ASoC: wm9713: add ac97 new bus support

2017-09-19T16:09:35+00:00

Add support for the new ac97 bus model, where devices are automatically
discovered on AC-Links.

ASoC: dapm: Support second register for DAPM control updates

2016-11-02T15:55:03+00:00

To support double channel shared controls split across 2 registers, one
for each channel, we must be able to update both registers together.

Add a second set of register fields to struct snd_soc_dapm_update, and
update the DAPM control writeback (put) callbacks to support this.

For codecs that use custom events which call into DAPM to do updates,
also clear struct snd_soc_dapm_update before using it, so the second
set of fields remains clean.

ASoC: constify snd_soc_codec_driver structures

2016-09-01T19:55:31+00:00

Check for snd_soc_codec_driver structures that are only passed to
snd_soc_register_codec or memcpy (2nd arg), for which the corresponding
parameters are declared const.  Declare as const snd_soc_codec_driver
structures that have these properties.

The semantic patch that makes this change is as follows:

ASoC: codec duplicated callback function goes to component on wm9713

2016-08-08T10:57:57+00:00

codec driver and component driver has duplicated callback functions,
and codec side functions are just copied to component side when
register timing. This was quick-hack, but no longer needed.
This patch moves these functions from codec driver to component driver.

ASoC: wm9713: fix regmap free path

2016-02-24T03:43:06+00:00

In the conversion to regmap, I assumed that the devm_() variant could be
used in the soc probe function.

As a mater of fact with the current code the regmap is freed twice
because of the devm_() call:
(mutex_lock) from [] (debugfs_remove_recursive+0x50/0x1d0)
(debugfs_remove_recursive) from [] (regmap_debugfs_exit+0x1c/0xd4)
(regmap_debugfs_exit) from [] (regmap_exit+0x28/0xc8)
(regmap_exit) from [] (release_nodes+0x18c/0x204)
(release_nodes) from [] (device_release+0x18/0x90)
(device_release) from [] (kobject_release+0x90/0x1bc)
(kobject_release) from [] (wm9713_soc_remove+0x1c/0x24)
(wm9713_soc_remove) from [] (soc_remove_component+0x50/0x7c)
(soc_remove_component) from [] (soc_remove_dai_links+0x118/0x228)
(soc_remove_dai_links) from [] (snd_soc_register_card+0x4e4/0xdd4)
(snd_soc_register_card) from [] (devm_snd_soc_register_card+0x34/0x70)

Fix this by replacing the devm_regmap initialization code with the non
devm_() variant.

ASoC: wm9713: use snd_soc_*() calls to update ac97 registers

2015-11-16T10:18:30+00:00

Convert wm9713 to use the more modern registers manipulation functions,
such as snd_soc_read(), snd_soc_write() and snd_soc_update_bits().

ASoC: wm9713: convert to regmap

2015-11-16T10:18:30+00:00

Convert the Wolfson WM9713 to regmap API. This will leverage all the
regmap functions (debug, registers update, etc ...).

As a bonus, this will pave the path to gpio chip introduction, and
devicetree support. This was tested on the mioa701 board, pxa27x based,
in PCM playback, and through suspend/resume.

ASoC: wm9713: Replace TLV_DB_RANGE_HEAD with DECLARE_TLV_DB_RANGE

2015-08-05T12:24:38+00:00

DECLARE_TLV_DB_RANGE() has the advantage over using TLV_DB_RANGE_HEAD()
that it automatically calculates the number of items in the TLV and is
hence less prone to manual error.

Generate using the following coccinelle script

//

snd_soc_new_ac97_codec() to perform the device reset rather than
open-coding it.
