soc: samsung: Add exynos chipid driver support Exynos SoCs have Chipid, for identification of product IDs and SoC revisions. This patch intends to provide initialization code for all these functionalities, at the same time it provides some sysfs entries for accessing these information to user-space. This driver uses existing binding for exynos-chipid. Changes by Bartlomiej: - fixed return values on errors - removed bogus kfree_const() - added missing Exynos4210 EVT0 id - converted code to use EXYNOS_MASK define - fixed np use after of_node_put() - fixed too early use of dev_info() - made driver fail for unknown SoC-s - added SPDX tag - updated Copyrights Signed-off-by: Pankaj Dubey <pankaj.dubey@samsung.com> [m.szyprowski: for suggestion and code snippet of product_id_to_soc_id] Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> [s.nawrocki: updated copyright date, removed uneeded headers inclusion] Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

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].

soc: samsung: exynos-chipid: convert to driver and merge exynos-asv The Exynos Chip ID driver on Exynos SoCs has so far only informational purpose - to expose the SoC device in sysfs. No other drivers depend on it so there is really no benefit of initializing it early. The code would be the most flexible if converted to a regular driver. However there is already another driver - Exynos ASV (Adaptive Supply Voltage) - which binds to the device node of Chip ID. The solution is to convert the Exynos Chip ID to a built in driver and merge the Exynos ASV into it. This has several benefits: 1. Although the Exynos ASV driver binds to a device node present in all Exynos DTS (generic compatible), it fails to probe except on the supported ones (only Exynos5422). This means that the regular boot process has a planned/normal device probe failure. Merging the ASV into Chip ID will remove this probe failure because the final driver will always bind, just with disabled ASV features. 2. Allows to use dev_info() as the SoC bus is present (since core_initcall). 3. Could speed things up because of execution of Chip ID code in a SMP environment (after bringing up secondary CPUs, unlike early_initcall), This reduces the amount of work to be done early, when the kernel has to bring up critical devices. 5. Makes the Chip ID code defer-probe friendly, Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Link: https://lore.kernel.org/r/20201207190517.262051-5-krzk@kernel.org Reviewed-by: Pankaj Dubey <pankaj.dubey@samsung.com>

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.

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: 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.
