Pull sound updates from Takashi Iwai:
 "It's been relatively calm for a new era; majority of changes are for
  ASoC, mostly device-specific changes, while there are a bit of
  cleanups in core stuff. A few SPI API and regmap updates are included
  to be used by sound drivers, too.

  Core:
   - A few trivial cleanups about __free() and runtime PM macros
   - Convert to new snd_seq_bus binding

  ASoC:
   - Generic SDCA support for reporting jack events
   - Continuing platform support, cleanup and feature improvements for
     AMD, Intel, Qualcomm and SOF code
   - Platform description improvements for the Cirrus drivers
   - Support for NXP i.MX952, Realtek RT1320 and RT5575, and Sophogo
     CV1800B

  HD- and USB-audio:
   - Many quirks as usual"

ASoC: fsl_sai: Add AUDMIX mode support on i.MX952

2026-01-26T12:09:19+00:00

One of SAI interfaces is connected to AUDMIX in the i.MX952 chip, but
AUDMIX can be bypassed or not bypassed on the i.MX952 platform.

There are three use cases:
1) SAI -> Codec (No AUDMIX between SAI and Codec)
2) SAI -> Codec (Has AUDMIX, but AUDMIX is bypassed)
3) SAI -> AUDMIX -> Codec (Has AUDMIX and used)

So add 'fsl,sai-amix-mode' property for this feature

fsl,sai-amix-mode = "none": is for case 1)
fsl,sai-amix-mode = "bypass": is for case 2)
fsl,sai-amix-mode = "audmix": is for case 3)

firmware: qcom_scm: Add qcom_scm_pas_get_rsc_table() to get resource table

2026-01-13T18:14:34+00:00

Qualcomm remote processor may rely on Static and Dynamic resources for
it to be functional. Static resources are fixed like for example,
memory-mapped addresses required by the subsystem and dynamic
resources, such as shared memory in DDR etc., are determined at
runtime during the boot process.

For most of the Qualcomm SoCs, when run with Gunyah or older QHEE
hypervisor, all the resources whether it is static or dynamic, is
managed by the hypervisor. Dynamic resources if it is present for a
remote processor will always be coming from secure world via SMC call
while static resources may be present in remote processor firmware
binary or it may be coming qcom_scm_pas_get_rsc_table() SMC call along
with dynamic resources.

Some of the remote processor drivers, such as video, GPU, IPA, etc., do
not check whether resources are present in their remote processor
firmware binary. In such cases, the caller of this function should set
input_rt and input_rt_size as NULL and zero respectively. Remoteproc
framework has method to check whether firmware binary contain resources
or not and they should be pass resource table pointer to input_rt and
resource table size to input_rt_size and this will be forwarded to
TrustZone for authentication. TrustZone will then append the dynamic
resources and return the complete resource table in the passed output
buffer.

More about documentation on resource table format can be found in
include/linux/remoteproc.h

firmware: qcom_scm: Add a prep version of auth_and_reset function

2026-01-13T18:14:34+00:00

For memory passed to TrustZone (TZ), it must either be part of a pool
registered with TZ or explicitly registered via SHMbridge SMC calls.
When Gunyah hypervisor is present, PAS SMC calls from Linux running at
EL1 are trapped by Gunyah running @ EL2, which handles SHMbridge
creation for both metadata and remoteproc carveout memory before
invoking the calls to TZ.

On SoCs running with a non-Gunyah-based hypervisor, Linux must take
responsibility for creating the SHM bridge before invoking PAS SMC
calls. For the auth_and_reset() call, the remoteproc carveout memory
must first be registered with TZ via a SHMbridge SMC call and once
authentication and reset are complete, the SHMbridge memory can be
deregistered.

Introduce qcom_scm_pas_prepare_and_auth_reset(), which sets up the SHM
bridge over the remoteproc carveout memory when Linux operates at EL2.
This behavior is indicated by a new field added to the PAS context data
structure. The function then invokes the auth_and_reset SMC call.

remoteproc: pas: Replace metadata context with PAS context structure

2026-01-13T18:14:33+00:00

As a superset of the existing metadata context, the PAS context
structure enables both remoteproc and non-remoteproc subsystems to
better support scenarios where the SoC runs with or without the Gunyah
hypervisor. To reflect this, relevant SCM and metadata functions are
updated to incorporate PAS context awareness and remove metadata context
data structure completely.

firmware: qcom_scm: Introduce PAS context allocator helper function

2026-01-13T18:14:33+00:00

When the Peripheral Authentication Service (PAS) method runs on a SoC
where Linux operates at EL2 (i.e., without the Gunyah hypervisor), the
reset sequences are handled by TrustZone. In such cases, Linux must
perform additional steps before invoking PAS SMC calls, such as creating
a SHM bridge. Therefore, PAS SMC calls require awareness and handling of
these additional steps when Linux runs at EL2.

To support this, there is a need for a data structure that can be
initialized prior to invoking any SMC or MDT functions. This structure
allows those functions to determine whether they are operating in the
presence or absence of the Gunyah hypervisor and behave accordingly.

Currently, remoteproc and non-remoteproc subsystems use different
variants of the MDT loader helper API, primarily due to differences in
metadata context handling. Remoteproc subsystems retain the metadata
context until authentication and reset are completed, while
non-remoteproc subsystems (e.g., video, graphics, IPA, etc.) do not
retain the metadata context and can free it within the
qcom_scm_pas_init() call by passing a NULL context parameter and due to
these differences, it is not possible to extend metadata context
handling to support remoteproc and non remoteproc subsystem use PAS
operations, when Linux operates at EL2.

Add PAS context data structure allocator helper function.
