[PATCH V2 0/9] soundwire: amd: introduce hw_ops dispatch and split driver into revision-specific files

[Vijendar Mukunda]

This is v2 of the AMD SoundWire manager driver refactor series. It
incorporates review feedback from v1 and extends the restructuring to
split the monolithic amd_manager.c into two files.

Changes since v1:
- Patch 4 subject updated: "rename hardware backend symbols" (covers
  functions, op-table instances, and the register-offset constant)
- Patch 6: removed the forward reference to "subsequent patches" from
  the commit message; dropped WARN_ONCE guards from dispatch helpers
- Patch 7: commit message corrected; #include <linux/workqueue.h>
  addition dropped (available transitively)
- Patch 8: amd_sdw_hw_init_ops() now uses a static const
  struct amd_sdw_hw_ops instead of devm_kzalloc; amd_sdw_hw_init_ops()
  moved after amd_sdw_manager_remove() with a forward declaration before
  probe to resolve ordering
- Patch 9 (new): splits amd_manager.c into amd_manager_common.c
  (shared revision-independent functions, analogous to cadence_master.c)
  and renames what remains to amd_acp63_manager.c (ACP6.3/7.x register-
  level backend, analogous to intel_auxdevice.c)

Series overview:

Patches 1-3 are preparatory: rename the manager-count macro to carry
the ACP6.3 scope, convert the pdevinfo/sdw_pdata and pdev arrays in
sdw_amd_probe_controller() from fixed-size stack arrays to heap
allocations sized by the ACP revision.

Patch 4 renames revision-specific hardware-access functions, op-table
instances, and the manager register-offset constant to the amd_acp63_*
/ACP63_* prefix.

Patch 5 removes an unused define.

Patches 6-8 introduce and wire up the hw_ops dispatch framework:
patch 6 defines struct amd_sdw_hw_ops and the inline acp_*() dispatch
helpers; patch 7 converts the irq/work handlers to dispatch per
acp_rev to their ACP6.3-family implementations; patch 8 extracts PM
callbacks into hw_ops slots, populates a static const amd_acp63_hw_ops
table, and converts all remaining direct amd_acp63_*() call sites to
use the corresponding acp_*() wrappers.

Patch 9 splits amd_manager.c: shared revision-independent functions
move to amd_manager_common.c and the ACP6.3/7.0/7.1/7.2 register-level
backend is renamed to amd_acp63_manager.c.

[PATCH V2 1/9] soundwire: amd: rename AMD_SDW_MAX_MANAGER_COUNT macro

[Vijendar Mukunda]

Rename AMD_SDW_MAX_MANAGER_COUNT to AMD_ACP63_SDW_MAX_MANAGER_COUNT and
add a comment clarifying that ACP6.3/7.0/7.1/7.2 all expose two
SoundWire manager instances. The rename makes the platform scope
explicit and matches the acp63 prefix convention used for the shared
ACP6.3-base hardware throughout the driver.

[Vijendar Mukunda]

Replace the fixed-size pdev[AMD_ACP63_SDW_MAX_MANAGER_COUNT] member of
struct sdw_amd_ctx with a dynamically allocated pointer array. The array
is sized by max_manager_count via kcalloc() in sdw_amd_probe_controller()
and freed on all error paths and in sdw_amd_cleanup().

[PATCH V2 4/9] soundwire: amd: rename hardware backend symbols to amd_acp63_*() prefix

[Vijendar Mukunda]

In preparation for the hw_ops dispatch framework, rename the
revision-specific hardware-access functions, op-table instances and
the register-offset constant in amd_manager.c / amd_manager.h to the
amd_acp63_*() / ACP63_* prefix. The amd_acp63_ prefix denotes ACP6.3
as the base revision of this shared IP block, not ACP6.3-only support.

Generic SoundWire protocol helpers (amd_sdw_xfer_msg(), amd_prop_read(),
amd_sdw_clock_stop() and related bus helpers) and the top-level
work_struct handlers (amd_sdw_irq_thread(),
amd_sdw_update_slave_status_work()) intentionally keep the amd_sdw_*()
prefix; inline comments mark them as revision-independent. All other
amd_sdw_*() and amd_*() functions in the hardware path are renamed,
including amd_acp63_sdw_process_wake_event().

