ASoC: dt-bindings: qcom,q6dsp-lpass-ports: Rename QAIF clock IDs

2026-08-18T18:22:44+00:00

The QAIF clock IDs were introduced with a LAPSS prefix typo. Rename
them to use the existing LPASS naming convention and update all
corresponding in-tree users.

Since these IDs are new, rename them directly instead of keeping
backward-compatible aliases.

dt-bindings: sound: qcom,q6dsp-lpass-ports: add Audio IF clocks

2026-08-04T16:32:19+00:00

Add the LPASS Audio IF clock IDs used by newer backend interfaces.

Platforms using Audio IF module backends request the interface bit
clocks through q6prm. Add the Audio IF IBIT and EBIT IDs to the binding
header so these clocks can be referenced from device trees.

SDM660 sound card and internal MI2S support

2026-07-31T23:28:01+00:00

Richard Acayan  says:

This adds support for the SDM660 (formerly "SDM660 internal") sound card
and support for WCD codecs over internal MI2S (represented in APIs as
LPI MI2S).

Like on MSM8916 and MSM8953, some SDM660 and SDM670 devices connect to a
digital and analog codec. The connection to the digital codec is through
special "internal" MI2S ports. The digital and analog codecs are used on
the Xiaomi Redmi Note 7 for headset (playback + capture) and earpiece,
and also on the Google Pixel 3a for the headset.

This series does not include devicetree patches.

ASoC: dt-bindings: qcom: q6dsp: add support for lpi mi2s ports 5-6

2026-07-31T23:27:38+00:00

There are 7 internal MI2S ports per direction found on devices with the
internal sound card for Snapdragon 660. This is similar to the LPI MI2S
ports, and the LPI MI2S bindings can be reused for internal MI2S. Extend
the bindings for LPI MI2S ports to accommodate the internal MI2S ports.

ASoC: dt-bindings: qcom: add LPASS LPR vote clock ID

2026-07-31T23:07:27+00:00

Add a new clock ID, LPASS_HW_LPR_VOTE, to represent the LPASS low-power
resource (LPR) vote through the PRM interface.

The LPASS PRM supports a resource voting mechanism to control low-power
states via PARAM_ID_RSC_CPU_LPR. Exposing this as a q6prm clock ID allows
clients to request the LPR vote using the existing qcom,q6prm clock
provider interface.

This functionality is required on newer platforms (e.g. Hawi) where LPASS
clients need to explicitly manage LPR resource voting via PRM.

Merge tag 'usb-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

2025-06-06T19:45:35+00:00

Pull USB / Thunderbolt updates from Greg KH:
 "Here is the big set of USB and Thunderbolt changes for 6.16-rc1.
  Included in here are the following:

   - USB offload support for audio devices.

     I think this takes the record for the most number of patch series
     (30+) over the longest period of time (2+ years) to get merged
     properly.

     Many props go to Wesley Cheng for seeing this effort through, they
     took a major out-of-tree hacked-up-monstrosity that was created by
     multiple vendors for their specific devices, got it all merged into
     a semi-coherent set of changes, and got all of the different major
     subsystems to agree on how this should be implemented both with
     changes to their code as well as userspace apis, AND wrangled the
     hardware companies into agreeing to go forward with this, despite
     making them all redo work they had already done in their private
     device trees.

     This feature offers major power savings on embedded devices where a
     USB audio stream can continue to flow while the rest of the system
     is sleeping, something that devices running on battery power really
     care about. There are still some more small tweaks left to be done
     here, and those patches are still out for review and arguing among
     the different hardware companies, but this is a major step forward
     and a great example of how to do upstream development well.

   - small number of thunderbolt fixes and updates, things seem to be
     slowing down here (famous last words...)

   - xhci refactors and reworking to try to handle some rough corner
     cases in some hardware implementations where things don't always
     work properly

   - typec driver updates

   - USB3 power management reworking and updates

   - Removal of some old and orphaned UDC gadget drivers that had not
     been used in a very long time, dropping over 11 thousand lines from
     the tree, always a nice thing, making up for the 12k lines added
     for the USB offload feature.

   - lots of little updates and fixes in different drivers

  All of these have been in linux-next for over 2 weeks, the USB offload
  logic has been in there for 8 weeks now, with no reported issues"

ASoC: dt-bindings: Add Cirrus Logic CS48L32 audio DSP

2025-04-15T12:58:42+00:00

The CS48L32 is an Audio DSP with microphone inputs and SPI
control interface. It has a programmable DSP and a variety of
power-efficient fixed-function audio processors, with configurable
digital mixing and routing.

Most properties are core properties: supply regulators, gpios, clocks,
interrupt parent and SPI interface. The custom properties define
the configuration of the microphone inputs to match what is physically
attached to them.
