2013-09-20regulator: core: Fix default return value for _get()Mark Brown1-1/+1
Now that we are defaulting to providing dummy regulators fix the logic for substituting a dummy by making the default return code -EPROBE_DEFER. Reported-by: Thierry Reding <treding@nvidia.com> Tested-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-09-20regulator: core: set current constraints while setting machine constraintsLaxman Dewangan1-0/+34
Machine constraints is configured during regulator register. If current constraints are provided through machine constraints then it is observed that sometime the current configured on rail is out of range what machine constraint has. Set the current constraints when setting machine constraints to make sure that rail's current is within the range of given machine constraints.

2013-09-19regulator: wm8350: correct the max_uV of LDOLaxman Dewangan1-1/+1
As per datasheet, voltage range for LDOs are as follows: 0000 = 0.9V ...(50mV steps) 01111 = 1.65V 10000 = 1.8V ... (100mV stepns) 11111 = 3.3V So, there is no selector for 1.65V to 1.8V. Correcting the range for max_uV for selector between 0 to 15. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-09-18regulator: core: add support for configuring turn-on time through constraintsLaxman Dewangan2-0/+8
The turn-on time of the regulator depends on the regulator device's electrical characteristics. Sometimes regulator turn-on time also depends on the capacitive load on the given platform and it can be more than the datasheet value. The driver provides the enable-time as per datasheet. Add support for configure the enable ramp time through regulator constraints so that regulator core can take this value for enable time for that regulator.

2013-09-17regulator: palmas: Remove wrong comment for the equation calculating num_voltagesAxel Lin1-6/+0
Current equation on the comment is wrong. For linear mapping starting from 0, the equation is (maxV-minV)/stepV + 1. Since the linear mapping for PALMAS is not all starting from 0, the equation on the comment is not useful and misleading. Thus remove it.

2013-09-17regulator: palmas: configure enable time for LDOsLaxman Dewangan1-0/+6
As per datasheet (Referred TPS65913), the on-time for LDO is 500micro second. If LDO6 is in vibrator mode then the on-time is 2000us. Set the enable_time on regulator descriptor accordingly. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-09-17regulator: palmas: add support for external control of railsLaxman Dewangan1-6/+158
Palmas rails like LDOs, SMPSs, REGENs, SYSENs can be enable and disable by register programming through I2C communication as well as it can be enable/disable with the external control input ENABLE1, ENABLE2 and NSLEEP. Add support for configuring these rails to be controlled by external control inputs. This is require to configure the rail's control register as well as configuration of resource register. Provide the external input names through parameter "roof-floor". Updated the DT binding document to details different value of the roof-floor.

2013-09-17regulator: core: Remove unused regulator_use_dummy_regulator()Mark Brown1-17/+0
No boards have used this functionality and the new default of providing dummy regulators by default provides a better solution to the problem it was trying to solve. Signed-off-by: Mark Brown <broonie@linaro.org>
2013-09-17regulator: core: Provide a dummy regulator with full constraintsMark Brown2-27/+19
When a system has said that it has fully specified constraints for its regulators it is still possible that some supplies may be missing, especially if regulator support has been added to a driver after the board was integrated. We can handle such situations more gracefully by providing a dummy regulator. Unless the caller has specifically indicated that the system design may not include a given regulator by using regulator_get_optional() or that it needs its interactions to have an effect using regulator_get_exclusive() provide a dummy regulator if we can't locate a real one. The kconfig option REGULATOR_DUMMY that provided similar behaviour for all regulators has been removed, systems that need it should flag that they have full constraints instead.
