2015-05-19extcon: arizona: Add support for select accessory detect mode when headphone ↵Inha Song1-8/+30
detection This patch add support for select accessory detect mode to HPDETL or HPDETR. Arizona provides a headphone detection circuit on the HPDETL and HPDETR pins to measure the impedance of an external load connected to the headphone. Depending on board design, headphone detect pins can change to HPDETR or HPDETL.

2014-07-23extcon: arizona: Get MICVDD against extcon deviceCharles Keepax1-1/+1
Previously we would do a regulator get against the main Arizona device to obtain the MICVDD regulator. Arizona is an MFD device and normally MICVDD will be supplied by one of its children (the arizona-micsupp regulator). As devres destruction for the MFD device will run after all its children have been destroyed, the regulator will be destroyed before devres calls regulator_put. This causes a warning from both the destruction of the child node, as the regulator is still open, and from the put of the regulator as the regulator device has already been destroyed. A simple fix here is to get the regulator against the extcon device itself such that devres runs when the child is destroyed. This has the additional benefit that if for some reason the extcon driver is unloaded the regulator reference won't hang around until the MFD is unloaded.
