2014-03-10regulator: max1586: Remove regulator_dev pointer from state containerKrzysztof Kozlowski
Don't store pointer to regulator_dev returned by devm_regulator_register() in state container. It isn't used anywhere outside of max1586_pmic_probe() function. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-03-06regulator: helpers: Modify helpers enabling multi-bit controlCarlo Caione
This patch extends the regulator helpers to account for device that use multiple bits for control when using regmap enable/disable/bypass ops. The actual regulator helpers wrongly assume that the regulator control is always performed using single bits, using in the regulator_desc struct only two parameters *_reg and *_mask defining register and mask for control. This patch extends this struct and introduces the helpers to take into account devices where control is performed using multiple bits and specific multi-bit values are used for enabling/disabling/bypassing the regulator.

2014-03-04regulator: s2mps11: Fix section mismatchKrzysztof Kozlowski
Remove __initconst from regulator_desc array because this array is used during probe and s2mps11_pmic_probe() is not in __init section. However still select the number of supported regulators according to device ID so the driver will be ready for adding support for S2MPS14 device.

2014-03-03regulator: s2mps11: Copy supported regulators from initconstKrzysztof Kozlowski
Add __initconst to 'regulator_desc' array with supported regulators. During probe choose how many and which regulators will be supported according to device ID. Then copy the 'regulator_desc' array to allocated memory so the regulator core can use it. Additionally allocate array of of_regulator_match() dynamically (based on number of regulators) instead of allocation on the stack. This is needed for supporting different devices in s2mps11 driver and actually prepares the regulator driver for supporting the S2MPS14 device. Code for supporting the S2MPS14 device will add its own array of 'regulator_desc' (also marked as __initconst). This way memory footprint of the driver will be reduced (approximately 'regulators_desc' array for S2MPS11 occupies 5 kB on 32-bit ARM, for S2MPS14 will occupy 3 kB).

2014-02-25regulator: core: Replace direct ops->disable usageMarkus Pargmann
There are many places where ops->disable is called directly. Instead we should use _regulator_do_disable() which also handles gpio regulators. To be able to use the wrapper function from _regulator_force_disable(), I moved the _notifier_call_chain() call from _regulator_do_disable() to _regulator_disable(). This way, _regulator_force_disable() can use different flags for _notifier_call_chain() without calling it twice.

2014-02-25regulator: core: Replace direct ops->enable usageMarkus Pargmann
There are some direct ops->enable in the regulator core driver. This is a potential issue as the function _regulator_do_enable() handles gpio regulators and the normal ops->enable calls. These gpio regulators are simply ignored when ops->enable is called directly. One possible bug is that boot-on and always-on gpio regulators are not enabled on registration. This patch replaces all ops->enable calls by _regulator_do_enable.
