2014-04-14regulator: s2mps11: Add external GPIO control for S2MPS14Krzysztof Kozlowski1-2/+65
Add support for external control over GPIO for LDO10, LDO11 and LDO12 S2MPS14 regulators. External control can be turned on by writing 0x0 to control register which in case of other regulators is used for disabling them. These LDO10-LDO12 regulators can be disabled only by I2C GPIO or PWREN pin so the patch actually allows proper way of disabling them. Additionally the GPIO control has two benefits: - It is faster than toggling it over I2C bus. - It allows disabling the regulator during suspend to RAM; The AP will enable it during resume.

2014-04-14regulator: core: Get and put regulator of_nodeCharles Keepax1-1/+2
Currently the regulator core does not take an additional reference to the of_node it is passed. This means that the caller must ensure that the of_node is valid for the duration of the regulator's existance. It is reasonable for the framework to assume it is passed a valid of_node but seems onerous for it to assume the caller will keep the node valid for the life-time of the regulator, especially when devm_regulator_register is used and there will likely be no code in the driver called at the point it would be safe to put the of_node. This patch adds an additional of_node_get when the regulator is registered and an of_node_put when it is unregistered in the core. This means individual drivers are free to put their of_node references at the end of probe letting the regulator core handling it from there. This simplifies code on the driver side.

2014-04-14regulator: core: Add helper to put of_nodes from matchesCharles Keepax1-0/+21
As of_regulator_match will take an of_node reference to each matched regulator, it makes sense to provide a helper to put all those references. This patch does that. Signed-off-by: Charles Keepax <[email protected]> Signed-off-by: Mark Brown <[email protected]>
2014-04-14regulator: core: Add of_node_get to of_regulator_matchCharles Keepax1-2/+3
Currently, of_regulator_match does not increment the reference count of the of_nodes it takes new references to. This could cause the node pointer held to be invalid, by the time it is passed to the regulator core. This patchs adds an of_node_get when we copy each of_node pointer into the match structure.

2014-04-07regulator: s5m8767: Fix carried over ena_gpio assignmentKrzysztof Kozlowski1-0/+1
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.

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.
