When it writes some value other than 0 to BTLDset and JIGset, muic device will be reset automatically. And it happens during updating ADC debounce time, because it shares same register.

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.

2014-04-23extcon: max14577: Add support for MAX77836Krzysztof Kozlowski2-21/+92
Add support for MAX77836 chipset to the max14577 extcon driver. The MAX77836 MUIC has additional interrupts (VIDRM, ADC1K) so IRQ handling is split up into two functions: max14577_parse_irq() and max77836_parse_irq().
