soc: mediatek: Add PMIC wrapper for MT8135 and MT8173 SoCs This adds support for the PMIC wrapper found on MediaTek MT8135 and MT8173 SoCs. The PMIC wrapper is found on MT6xxx SoCs aswell but these are currently not supported. On MediaTek MT8135, MT8173 and other SoCs the PMIC is connected via SPI. The SPI master interface is not directly visible to the CPU, but only through the PMIC wrapper inside the SoC. The communication between the SoC and the PMIC can optionally be encrypted. Also a non standard Dual IO SPI mode can be used to increase speed. The MT8135 also supports a special feature named "IP Pairing". With IP Pairing the pins of some SoC internal peripherals can be on the PMIC. The signals of these pins are routed over the SPI bus using the pwrap bridge. Because of these optional non SPI conform features the PMIC driver is not implemented as a SPI bus master driver.

soc: mediatek: Add infracfg misc driver support This adds support for some miscellaneous bits of the infracfg controller. The mtk_infracfg_set/clear_bus_protection functions are necessary for the scpsys power domain driver to handle the bus protection bits which are contained in the infacfg register space.

Say yes here to add support for the MediaTek INFRACFG controller. The
INFRACFG controller contains various infrastructure registers not
directly associated to any device.

Say yes here to add support for MediaTek PMIC Wrapper found
on different MediaTek SoCs. The PMIC wrapper is a proprietary
hardware to connect the PMIC.
soc: Mediatek: Add SCPSYS power domain driver 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, the more advanced features are not yet supported. The driver implements the generic PM domain device tree bindings, the first user will most likely be the Mediatek AFE audio driver.
