Subject: [PATCH 04/11] extcon: arizona: Allow configuration of MICBIAS rise time
Date: Thu, 10 Jan 2013 12:04:15 +0000 [thread overview]
Message-ID: <1357819462-12232-4-git-send-email-broonie@opensource.wolfsonmicro.com> (raw)
In-Reply-To: <1357819462-12232-1-git-send-email-broonie@opensource.wolfsonmicro.com>
Allow configuration of the rise time for MICBIAS via platform data, the
delay required depends on things like the external component selection.
