2020-04-21ASoC: tegra: Use device managed resource APIs to get the clockSowjanya Komatineni1-1/+0
tegra_asoc_utils uses clk_get() to get the clock and clk_put() to free them explicitly. This patch updates it to use device managed resource API devm_clk_get() so the clock will be automatically released and freed when the device is unbound and removes tegra_asoc_utils_fini() as its no longer needed.

2013-10-14ASoC: tegra: support new register layouts in Tegra124Stephen Warren1-0/+1
Tegra124 introduces some small changes to the layout of some registers. Modify the affected drivers to program those registers appropriately based on which SoC they're running on. Tegra124 also introduced some new modules on the AHUB configlink register bus. These will require new entries in configlink_clocks[] in the AHUB driver. However, supporting that change likely relies on switching Tegra to the common reset framework, so I'll defer that change for now.

2013-03-25ASoC: tegra: add Tegra114 support to tegra_asoc_utils.cStephen Warren1-0/+1
Tegra114 requires different PLL rates. Modify the code to know about this. On Tegra114 only for now, use regular clk_get() rather than clk_get_sys() to retrieve clocks. This assumes that the clocks will be represented in device tree. We can assure that from the start of any Tegra114 audio support. For older chips, I'll add the required clocks properties to the device trees this kernel cycle, and switch this code to only support the "new_clocks" path next cycle.

2012-12-24ASoC: tegra: add function to set ac97 rateLucas Stach1-0/+1
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 Warren1-2/+7
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 Warren1-1/+1
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.

2011-01-31ASoC: Tegra: utils: Don't use global variablesStephen Warren1-3/+17
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.

2011-01-11ASoC: tegra: Machine utility codeStephen Warren1-0/+31
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.
