2014-04-14regulator: pbias: Convert to use regmap helper functionsAxel Lin
This patch converts this driver to use the regmap helper functions provided by regulator core. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Balaji T K <balajitk@ti.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-04-14regulator: pbias: Fix is_enabled callback implementationAxel Lin
The is_enabled implementation is wrong in some cases: e.g. for pbias_mmc_omap5: enable_mask is : BIT(27) | BIT(25) | BIT(26) However, pbias_regulator_enable() only sets BIT(27) | BIT(26) bits. So is_enabled callback will always return false in this case. Fix the logic to compare the register value with info->enable rather than info->enable_mask.

2014-04-07regulator: s5m8767: Fix carried over ena_gpio assignmentKrzysztof Kozlowski
During registration of regulators if external control for regulator was set in DTS the ena_gpio and ena_gpio_flags fields of regulator_config were set to proper values. However the same regulator_config was used in next iterations of loop so the ena_gpio fields carried over to next regulators. The issue was not observed as ena_gpio is supported only for Buck9 regulator which is often the last regulator parsed from DTS. Be sure to clear ena_gpio config fields before registering the regulator.

2014-03-18regulator: anatop: Remove checking control_reg in [set|get]_voltage_selAxel Lin
Remove checking control_reg in [set|get]_voltage_sel and then convert to use regulator_[set|get]_voltage_sel_regmap for [set|get]_voltage_sel callbacks. The anatop-reg-offset property is a required property rather than optional property. So the question is what is the meaning of setting anatop-reg-offset to 0? If 0 is a valid setting for anatop-reg-offset and it has special meaning, we had better document it in the binding document. Otherwise, remove the testing for control_reg in the driver. No anatop voltage regulator node in the dts files set anatop-reg-offset to 0. So I think it's safe to remove testing if control_reg is 0.
