2012-04-09regulator: core: Use a struct to pass in regulator runtime configurationMark Brown
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. The regulator_desc which should (mostly) be static data is still passed separately as most drivers are able to configure this statically at build time.

2012-04-06regulator: Convert rc5t583 to set_voltageAxel Lin
Not every regulator driver should implement set_voltage_sel callback. See commit e8eef82 "regulator: Provide a selector based set_voltage_sel() operation". For rc5t583, the regulator voltage can be mapped onto selector values with a simple calculation, thus implement set_voltage is better than set_voltage_sel.

Adding flag on fixed regulator board configuration structure to specify whether gpio is open drain type or not. Passing this information to gpio library when requesting gpio so that gpio driver can set the pin state accordingly, for open drain type: - Pin can be set HIGH as setting as input, PULL UP on pin make this as HIGH. - Pin can be set LOW as setting it as output and drive to LOW. The non-open drain pin can be set HIGH/LOW by setting it to output and driving it to HIGH/LOW.
