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.

Many SoCs from MediaTek have a high-speed uart. This UART is compatible with the ns16550 in legacy mode. It has extra registers for high-speed mode which can reach a maximum baudrate at 921600.

However this UART will no longer be compatible if it's in high-speed mode. Some BootROM of MediaTek's SoCs will change the UART into high-speed mode and the U-Boot must use this driver to initialize the UART.
