[PATCH v2 6/6] mfd: arizona: Update DT binding documentation for jack detection Charles Keepax <ckeepax@opensource.wolfsonmicro.com> - 2015-09-11 14:40 +0200

| Subject | [PATCH v2 6/6] mfd: arizona: Update DT binding documentation for jack detection |
| Message-ID | <q7vMu-1Di-5@gated-at.bofh.it> |
Add additional bindings for both inverting the polarity of the jack
detection pins and allowing the use of a second jack detection pin. Note
that the second jack detection pin is hard wired in the chip so can only
be enabled through the binding, rather than a pin being specified.
