From 50dfb69d1bb0062e2811547525c73e9a45a423e9 Mon Sep 17 00:00:00 2001 From: Jarkko Nikula Date: Mon, 26 May 2014 14:34:36 +0300 Subject: [PATCH] ASoC: jack: Basic GPIO descriptor conversion This patch does basic GPIO descriptor conversion to soc-jack. Even the GPIOs are still passed and requested using legacy GPIO numbers the driver internals are converted to use GPIO descriptor API. Motivation for this is to prepare soc-jack so that it will allow registering jack GPIO pins using both GPIO descriptors and legacy GPIO numbers.
