2012-04-06ASoC: tegra: rename Tegra20-specific driver filesStephen Warren
Rename these files so they include a specific hardware version in their filenames. The contents is only touched minimally so that git's rename tracking operates correctly; renaming all symbols in the files results in a diff so large that the rename detection fails.

2011-12-08ASoC: Tegra: Move DAS configuration into DAS driverStephen Warren
Move DAS routing setup into the DAS driver itself. This removes the need to duplicate this in each machine driver, of which we'll soon have three. An added advantage is that the machine drivers no longer call the Tegra20- specific DAS functions by name, so the machine driver no longer needs to be split up into Tegra20 and Tegra30 versions. If individual machine drivers need a different routing setup to this default, they can still call the DAS functions to set that up. Long-term, DAS will be a codec driver, and user-space will be able to control its routing, possibly within constraints that the machine driver sets up. Configuring the DAS routing from the DAS driver is a very slight move in that direction.

2011-11-23ASoC: Tegra DAS: Use devm_ APIs and module_platform_driverStephen Warren
module_platform_drive saves some boiler-plate code. The devm_ APIs remove the need to manually clean up allocations, thus removing some code. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2011-02-13ASoC: Tegra: Add MODULE_ALIASStephen Warren
With the appropriate MODULE_ALIAS in place, the audio modules will be automatically loaded; there is no longer a need for manual modprobes. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-01-10ASoC: Update name of debugfs root symbol to snd_soc_Mark Brown
Everything else is using snd_soc_ so we should use it here too. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>
2011-01-10ASoC: tegra: Add tegra-das driverStephen Warren
The DAS (Digital Audio Switch) is a mux/crossbar which sits between the DACs (Digital Audio Controllers) and the DAPs (Digital Audio Ports). Audio data may be routed between DACs and DAPs in various combinations as required by board design/application.
