2012-06-03regulator: Add support for RICOH PMIC RC5T583 regulatorLaxman Dewangan
The RC5T583 PMIC from RICOH consists of 4 DCDC and 10 LDOs. This driver supports the control of different regulator output through regulator interface. This driver depends on MFD driver of RC5T583 and uses mfd rc5t583 apis to communicate to device for accessing different device's registers.

2012-04-05Regulator: gpio_swtich: Remove gpio_switch regulator driverLaxman Dewangan
The gpio_switch regulator is NV driver developed during tegra3 bringup time. The driver functionality is upstreamed to mainline into fixed regulator and it is accepted by community. The required functionality is also downstream and required client driver is moved to use the fixed regulator. Hence this driver is just duplicating functionality with fixed regulator and hence removing this.

2012-01-19regulator: Add driver for gpio-controlled regulatorsHeiko Stübner
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.

2011-03-23regulator: MAX8997/8966 supportMyungJoo Ham
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.

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.

2010-03-03regulator: Provide optional dummy regulator for consumersMark Brown
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.

2009-12-17regulator/mc13783: rename source file to match other driversUwe Kleine-König
One annoying thing about the old name was that the module was just called mc13783 which caused wrong expectations (at least for me).

2009-12-17regulator: add 88PM8607 PMIC driverHaojian Zhuang
Hi Liam, Since Samuel merged a new version of mfd 88pm8607 driver, I format a new patch on regulator 88pm8607. I paste the new patch in mail. Please help to review again. And I also attach the mfd driver in mail. From: Haojian Zhuang <haojian.zhuang@marvell.com> Date: Thu, 8 Oct 2009 09:36:53 -0400 Subject: [PATCH] regulator: Add 88PM8607 PMIC driver This patch adds regulator drivers for Marvell 88PM8607 PMIC. This controller contains 3 DVC and 14 LDO regulators. This controller uses I2C interface. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>

2009-12-13mfd: Rename twl4030* driver files to enable re-useSantosh Shilimkar
The upcoming TWL6030 is companion chip for OMAP4 like the current TWL4030 for OMAP3. The common modules like RTC, Regulator creates opportunity to re-use the most of the code from twl4030. This patch renames few common drivers twl4030* files to twl* to enable the code re-use.

2009-09-17regulator: AB3100 supportLinus Walleij
This adds support for the regulators found in the AB3100 Mixed-Signal IC. It further also defines platform data for the ST-Ericsson U300 platform and extends the AB3100 MFD driver so that platform/board data with regulation constraints and an init function can be passed down all the way from the board to the regulators.

2009-09-17regulator: Add WM831x LDO supportMark Brown
The WM831x series of devices provide three types of LDO: - General purpose LDOs supporting voltages from 0.9-3.3V - High performance analogue LDOs supporting voltages from 1-3.5V - Very low power consumption LDOs intended to support always on functionality. This patch adds support for all three kinds of LDO. Each regulator is probed as an individual platform device with resources used to provide the register map location of the regulator. Mixed hardware and software control of regulators is not current supported.

2009-09-17regulator: Add WM831x DC-DC buck convertor supportMark Brown
The WM831x series of devices all have 3 DC-DC buck convertors. This driver implements software control for these regulators via the regulator API. Use with split hardware/software control of individual regulators is not supported, though regulators not controlled by software may be controlled via the hardware control interfaces.
