2014-01-31regulator: s2mps11: Fix NULL pointer of_node value when using platform dataKrzysztof Kozlowski
When platform_data is used for regulator (of_node of sec-core MFD device is NULL) the config.of_node for regulator is not initialized. This NULL value of config.of_node is later stored during regulator_register(). Thus any call by regulator consumers to of_get_regulator() will fail on of_parse_phandle() returning NULL. In this case (using platform_data and parent's driver of_node is NULL) set the config.of_node to reg_node from platform_data.

BUCK 3 and 4 share the same ramp delay. Hence make it a fall through case instead of duplicating the code. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Mark Brown <broonie@linaro.org>

2013-09-16regulator: s2mps11: Use devm_regulator_registerSachin Kamat
Commit e398b51a ("regulator: s2mps11: Convert to devm_regulator_register()") intended to do this conversion. However the actual conversion to devm_* got missed out. Fix this. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Mark Brown <broonie@linaro.org>

2013-08-13regulator: s2mps11: Fix setting ramp_delayAxel Lin
Current code has wrong mask and val arguments for updating ramp_delay. Fix it. Also ensure the return value of get_ramp_delay() won't greater than 3 because the mask field for ramp_val only takes 2 bits. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2013-07-15regulator: s2mps11: Convert driver completely to use set_ramp_delay callbackYadwinder Singh Brar
Since now we have ramp_delay and ramp_disable as standard regulator constraints and DT part using it so this patch removes legacy part i.e. getting ramp_delayxx and ramp_enable from pdata since it can be passed as standard regulator constraints.

2013-07-15regulator: s2mps11: Add DT supportYadwinder Singh Brar
This patch adds DT support for parsing regulators constraints for parent(mfd) node and moves some common intialising code out of loop while registering. Signed-off-by: Yadwinder Singh Brar <yadi.brar@samsung.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-07-15regulator: s2mps11: Implement set_ramp_rate callback for bucksYadwinder Singh Brar
Implementing set_ramp_rate() and using standard constraints for getting ramp_delay and ramp_disable, instead of getting it as s2mps11 specific data through platform data, makes driver more compliant with framework and reduces the complexity for adding DT support.

2013-07-15regulator: s2mps11: Implement set_voltage_time_sel() ops for bucksYadwinder Singh Brar
Currently driver uses local struct s2mps11_info to store ramp rate for bucks whic its getting through platform data, so instead of using regulator constraints it should use s2mps11_info to calculate ramp delay.

2013-07-03regulator: s2mps11: Convert ramp rate to uV/us and set default ramp rateYadwinder Singh Brar
This patch makes driver to use uV/us as units of ramp_delay. It makes driver in compliance with regulator framework and make ramp rate precise. This patch also sets default ramp rate in regulator descriptor which can be used in case if case ramp rate is not set in regulator constraints.

2013-05-12regulator: Remove unnecessary include of linux/delay.h from regulator driversAxel Lin
All the drivers that need delay for the regulator voltage output voltage to stabilize after being enabled or after being set to a new value has been converted to implement enable_time and set_voltage_time_sel callbacks. Then regulator core will take care of the necessary delay. This patch removes the unneeded include of linux/delay.h in regulator drivers.
