[PATCH 0/2] SOF: Intel: hda: allow operation without i915 gfx
by Kai Vehmanen 20 Feb '20

Hi, here's a pair of patches that fixes SOF HDA driver load on devices that have: - digital mics connected to Intel HDA (so that SOF needs to be used instead of the legacy HDA driver), and - external GPU (internal i915 graphics not enabled) Kai Vehmanen (2): ASoC: intel/skl/hda - add no-HDMI cases to generic HDA driver ASoC: SOF: Intel: hda: allow operation without i915 gfx sound/soc/intel/boards/skl_hda_dsp_common.h | 4 ++++ sound/soc/intel/boards/skl_hda_dsp_generic.c | 25 ++++++++++++++++---- sound/soc/sof/intel/hda-codec.c | 11 ++++++++- sound/soc/sof/intel/hda.c | 22 +++++++---------- 4 files changed, 42 insertions(+), 20 deletions(-) -- 2.17.1

[PATCH] ASoC: pcm512x: Fix unbalanced regulator enable call in probe error path
by Matthias Reichl 20 Feb '20

20 Feb '20

When we get a clock error during probe we have to call regulator_bulk_disable before bailing out, otherwise we trigger a warning in regulator_put. Fix this by using "goto err" like in the error cases above.

Applied "dt-bindings: sound: Add TLV320ADCx140 dt bindings" to the asoc tree
by Mark Brown 20 Feb '20

20 Feb '20

The patch dt-bindings: sound: Add TLV320ADCx140 dt bindings has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

[PATCH] ASoC: tas2562: Add support for digital volume control
by Dan Murphy 20 Feb '20

20 Feb '20

Add support for digital volume control. There is no dedicated register for volume control but instead there are 4. The values of the registers are determined with exponential floating point math. So a table was created with register values for 2dB step increments from -110dB to 0dB.
