From f025d3b9c64e1f7feb75a559d4a12f5f8c6a4a25 Mon Sep 17 00:00:00 2001 From: Jarkko Nikula Date: Mon, 26 May 2014 14:34:37 +0300 Subject: ASoC: jack: Add support for GPIO descriptor defined jack pins Allow jack GPIO pins be defined also using GPIO descriptor-based interface in addition to legacy GPIO numbers. This is done by adding two new fields to struct snd_soc_jack_gpio: idx and gpiod_dev. Legacy GPIO numbers are used only when GPIO consumer device gpiod_dev is NULL and otherwise idx is the descriptor index within the GPIO consumer device. New function snd_soc_jack_add_gpiods() is added for typical cases where all GPIO descriptor jack pins belong to same GPIO consumer device. For other cases the caller must set the gpiod_dev in struct snd_soc_jack_gpio before calling snd_soc_jack_add_gpios().
