The MAX8907 is an I2C-based power-management IC containing voltage regulators, a reset controller, a real-time clock, and a touch-screen controller. The original driver was written by: * Gyungoh Yoo <jack.yoo@maxim-ic.com> Various fixes and enhancements by: * Jin Park <jinyoungp@nvidia.com> * Tom Cherry <tcherry@nvidia.com> * Prashant Gaikwad <pgaikwad@nvidia.com> * Dan Willemsen <dwillemsen@nvidia.com> * Laxman Dewangan <ldewangan@nvidia.com> During upstreaming, I (swarren): * Converted to regmap. * Allowed probing from device tree. * Reworked the regulator driver to be represented as a single device that provides multiple regulators, rather than as a device per regulator. * Replaced many regulator ops with standard functions. * Added ability to specify supplies for each regulator. * Removed the WLED regulator. If/when we expose this in the driver, it should be a backlight object not a regulator object. * Renamed from max8907c->max8907, since the driver covers at least the C and B revisions. * General cleanup.

The helper routine is meant to be used by the regulator drivers to extract the regulator_init_data structure from the data that is passed from device tree. '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. They will be revisited later. Signed-off-by: NRajendra Nayak <rnayak@ti.com> Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com>

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.

由 MyungJoo Ham 提交于
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 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.
