mfd: Use completion interrupt for WM831x AUXADC 2010-03-07T21:17:34+00:00 Mark Brown broonie@opensource.wolfsonmicro.com 2010-02-23T11:08:06+00:00 473fe73650b9f92114edbedfbb616561c1a0026c Use the completion interrupt generated by the device rather than polling for conversions to complete. As a backup we still check the status of the AUXADC if we don't get a completion, mostly for systems that don't have the WM831x interrupt infrastructure hooked up. Also reduce the timeout for completion of conversions to 5ms from the previous 10ms, the lower timeout should be sufficient.

mfd: Add WM831x revision B support 2010-03-07T21:17:29+00:00 Mark Brown broonie@opensource.wolfsonmicro.com 2010-02-17T18:45:25+00:00 f92e8f8144243a3651b2e350b706ea2d04931f8c Revision B of the WM831x devices changes the sense of the tristate bit for GPIO configuration, inverting it to become an enable instead. Take account of this in the gpiolib driver. A current sink regulation status bit has also been added in revision B, add a flag indicating if it's present but don't use it yet. This revision also adds an interrupt on key up for the ON pin event which the existing code is able to take advantage of.
