ASoC: Dynamically allocate the rtd device for a non-empty release()

2012-01-10T22:53:56+00:00

The device model needs a release() function so it can free devices when
they become dereferenced.  Do that for rtds.

ASoC: Declare soc_new_pcm() properly

2011-12-22T17:34:25+00:00

Ensure that everything is seeing the same declaration by moving it to
a header file rather than putting the declaration in soc-core.c

ASoC: Allow DAI links to be specified using device tree nodes

2011-12-22T11:00:21+00:00

DAI link endpoints and platform (DMA) devices are currently specified
by name. When instantiating sound cards from device tree, it may be more
convenient to refer to these devices by phandle in the device tree, and
for code to describe DAI links using the "struct device_node *"
("of_node") those phandles map to.

This change adds new fields to snd_soc_dai_link which can "name" devices
using of_node, enhances soc_bind_dai_link() to allow binding based on
of_node, and enhances snd_soc_register_card() to ensure that illegal
combinations of name and of_node are not used.

ASoC: Add utility to parse DAPM routes from device tree

2011-12-20T01:05:34+00:00

Implement snd_soc_of_parse_audio_routing(), a utility function that can
parses a simple DAPM route table from device tree.The machine driver
specifies the DT property to use, since this is binding-specific.

ASoC: Add utility to set a card's name from device tree

2011-12-20T01:05:34+00:00

Implement snd_soc_of_parse_card_name(), a utility function that sets a
card's name from device tree. The machine driver specifies the DT
property to use, since this is binding-specific.

ASoC: Remove rbtree register cache

2011-12-12T16:20:28+00:00

All users now use regmap directly so delete the ASoC version of the code.

ASoC: Drop unused state parameter from CODEC suspend callback

2011-12-02T10:32:03+00:00

The existence of this parameter is purely historical. None of the CODEC drivers
uses it and we always pass in the same value anyway, so it should be safe to
remove it.

ASoC: Implement fully_routed card property

2011-11-23T21:34:54+00:00

A card is fully routed if the DAPM route table describes all connections on
the board.

When a card is fully routed, some operations can be automated by the ASoC
core. The first, and currently only, such operation is described below, and
implemented by this patch.

Codecs often have a large number of external pins, and not all of these pins
will be connected on all board designs. Some machine drivers therefore call
snd_soc_dapm_nc_pin() for all the unused pins, in order to tell the ASoC core
never to activate them.

However, when a card is fully routed, the information needed to derive the
set of unused pins is present in card->dapm_routes. In this case, have
the ASoC core automatically call snd_soc_dapm_nc_pin() for each unused
codec pin.

This has been tested with soc/tegra/tegra_wm8903.c and soc/tegra/trimslice.c.

ASoC: Remove LZO cache type

2011-11-10T13:08:09+00:00

There are no current users and new drivers ought to be using the regmap
API and its cache implementation directly so just delete the ASoC copy.

ASoC: Remove extra space in runtime struct definition

2011-11-10T11:46:13+00:00

My usual technique for finding definitions is to search for "name {"
which breaks with the extra space.
