2014-03-10regulator: max77686: Remove regulator_dev array from state containerKrzysztof Kozlowski
Don't store array of regulator_dev returned by devm_regulator_register() in state container. It isn't used anywhere outside of max77686_pmic_probe() function. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2014-02-14regulator: max77686: Use of_get_child_by_nameSachin Kamat
of_find_node_by_name walks the allnodes list, and can thus walk outside of the parent node. Use of_get_child_by_name instead. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Mark Brown <broonie@linaro.org>

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.

2013-01-27regulator: max77686: Fix using wrong dev argument at various placesAxel Lin
Use &pdev->dev rather than iodev->dev for dev_err(). Use &pdev->dev rather than iodev->dev for devm_kzalloc() and of_regulator_match(), this fixes memory leak. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2012-10-22regulator: max77686: Make max77686_enable() static.Yadwinder Singh Brar
This patch fixes a sparse warning. Since max77686_enable() is a callback,so it should be static. Signed-off-by: Yadwinder Singh Brar <yadi.brar@samsung.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-10-17regulator: max77686: Add set_suspend_disable/set_suspend_mode callbacks.Yadwinder Singh Brar
This patch implements set_suspend_disable callback for BUCKs which support only switch ON/OFF modes during system suspend state, and set_suspend_mode callbacks for LDOs which also suport Low power mode and switch ON/OFF modes.

2012-07-05regulator: max77686: Add device tree support.Yadwinder Singh Brar

2012-06-19regulator: max77686: Convert driver to use regulator_set_voltage_time_sel.Yadwinder Singh Brar
This patch converts the driver to use regulator_set_voltage_time_sel() as .set_voltage_time_sel() callback. It also sets ramp_delay as 100000 uV/us for LDOs & normal BUCKs and 27500 uV/us(default/reset value) for BUCKs[2/3/4] in regulator_desc[].
