From: Mark Brown Date: Thu, 10 Jan 2013 23:55:36 +0000 (+0900) Subject: extcon: arizona: Use microphone clamp function if available X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=dab63eb25ced7539a51b8f4218f7b6b56d34df22;p=linux-beck.git extcon: arizona: Use microphone clamp function if available Newer Arizona devices include a microphone clamp function which is tied to jack detect. Activate this feature when present in order to ensure best performance of the subsystem.
