From ca9c1aaec4187fc9922cfb6b283fffef89286943 Mon Sep 17 00:00:00 2001 From: Ian Molton Date: Tue, 6 Jan 2009 20:11:51 +0000 Subject: ASoC: dapm: Allow explictly named mixer controls This patch allows you to define the mixer paths as having the same name as the paths they represent. This is required to support codecs such as the wm9705 neatly without extra controls in the alsa mixer.

This wraps the ALSA core jack detection functionality and provides integration with DAPM to automatically update the power state of pins based on the jack state. Since embedded platforms can have multiple detecton methods used for a single jack (eg, separate microphone and headphone detection) the report function allows specification of which bits are being updated on a given report. The expected usage is that machine drivers will create jack objects and then configure jack detection methods to update that jack.

The gpio support exports two new functions: snd_soc_jack_add_gpios and snd_soc_jack_free_gpios. Client drivers using gpio feature must pass an array of jack_gpio pins belonging to a specific jack to the snd_soc_jack_add_gpios function. The framework will request the gpios, set the data direction and request irq. The framework will update power status of related jack_pins when an event on the gpio pins comes according to the reporting bits defined for each gpio. All gpio resources allocated when adding jack_gpio pins can be released using snd_soc_jack_free_gpios function.
