Implements OF support and add code to load custom properties from the DT. The Serial To Parallel (STP) is found on MIPS based Lantiq socs. It is a peripheral controller used to drive external shift register cascades. At most 3 groups of 8 bits can be driven. The hardware is able to allow the DSL modem to drive the 2 LSBs of the cascade automatically. Newer socs are also able to automatically drive some pins via the internal PHYs. The driver currently only supports output functionality. Patches for the input feature found on newer generations of the soc will be provided in a later series.

Implements OF support and convert to of_mm_gpio. By attaching hardware latches to the External Bus Unit (EBU) on Lantiq SoC, it is possible to create output only gpios. This driver configures a special memory address, which when written to, outputs 16 bit to the latches.

This patch unifies all clock generation and gating code into one file. All drivers will now be able to request their clocks via their device.

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.

Add support for irq_domain on lantiq socs. The conversion is straight forward as the ICU found inside the socs allows the usage of irq_domain_add_linear. Harware IRQ 0->7 are the generic MIPS IRQs. 8->199 are the Lantiq IRQ Modules. Our irq_chip callbacks need to substract 8 (MIPS_CPU_IRQ_CASCADE) from d->hwirq to find out the correct offset into the Interrupt Modules register range.

Commit 069d4e74 ("ARM: EXYNOS4: Remove clock event timers using ARM private timers") removed support for local timers and forced to use MCT as event source. However MCT is not operating properly on early revision of EXYNOS4 SoCs. All UniversalC210 boards are based on it, so that commit broke support for it. This patch provides a workaround that enables UniversalC210 boards to boot again. s5p-timer is used as an event source, it works only for non-SMP builds.
