* regulator: msm: Add snapshot of the stub regulator driverDevesh Jhunjhunwala2016-03-23
| | | | | | | | | This is a snapshot of the Documentation and header file for the stub regulator driver as of msm-3.18 kernel commit: 2642c0adc79c06c0f3225da0177e910a1cea8cb5 ("Merge "ARM: dts: msm: Add support for truly 720p command mode panel on msmgold"") Signed-off-by: Devesh Jhunjhunwala <deveshj@codeaurora.org>
* regulator: core: put debugfs consumer handle when unregistering a regulatorDavid Collins2016-03-01
| | | | | | | | | | | Ensure that regulator_put() is called on the core debugfs consumer pointer for a given regulator when the debugfs interface is no longer needed. This includes inside of the regulator_unregister() function as well as in the error return path of rdev_init_debugfs().

* regulator: core: fix regulator bypass logicOsvaldo Banuelos2016-03-01
| | | | | | | | | | | | | Since the regulator debugfs consumer does not call regulator_allow_bypass() on its regulator handles, regulators will not be placed on bypass mode even if all other consumers request for this. Fix this by introducing an open offset count that can be used to selectively disregard the debugfs consumer. Also, introduce a debugfs file to allow or disallow bypass mode on each regulator by leveraging on the new open offset count.

* regulator: Call proxy-consumer functions for each regulator registeredDavid Collins2016-03-01
| | | | | | | | | | | | | | | | Add a call to regulator_proxy_consumer_register() at the end of regulator_register() and a call to regulator_proxy_consumer_unregister() at the beginning of regulator_unregister(). These calls ensure that proxy consumer features may be used by any type of regulator regardless of the driver supporting it.

Add another routine regulator_set_voltage_triplet(), which accepts target, min and max voltages as arguments. This first tries to set the voltage between the target voltage and the upper limit, then fall back on the full range. The idea behind this is to set regulator's voltage as close to the target voltage, as possible. Based on regulator_set_voltage_tol().

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().
