass (PSB4000)
* AR9 (PSB50802)
* Amazon SE (PSB5061)

The Amazon SE is a lightweight SoC and has no PCI as well as a different
clock. We split the code out into seperate files to handle this.

The GPIO pins on the SoCs are multi function and there are several bits
we can use to configure the pins. To be as compatible as possible to
GPIOLIB we add a function

int lq_gpio_request(unsigned int pin, unsigned int alt0,
        unsigned int alt1, unsigned int dir, const char *name);

which lets you configure the 2 "alternate function" bits. This way drivers like
PCI can make use of GPIOLIB without a cubersome wrapper.

The PLL code inside arch/mips/lantiq/xway/clk-xway.c is voodoo to me. It was
taken from a 2.4.20 source tree and was never really changed by me since then.
