2014-02-22regulator: max14577: Fix invalid return value on DT parse successKrzysztof Kozlowski1-2/+3
This fixes bug introduced in 667a6b7a (regulator: max14577: Add missing of_node_put). The DTS parsing function returned number of matched regulators as success status which then was compared against 0 in probe. Result was a probe fail after successful parsing the DTS: max14577-regulator: probe of max14577-regulator failed with error 2 Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Reviwed-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Mark Brown <broonie@linaro.org>

2014-02-12regulator: da9063: Bug fix when setting max voltage on LDOs 5-11Steve Twiss1-1/+3
Bug fix to allow the setting of maximum voltage for certain LDOs. What the bug is: There is a problem caused by an invalid calculation of n_voltages in the driver. This n_voltages value has the potential to be different for each regulator. The value for linear_min_sel is set as DA9063_V##regl_name# which can be different depending upon the regulator. This is chosen according to the following definitions in the DA9063 registers.h file: DA9063_VLDO1_BIAS 0 DA9063_VLDO2_BIAS 0 DA9063_VLDO3_BIAS 0 DA9063_VLDO4_BIAS 0 DA9063_VLDO5_BIAS 2 DA9063_VLDO6_BIAS 2 DA9063_VLDO7_BIAS 2 DA9063_VLDO8_BIAS 2 DA9063_VLDO9_BIAS 3 DA9063_VLDO10_BIAS 2 DA9063_VLDO11_BIAS 2 The calculation for n_voltages is valid for LDOs whose BIAS value is zero but this is not correct for those LDOs which have a non-zero value. What the fix is: In order to take into account the non-zero linear_min_sel value which is set for the regulators LDO5, LDO6, LDO7, LDO8, LDO9, LDO10 and LDO11, the calculation for n_voltages should take into account the missing term defined by DA9063_V##regl_name#. This will in turn allow the core constraints calculation to set the maximum voltage limits correctly and therefore allow users to apply the maximum expected voltage to all of the LDOs.

2014-01-31regulator: s2mps11: Fix NULL pointer of_node value when using platform dataKrzysztof Kozlowski1-0/+1
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.

2014-01-28regulator: core: Correct default return value for full constraintsMark Brown1-1/+8
Once we have full constraints then all supply mappings should be known to the regulator API. This means that we should treat failed lookups as fatal rather than deferring in the hope of further registrations but this was broken by commit 9b92da1f1205bd25 "regulator: core: Fix default return value for _get()" which was targeted at DT systems but unintentionally broke non-DT systems by changing the default return value. Fix this by explicitly returning -EPROBE_DEFER from the DT lookup if we find a property but no corresponding regulator and by having the non-DT case default to -ENODEV when we have full constraints.

2014-01-21regulator: tps6586x: Add and use correct voltage tableStefan Agner1-19/+74
Depending on the regulator version, the voltage table might be different. Use version specific regulator tables in order to select correct voltage table. For the following regulator versions different voltage tables are now used: * TPS658623: Use correct voltage table for SM2 * TPS658643: New voltage table for SM2 Both versions are in use on the Colibri T20 module. Make use of the correct tables by requesting the correct SM2 voltage of 1.8V. This change is not backward compatible since an old driver is not able to correctly set that value. The value 1.8V is out of range for the old driver and will refuse to probe the device. The regulator starts with default settings and the driver shows appropriate error messages. On Colibri T20, the old value used to work with TPS658623 since the driver applied a wrong voltage table too. However, the TPS658643 used on V1.2 devices uses yet another voltage table and those broke that pseudo-compatibility. The regulator driver now has the correct voltage table for both regulator versions and those the correct voltage can be used in the device tree.
