regulator: Add Renesas PMIC RAA215300 driver The RAA215300 is a 9-channel PMIC that consists of * Internally compensated regulators * built-in Real Time Clock (RTC) * 32kHz crystal oscillator * coin cell battery charger The RTC on RAA215300 is similar to the IP found in the ISL1208. The existing driver for the ISL1208 works for this PMIC too, however the RAA215300 exposes two devices via I2C, one for the RTC IP, and one for everything else. The RTC IP has to be enabled by the other I2C device, therefore this driver is necessary to get the RTC to work. The external oscillator bit is inverted on PMIC version 0x11. Add PMIC RAA215300 driver for enabling RTC block and instantiating RTC device based on PMIC version.

regulator: Introduce tps68470-regulator driver The TPS68470 PMIC provides Clocks, GPIOs and Regulators. At present in the kernel the Regulators and Clocks are controlled by an OpRegion driver designed to work with power control methods defined in ACPI, but some platforms lack those methods, meaning drivers need to be able to consume the resources of these chips through the usual frameworks. This commit adds a driver for the regulators provided by the tps68470, and is designed to bind to the platform_device registered by the intel_skl_int3472 module. This is based on this out of tree driver written by Intel: https://github.com/intel/linux-intel-lts/blob/4.14/base/drivers/regulator/tps68470-regulator.c with various cleanups added.

regulator: bd70528: Drop BD70528 support The only known BD70528 use-cases are such that the PMIC is controlled from separate MCU which is not running Linux. I am not aware of any Linux driver users. Furthermore, it seems there is no demand for this IC. Let's ease the maintenance burden and drop the driver. We can always add it back if there is sudden need for it.

regulator: Support ROHM BD71815 regulators Support voltage control for regulators on ROHM BD71815 PMIC. ROHM BD71815 contains 5 bucks, 7 LDOs and a boost (intended for LED). Bucks 1 and 2 support HW state based voltage level and enable states. Other regulators support HW state based enable states. All bucks and LDOs 1-5 allow voltage changes for RUN state and LDO4 can be enabled/disabled via GPIO. LDO3 does support changing between two predetermined voltages by using a GPIO but this functionality is not included in this commit. This work is derived from driver originally written by Tony Luo <luofc@embedinfo.com> - although not much of original work is left.

regulator: add QCOM RPMh regulator driver Add the QCOM RPMh regulator driver to manage PMIC regulators which are controlled via RPMh on some Qualcomm Technologies, Inc. SoCs. RPMh is a hardware block which contains several accelerators which are used to manage various hardware resources that are shared between the processors of the SoC. The final hardware state of a regulator is determined within RPMh by performing max aggregation of the requests made by all of the processors. Add support for PMIC regulator control via the voltage regulator manager (VRM) and oscillator buffer (XOB) RPMh accelerators. VRM supports manipulation of enable state, voltage, and mode. XOB supports manipulation of enable state.

License cleanup: add SPDX GPL-2.0 license identifier to files with no license Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

But the same object file name (max77686.o) was used for both the common MFD driver and the max77686 regulator one. This confuses kbuild if both drivers are built as module causing the MFD driver to not be copied when installing the modules.

regulator: Introduce TI Adaptive Body Bias(ABB) on-chip LDO driver Adaptive Body Biasing (ABB) modulates transistor bias voltages dynamically in order to optimize switching speed versus leakage. Texas Instruments' SmartReflex 2 technology provides support for this power management technique with Forward Body Biasing (FBB) and Reverse Body Biasing (RBB). These modulate the body voltage of transistor cells or blocks dynamically to gain performance and reduce leakage. TI's SmartReflex white paper[1] has further information for usage in conjunction with other power management techniques. The application of FBB/RBB technique is determined for each unique device in some process nodes, whereas, they are mandated on other process nodes. In a nutshell, ABB technique is implemented on TI SoC as an on-chip LDO which has ABB module controlling the bias voltage. However, the voltage is unique per device. These vary per SoC family and the manner in which these techniques are used may vary depending on the Operating Performance Point (OPP) voltage targeted. For example: OMAP3630/OMAP4430: certain OPPs mandate usage of FBB independent of devices. OMAP4460/OMAP4470: certain OPPs mandate usage of FBB, while others may optionally use FBB or optimization with RBB. OMAP5: ALL OPPs may optionally use ABB, and ABB biasing voltage is influenced by vset fused in s/w and requiring s/w override of default values. Further, two generations of ABB module are used in various TI SoCs. They have remained mostly register field compatible, however the register offset had switched between versions. We introduce ABB LDO support in the form of a regulator which is controlled by voltages denoting the desired Operating Performance Point which is targeted. However, since ABB transition is part of OPP change sequence, the sequencing required to ensure sane operation w.r.t OPP change is left to the controlling driver (example: cpufreq SoC driver) using standard regulator operations. The driver supports all ABB modes and ability to override ABB LDO vset control efuse based ABB mode detection etc. Current implementation is heavily influenced by the original patch series [2][3] from Mike Turquette. However, the current implementation supports only device tree based information.

