drivers: soc: Add support for Exynos PMU driver This patch moves Exynos PMU driver implementation from "arm/mach-exynos" to "drivers/soc/samsung". This driver is mainly used for setting misc bits of register from PMU IP of Exynos SoC which will be required to configure before Suspend/Resume. Currently all these settings are done in "arch/arm/mach-exynos/pmu.c" but moving ahead for ARM64 based SoC support, there is a need of this PMU driver in driver/* folder. This driver uses existing DT binding information and there should be no functionality change in the supported platforms.

soc: samsung: Rename Samsung and Exynos to lowercase Fix up inconsistent usage of upper and lowercase letters in "Samsung" and "Exynos" names. "SAMSUNG" and "EXYNOS" are not abbreviations but regular trademarked names. Therefore they should be written with lowercase letters starting with capital letter. The lowercase "Exynos" name is promoted by its manufacturer Samsung Electronics Co., Ltd., in advertisement materials and on website. Although advertisement materials usually use uppercase "SAMSUNG", the lowercase version is used in all legal aspects (e.g. on Wikipedia and in privacy/legal statements on https://www.samsung.com/semiconductor/privacy-global/).

soc: samsung: Add Exynos Adaptive Supply Voltage driver The Adaptive Supply Voltage (ASV) driver adjusts CPU cluster operating points depending on exact revision of an SoC retrieved from the CHIPID block or the OTP memory. This allows for some power saving as for some CPU clock frequencies we can lower CPU cluster's supply voltage comparing to safe values common to all the SoC revisions. This patch adds support for Exynos5422/5800 SoC, it is partially based on code from https://github.com/hardkernel/linux repository, branch odroidxu4-4.14.y, files: arch/arm/mach-exynos/exynos5422-asv.[ch].

bool "Exynos PMU controller driver" if COMPILE_TEST
soc: samsung: Do not build ARMv7 PMU drivers on ARMv8 The Exynos Power Management Unit (PMU) drivers contain quite large static arrays of register values necessary for given Exynos SoC to enter low power mode. All this data is useless for ARMv8 SoC like Exynos5433, because the image will not be shared between ARMv7 and ARMv8. Add additional Kconfig symbol for selecting the SoC-specific driver addons thus skipping the useless data in the final image (this is similar approach to chosen for Exynos clock controller drivers): - exynos-pmu driver will be compiled on both architectures ARMv7 and ARMv8, - additional driver_data for ARMv7 SoCs will not be built on ARMv8 and a macro will return NULL for them in of_device_id - this should be safe as these compatibles cannot match on ARMv7 and driver anyway handles NULL driver_data, - on ARMv8 compile only exynos-pmu driver which exposes the syscon-regmap for PMU address space.

soc: samsung: exynos-regulator-coupler: Add simple voltage coupler for Exynos5800 Add a simple custom voltage regulator coupler for Exynos5800 SoCs, which require coupling between "vdd_arm" and "vdd_int" regulators. This coupler ensures that the voltage values don't go below the bootloader-selected operation point during the boot process until the clients set their constraints. It is achieved by assuming minimal voltage value equal to the current value if no constraints are set. This also ensures proper voltage balancing if any of the client driver is missing. The balancing code comes from the regulator/core.c with the additional logic for handling regulators without client constraints applied added.
