From 36a86872964609f2596d22f323070b60b17e08ef Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Thu, 19 Nov 2015 15:45:40 +0000 Subject: extcon: arizona: Update DT binding documentation for jack detection 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.
