2015-02-05regulator: max77843: Add max77843 regulator driverJaewon Kim3-0/+236
This patch adds new regulator driver to support max77843 MFD(Multi Function Device) chip`s regulators. The Max77843 has two voltage regulators for USB safeout.

2015-02-02regulator: Build sysfs entries with static attribute groupsTakashi Iwai1-127/+108
Instead of calling device_create_file() manually after the device registration, put all in attribute groups and filter the unwanted ones via is_visible callback. This not only simplifies the code but also avoids the possible race between the device registration and sysfs registration.

2015-01-08regulator: Allow parsing custom properties when using simplified DT parsingKrzysztof Kozlowski3-1/+14
When drivers use simplified DT parsing method (they provide 'regulator_desc.of_match') they still may want to parse custom properties for some of the regulators. For example some of the regulators support GPIO enable control. Add a driver-supplied callback for such case. This way the regulator core parses common bindings offloading a lot of code from drivers and still custom properties may be used. The callback, called for each parsed regulator, may modify the 'regulator_config' initially passed to regulator_register().

Add enable control over GPIO for regulators supporting this: LDO20, LDO21, LDO22, buck8 and buck9. This is needed for proper (and full) configuration of the Maxim 77686 PMIC without creating redundant 'regulator-fixed' entries.

2015-01-08regulator: Copy config passed during registrationKrzysztof Kozlowski1-3/+15
Copy the 'regulator_config' structure passed to regulator_register() function so the driver could safely modify it after parsing init data. The driver may want to change the config as a result of specific init data parsed by regulator core (e.g. when core handled parsing device tree).

2015-01-08regulator: core: fix race condition in regulator_put()Ashay Jaiswal1-1/+3
The regulator framework maintains a list of consumer regulators for a regulator device and protects it from concurrent access using the regulator device's mutex lock. In the case of regulator_put() the consumer is removed and regulator device's parameters are updated without holding the regulator device's mutex. This would lead to a race condition between the regulator_put() and any function which traverses the consumer list or modifies regulator device's parameters. Fix this race condition by holding the regulator device's mutex in case of regulator_put.
