2012-12-24ASoC: tegra: add function to set ac97 rateLucas Stach
AC97 uses a fixed rate, unrelated to the sample rate. Add a function to make the setup more trivial. Signed-off-by: Lucas Stach <dev@lynxeye.de> Acked-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-04-06ASoC: tegra: utils: add support for Tegra30 devicesStephen Warren
Tegra30 has some additional clocks that need to be manipulated, names some clocks differently, runs PLLs at different base rates, etc. The utility code needs to handle this. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-04-20ASoC: Tegra: Don't return mclk_changed from utils_set_rateStephen Warren
Only the clock programming code needs to know whether the clocks changed, and that is encapsulated within tegra_asoc_utils_set_rate(). The machine driver's call to snd_soc_dai_set_sysclk(codec_dai, ...) is safe irrespective of whether the clocks changed. (Applying Mark's TrimSlice review comments to the existing driver) Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Liam Girdwood <lrg@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-01-31ASoC: Tegra: utils: Don't use global variablesStephen Warren
Instead, have the machine driver provide storage for the utility data somehow. For Harmony in particular, store this within struct tegra_harmony, itself referenced by snd_soc_card's drvdata.

2011-01-10ASoC: tegra: Machine utility codeStephen Warren
Many portions of Tegra ASoC machine drivers will be similar or identical. To avoid cut/paste, this file will act as a repository for all that common code. For now, it solely includes code to reprogram the audio PLL for 44.1KHz- vs. 48KHz-based sample rates.
