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.

Hence to get the regulator node, the correct call is of_get_child_by_name() rather than of_find_node_by_name() which searches the "regulators" node from the parent node to end of DTS file.

Moving regulator node parsing to regulator driver in place of parsing it on mfd driver. The motivation for this change are: - MFD core driver should not depends on regulator and able to instantiate device without regulator. - The API for matching regulators are in regulator core and it is good that regulator driver only calls this API. - Regulator specific support should be in regulator driver only to ease any enhancement/modification for regulators. - The regulator driver is now registered as mfd sub device and all regulator registration is done from single probe call.

Rather than adding new arguments to regulator_register() every time we want to add a new bit of dynamic information at runtime change the function to take these via a struct. By doing this we avoid needing to do further changes like the recent addition of device tree support which required each regulator driver to be updated to take an additional parameter.
