[PATCH 0/6] Suspend related fixes on Tegra
by Sameer Pujar 27 Nov '21

27 Nov '21

This series addresses following problems: * The runtime PM is not balanced in MVC driver, whenever mute or volume mixer controls are set. * Some of the AHUB devices (SFC, MVC, Mixer, AMX and ADX) use late system sleep. Suspend failure is seen on Jetson TX2 platform.

[PATCH v4 0/3] ALSA: hda: New NHLT functions and cleanup
by Cezary Rojewski 26 Nov '21

26 Nov '21

Changes add two crucial functions: endpoint presence-check and retrieval of endpoint's BLOB (hardware configuration) to NHLT API. Outside of that, "is DMIC in NHLT?" check is being re-visited. No need to check for channel count or anything DMIC-configuration related, just straight up verify link_type presence. Changes in v4: - patch renaming nhlt_acpi_table struct to acpi_nhlt_table has been dropped due to naming conflicts with other parts of the kernel - revoked previously appended tags from Mark and Pierre as every patch required an update due to above Changes in v3: - no code changes - appended Mark's Acked-by tag for patch 4/4 - appended Pierre's Reviewed-by tag for all patches Changes in v2: - patch "ALSA hda: Drop device-argument in NHLT functions" has been dropped - updated newly added declarations in intel-nhlt.h so warning: "no-previous-prototype-for-function" and error: "use-of-undeclared-identifier" are no longer observed when CONFIG_SND_INTEL_NHLT is not enabled - added Mark's tag to the last patch of the series Amadeusz Sławiński (3): ALSA: hda: Fill gaps in NHLT endpoint-interface ALSA: hda: Simplify DMIC-in-NHLT check ASoC: Intel: Skylake: Use NHLT API to search for blob include/sound/intel-nhlt.h | 37 +++++++-- sound/hda/intel-dsp-config.c | 2 +- sound/hda/intel-nhlt.c | 102 +++++++++++++++++++++++++ sound/soc/intel/skylake/skl-nhlt.c | 102 ------------------------- sound/soc/intel/skylake/skl-pcm.c | 3 + sound/soc/intel/skylake/skl-topology.c | 29 ++++--- sound/soc/intel/skylake/skl-topology.h | 1 + sound/soc/intel/skylake/skl.h | 4 - 8 files changed, 153 insertions(+), 127 deletions(-) -- 2.25.1

[PATCH v3 0/4] ALSA: hda: New NHLT functions and cleanup
by Cezary Rojewski 26 Nov '21

26 Nov '21

Changes add two crucial functions: endpoint presence-check and retrieval of endpoint's BLOB (hardware configuration) to NHLT API. Few cleanups accompany the above: Work is done to align NHLT-struct naming with other, commonly used ACPI-structs. While cleaning up, don't forget about "is DMIC in NHLT?" check. No need to check for channel count or anything DMIC-configuration related, just straight up verify link_type presence. Changes in v3: - no code changes - appended Mark's Acked-by tag for patch 4/4 - appended Pierre's Reviewed-by tag for all patches Changes in v2: - patch "ALSA hda: Drop device-argument in NHLT functions" has been dropped - updated newly added declarations in intel-nhlt.h so warning: "no-previous-prototype-for-function" and error: "use-of-undeclared-identifier" are no longer observed when CONFIG_SND_INTEL_NHLT is not enabled - added Mark's tag to the last patch of the series Amadeusz Sławiński (4): ALSA: hda: Follow ACPI convention in NHLT struct naming ALSA: hda: Fill gaps in NHLT endpoint-interface ALSA: hda: Simplify DMIC-in-NHLT check ASoC: Intel: Skylake: Use NHLT API to search for blob include/sound/intel-nhlt.h | 53 ++++++++---- sound/hda/intel-dsp-config.c | 4 +- sound/hda/intel-nhlt.c | 110 ++++++++++++++++++++++++- sound/soc/intel/skylake/skl-nhlt.c | 108 +----------------------- sound/soc/intel/skylake/skl-pcm.c | 3 + sound/soc/intel/skylake/skl-topology.c | 29 ++++--- sound/soc/intel/skylake/skl-topology.h | 1 + sound/soc/intel/skylake/skl.h | 6 +- sound/soc/sof/intel/hda.c | 2 +- 9 files changed, 171 insertions(+), 145 deletions(-) -- 2.25.1