'consumer_supplies' which is part of regulator_init_data is not extracted as the regulator consumer mappings are passed through DT differently, implemented in subsequent patches. Similarly the regulator<-->parent/supply mapping is handled in subsequent patches. Also add documentation for regulator bindings to be used to pass regulator_init_data struct information from device tree. Some of the regulator properties which are linux and board specific, are left out since its not clear if they can be in someway embedded into the kernel or passed in from DT.

regulator: Add driver for gpio-controlled regulators This patch adds support for regulators that can be controlled via gpios. Examples for such regulators are the TI-tps65024x voltage regulators with 4 fixed and 1 runtime-switchable voltage regulators or the TI-bq240XX charger regulators. The number of controlling gpios is not limited, the mapping between voltage/current and target gpio state is done via the states map and the driver can be used for either voltage or current regulators. A mapping for a regulator with two GPIOs could look like: gpios = { { .gpio = GPIO1, .flags = GPIOF_OUT_INIT_HIGH, .label = "gpio name 1" }, { .gpio = GPIO2, .flags = GPIOF_OUT_INIT_LOW, .label = "gpio name 2" }, } The flags element of the gpios array determines the initial state of the gpio, set during probe. The initial state of the regulator is also calculated from these values states = { { .value = volt_or_cur1, .gpios = (0 << 1) | (0 << 0) }, { .value = volt_or_cur2, .gpios = (0 << 1) | (1 << 0) }, { .value = volt_or_cur3, .gpios = (1 << 1) | (0 << 0) }, { .value = volt_or_cur4, .gpios = (1 << 1) | (1 << 0) }, } The target-state for the n-th gpio is determined by the n-th bit in the bitfield of the target-value.

regulator: MAX8997/8966 support This patch supports PMIC/Regulator part of MAX8997/MAX8966 MFD. In this initial release, selecting voltages or current-limit and switching on/off the regulators are supported. Controlling voltages for DVS with GPIOs is not implemented fully and requires more considerations: it controls multiple bucks (selection of 1, 2, and 5) at the same time with SET1~3 gpios. Thus, when DVS-GPIO is activated, we lose the ability to control the voltage of a single buck regulator independently; i.e., contolling a buck affects other two bucks. Therefore, using the conventional regulator framework directly might be problematic. However, in this driver, we try to choose a setting without such side effect of affecting other regulators and then try to choose a setting with the minimum side effect (the sum of voltage changes in other regulators). On the other hand, controlling all the three bucks simultenously based on the voltage set table may help build cpufreq and similar system more robust; i.e., all the three voltages are consistent every time without glitches during transition.

MAX8952 PMIC Driver Initial Release MAX8952 PMIC is used to provide voltage output between 770mV - 1400mV with DVS support. In this initial release, users can set voltages for four DVS modes, RAMP delay values, and SYNC frequency. Controlling FPWM/SYNC_MODE/Pull-Down/Ramp Modes and reading CHIP_ID is not supported in this release. If GPIO of EN is not valid in platform data, the driver assumes that it is always-on. If GPIO of VID0 or VID1 is invalid, the driver pulls down VID0 and VID1 to fix DVS mode as 0 and disables DVS support. We assume that V_OUT is capable to provide every voltage from 770mV to 1.40V in 10mV steps although the data sheet has some ambiguity on it.

regulator: Provide optional dummy regulator for consumers In order to ease transitions with drivers are boards start using regulators provide an option to cause all regulator_get() calls to succeed, with a dummy always on regulator being supplied where one has not been configured. A warning is printed whenever the dummy regulator is used to aid system development. This regulator does not implement any regulator operations but will allow simple consumers which only do enable() and disable() calls to run. It is kept separate from the fixed voltage regulator to avoid Kconfig confusion on the part of users when it is extended to allow boards to explicitly use the dummy regulator to simplify cases where the majority of supplies are from fixed regulators without software control. This option is currently only effective for systems which do not specify full constriants. If required an override could also be provided to allow these systems to use the dummy regulator, though it is likely that unconfigured supplies on such systems will lead to error due to regulators being powered down more aggressively when not in use.

regulator: twl4030 regulators Support most of the LDO regulators in the twl4030 family chips. In the case of LDOs supporting MMC/SD, the voltage controls are used; but in most other cases, the regulator framework is only used to enable/disable a supplies, conserving power when a given voltage rail is not needed. The drivers/mfd/twl4030-core.c code already sets up the various regulators according to board-specific configuration, and knows that some chips don't provide the full set of voltage rails. The omitted regulators are intended to be under hardware control, such as during the hardware-mediated system powerup, powerdown, and suspend states. Unless/until software hooks are known to be safe, they won't be exported here. These regulators implement the new get_status() operation, but can't realistically implement get_mode(); the status output is effectively the result of a vote, with the relevant hardware inputs not exposed.
