2012-04-03regulator: fixed: Support for open drain gpio pinLaxman Dewangan
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.

2009-09-22regulator: Add GPIO enable control to fixed voltage regulator driverRoger Quadros
Now fixed regulators that have their enable pin connected to a GPIO line can use the fixed regulator driver for regulator enable/disable control. The GPIO number and polarity information is passed through platform data. GPIO enable control is achieved using gpiolib.

2008-07-30regulator: fixed regulator interfaceMark Brown
This patch adds support for fixed regulators. This class of regulator is not software controllable but can coexist on machines with software controlable regulators. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lg@opensource.wolfsonmicro.com>
