regulator: Add driver for gpio-controlled regulators

2011-10-09T11:36:21Z

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.

mach-ux500: voltage domain regulators for DB8500

2011-05-24T20:20:23Z

The DB8500 has ePOD:s (electronic power domains) which are possible to switch on/off to deactivate silicon blocks on the DB8500 SoC by cutting their power without retention. We model these as simple regulators with one bit on/off settings.

regulator: MAX8997/8966 support

2011-03-23T09:42:07Z

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.