[PATCH V2 5/9] soundwire: amd: remove unused AMD_SDW_MAX_FREQ_NUM define

[Vijendar Mukunda]

The AMD_SDW_MAX_FREQ_NUM macro has no users anywhere in the driver.
Remove it as a straightforward cleanup with no functional change.

[PATCH V2 6/9] soundwire: amd: introduce struct amd_sdw_hw_ops dispatch framework

[Vijendar Mukunda]

Add struct amd_sdw_hw_ops, a function-pointer dispatch table for
hardware-revision-specific SoundWire manager operations, including
register-level init/enable/disable, interrupt masking, frameshape,
wake/host-wake, command/response, ping handling, clock-stop exit,
and the PM suspend/resume paths. Add inline dispatch helpers for
each callback and a const hw_ops pointer in struct amd_sdw_manager.

[PATCH V2 7/9] soundwire: amd: dispatch irq/work handlers to per-revision functions

[Vijendar Mukunda]

Split the top-level interrupt and status-update work handlers into a
revision-specific implementation and a generic work_struct entry point.

amd_acp63_sdw_irq_thread() and amd_acp63_sdw_update_slave_status_work()
now hold the ACP6.3-family handler logic and take struct amd_sdw_manager *.

amd_sdw_irq_thread() and amd_sdw_update_slave_status_work() remain the
work_struct handlers registered with INIT_WORK(); each recovers the
manager via container_of() and switches on acp_rev, invoking the
corresponding amd_acp63_*() implementation for ACP6.3, ACP7.0, ACP7.1
and ACP7.2 and emitting dev_err() + return on an unexpected revision.

[PATCH V2 8/9] soundwire: amd: populate hw_ops and wire all call sites through acp_*() helpers

[Vijendar Mukunda]

Populate the amd_sdw_hw_ops dispatch table introduced in the previous
patch and convert every direct amd_acp63_*() call site in the driver to
use the corresponding acp_*() inline helper.

Introduce a static const struct amd_sdw_hw_ops amd_acp63_hw_ops table
that registers all amd_acp63_*() callbacks. Add amd_sdw_hw_init_ops()
which assigns the table pointer based on acp_rev, and call it from
amd_sdw_manager_probe() so hw_ops is set before any dispatch helper is
reached.

Extract the PM suspend/resume logic into amd_acp63_sdw_suspend(),
amd_acp63_sdw_suspend_runtime() and amd_acp63_sdw_resume_runtime()
hw_ops callbacks (taking struct amd_sdw_manager * instead of
struct device *). The existing amd_suspend(), amd_suspend_runtime() and
amd_resume_runtime() device-PM entry points become thin one-liners that
delegate to the corresponding acp_sdw_*() helpers.

[PATCH V2 9/9] soundwire: amd: extract shared functions into amd_manager_common.c

[Vijendar Mukunda]

Move the revision-independent amd_sdw_*() functions out of
amd_manager.c into a new amd_manager_common.c. This covers message
transfer helpers, ping and slave-status processing, DAI ops and
registration, the clock-stop sequence, PM prepare and
suspend/resume thin wrappers, and the platform_driver infrastructure.

Rename amd_manager.c to amd_acp63_manager.c now that it contains
only the amd_acp63_*() register-level functions, the amd_acp63_hw_ops
table and amd_sdw_hw_init_ops(). Update the Makefile to build
amd_manager_common.o and amd_acp63_manager.o.

Add cross-file prototypes to amd_manager.h for symbols each file
references in the other. Drop static from amd_acp63_sdw_ops,
amd_acp63_sdw_port_ops, amd_acp63_sdw_compute_params,
amd_acp63_sdw_irq_thread, amd_acp63_sdw_update_slave_status_work
and amd_sdw_hw_init_ops, which amd_manager_common.c now calls.

Move the revision-specific register-map tables (struct sdw_manager_dp_reg,
the acp63/acp70 dp_reg arrays and sdw_manager_reg_mask_array) from
amd_manager.h into amd_acp63_manager.c to avoid -Wunused-variable when
amd_manager_common.c includes the shared header.

No functional change.
