2014-09-24regulator/mfd: max14577: Export symbols for calculating charger currentKrzysztof Kozlowski1-76/+4
This patch prepares for changing the max14577 charger driver to allow configuring battery-dependent settings from DTS. The patch moves from regulator driver to MFD core driver and exports: - function for calculating register value for charger's current; - table of limits for chargers (MAX14577, MAX77836). Previously they were used only by the max14577 regulator driver. In next patch the charger driver will use them as well. Exporting them will reduce unnecessary code duplication.

2014-09-22regulator: axp20x: Use parent device as regulator configuration deviceMaxime Ripard1-1/+1
The current device used for the regulator configuration is the child device created by the MFD driver. This means that it doesn't have any of_node pointing to it, and whenever we register the regulators, it will not look into the regulator supply in the DT, hence requiring to provide regulator aliases in the MFD driver. We can easily fix that by using the parent device in our configuration, which has a DT node associated to it, and will allow a DT lookup. Eventually, we will be able to remove the aliases in the MFD driver. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2014-09-16regulator: fan53555: add support for Silergy SYR82x regulatorsHeiko Stuebner1-15/+87
Silergy SYR82x regulators share the exact same functionality and register layout as the Fairchild FAN53555 regulators. Therefore extend the driver to add support for them. Both types use the same vendor id in their ID1 register, so it's not possible to distinguish them automatically. Similarly, the types also do not match. Type 8 used by the SYR827 and SYR828 start at 712.5mV and increment in 12.5mv steps, while the FAN53555 type 8 starts at 600mV and increments in 10mV steps.

2014-09-10regulator: of: Provide simplified DT parsing methodMark Brown3-3/+62
Currently regulator drivers which support DT all repeat very similar code to supply a list of known regulator identifiers to be matched with DT, convert that to platform data which is then matched up with the regulators as they are registered. This is both fiddly to get right and for devices which can use the standard helpers to provide their operations is the main source of code in the driver. Since this code is essentially identical for most drivers we can factor it out into the core, moving the identifiers in the match table into the regulator descriptors and also allowing drivers to pass in the name of the subnode to search. When a driver provides an of_match string for the regulator the core will attempt to use that to obtain init_data, allowing the driver to remove all explicit code for DT parsing and simply provide data instead. The current code leaks the phandles for the child nodes, this will be addressed incrementally and makes no practical difference for FDT anyway as the DT data structures are never freed.
