#1225971 — [PATCH 0/6] Arizona Extcon Update Device Bindings

Hi,

This patch chain adds device bindings for the jack and
microphone detection system specific settings.

Some of the bindings in this chain depend on features that
are being added in the following chain of patches:

Thanks,
Charles

#1225974 — [PATCH 2/6] extcon: arizona: Add device binding for the general purpose switch

The switch is generally used in conjunction with the MICDET clamp to
suppress pops and clicks associated with jack insertion. This patch adds
a binding that allows the user to select the mode of operation for this
switch.
