This patch adds clock modules for MediaTek SoCs: - Shared part: a common driver which contains the general operations for plls, muxes, dividers and gates so that we can reuse it in future.

- Specific SoC part: the group of structures used to hold the hardware configuration for each SoC.

We take MT7629 as an example to demonstrate how to implement driver if any other MediaTek chips would like to use it.

This patch adds pinctrl support for MT7629 SoC. The IO core found on the SoC has the registers for pinctrl, pinconf and gpio mixed up in the same register range. Hence the driver also implements the gpio functionality through UCLASS_GPIO.

This also creates a common file as there might be other chips that use the same binding and driver, then being a little more abstract could help in the long run.

This adds a power domain driver for the Mediatek SCPSYS unit.

The System Control Processor System (SCPSYS) has several power management related tasks in the system. The tasks include thermal measurement, dynamic voltage frequency scaling (DVFS), interrupt filter and lowlevel sleep control. The System Power Manager (SPM) inside the SCPSYS is for the MTCMOS power domain control.

For now this driver only adds power domain support.

This patch adds an extra operation in ns16550.c to suuport MediaTek SoCs as we have a highspeed register which influences the calcualtion of the divisor.

Note that we don't support the baudrate greater than 115200 currently.
