Address review findings for the recently merged AudioReach TDM backend
support.
The first patch fixes a typo in the newly added QAIF clock ID names by
renaming the LAPSS-prefixed identifiers to LPASS and updating all
corresponding in-tree users.
The remaining patches address issues identified in the AudioReach TDM
configuration and machine-driver paths:
- Zero-initialize AudioReach module configuration structures so
unspecified slot parameters correctly fall back to topology defaults.
- Distinguish between missing TDM configuration and malformed TDM slot
properties by using separate return codes, preventing valid DT
configuration errors from being silently ignored.
- Fix sc8280xp TDM hw_params error handling by properly distinguishing
optional and invalid TDM slot configurations and propagating errors
accordingly.
All issues were reported by Sashiko.

q6apm_dai_prepare() and q6apm_dai_compr_set_params() build an
AudioReach module config on the stack and populate only the fields
needed for the stream type.
Audio IF media-format setup treats zero slot_mask, nslots_per_frame and
slot_width as a request to use the topology defaults. Leave those fields
uninitialized and random stack data can override the topology values sent
to the DSP.
Initialize the whole config structure so omitted fields reliably retain
their zero/default meaning.

q6apm_graph_start() increments start_count even when APM_CMD_GRAPH_START
fails, leaving the graph counted as running while the DSP never started
it. A later start - a retried prepare, or a resume after a failed start -
then finds a non-zero count, skips the command and returns success with
no data flowing.
Count the graph only once the DSP has accepted the start. The count then
stays at zero for a graph that never started, so also stop decrementing
below zero in q6apm_graph_stop(): the compressed free path stops
unconditionally, and a negative count would make the next start skip the
command in the same way.

Add the Audio IF module IDs, the required topology tokens, and a dedicated
topology loader that stores the parsed interface configuration in the
AudioReach module state. Also add the Audio IF media-format path that
sends the interface configuration, hardware endpoint media format, and
frame-duration parameters for Audio IF modules.

The new UAPI tokens (AR_TKN_U16_MODULE_SYNC_SRC=262 through
AR_TKN_U8_MODULE_INV_EXT_BIT_CLK=276) are added, together with the value

The Qualcom SM8650 based Ayaneo Pocket S2 gaming device has a set
of 2 WSA speakers connected on the WSA2 lines.
But the Audioreach DSP only handles WSA2 in pair with the WSA
interface by using the upper bits of the active_channels_mask
for WSA2 and the lower bits for WSA:
/-------------------------------------------------\
| Bits | 3 | 2 | 1 | 0 |
|-------------------------------------------------|
| Line | WSA2 Ch2 | WSA2 Ch1 | WSA Ch2 | WSA Ch1 |
\-------------------------------------------------/
Setting only the WSA2 upper bits is perfectly valid and
functional but the current Audioreach code builds the bitmask
from the channels count with:
active_channels_mask = (1 << num_channels) - 1;
In order to enable the WSA2 bits the channel count should be 4,
but the lower WSA bits are then also enabled and the DSP errors
out when trying to play on the disabled WSA interface.
A solution would've been to add a fake WSA2 topology element which
would be translated into the top bits only, but it's not clean and
add some special exceptions in the generic Audioreach code.
The solution suggested by Srinivas is to use the channel mapping to
set this bitmask.
This works but makes all the other calls using the channel mapping fail
because the DSP requires the channel_mapping table to start from index 0
and using num_channel length in order to apply the mapping on the
active_channels_mask bits in order.
So we need to skip the empty channel mapping entries in all other
users of the channel_map to build valid channel_mapping tables.
This should not break any other usecases since the default channel
mapping always start from index 0, and will add flexibilty to allow
some special non linear mapping for other interfaces as well.

When q6apm_free_fragments() is called it frees rx_data.buf/tx_data.buf
and sets them to NULL under graph->lock. A late DSP buffer-done response
can race with this: graph_callback() passes the !graph->ar_graph guard
(not yet NULL), acquires the lock, but then dereferences a now-NULL buf
pointer to read buf[token].phys, crashing at virtual address 0x10.
Add a NULL check for buf inside the mutex-protected section in both the
write-done (DATA_CMD_RSP_WR_SH_MEM_EP_DATA_BUFFER_DONE_V2) and
read-done (DATA_CMD_RSP_RD_SH_MEM_EP_DATA_BUFFER_V2) handlers and bail
out cleanly if buffers have already been freed.
This problem is only shown up recently while apr bus was updated to
process the commands per service rather from single global queue.

The q6asm-dai stream state is used by prepare() to decide whether an
existing stream setup needs to be closed before opening/configuring a new
one. Updating the state from trigger or asynchronous DSP callbacks can make
that state stale or incorrect relative to the actual setup lifetime.
In particular, setting Q6ASM_STREAM_STOPPED on STOP or EOS completion can
make prepare() believe there is no active setup to close, which can result
in opening/configuring the same stream more than once.
Keep stream state updates tied to prepare(), where the stream is actually
closed and reopened, and stop changing it from trigger and EOS callbacks.

Some Old DSP firmware versions use 32-bit address arithmetic and size for
validating the PCM buffer address range. If a buffer is allocated near
the top of the 32-bit address space, arithmetic calculations involving
the end address can overflow and fail checks.
Work around this by increasing the preallocated PCM buffer size by one
page. The DSP is still passed the usable buffer size, excluding the extra
page, which prevents the firmware from seeing an end address that crosses
the 32-bit boundary.
This was not hit before because PCM buffer allocation and DSP-side
mapping happened at different points, and the size mapped on the DSP was
usually nperiods * period_size. Therefore the mapped size was unlikely to
match the full preallocated buffer size exactly, although the issue was
still possible. With early buffer mapping on the DSP, the full
preallocated buffer is mapped during PCM creation, making the failure
reproducible at boot.

Merge tag 'rpmsg-v7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux
Pull rpmsg updates from Bjorn Andersson:
"Mark 'data' argument in rpmsg_send() const, and perculate to related
drivers. Replace deprecated class_destroy() with class_unregister()"
* tag 'rpmsg-v7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux:
media: platform: mtk-mdp3: Constify buffer passed to mdp_vpu_sendmsg()
ASoC: qcom: Constify GPR packet being send over GPR interface
rpmsg: Constify buffer passed to send API
remoteproc: mtk_scp: Constify buffer passed to scp_send_ipi()
remoteproc: mtk_scp_ipi: Constify buffer passed to scp_ipi_send()
drivers: rpmsg: class_destroy() is deprecated
gpr_send_pkt() and pkt_router_send_svc_pkt() only send the GPR packet
they receive, without any need to actually modify it, so mark the
pointer to GPR packet as pointer to const for code safety and code
self-documentation. Several users of this interface can follow up and
also operate on pointer to const.

Buffers are allocated on pcm_new and mapped in the dsp on every
prepare call, which is inefficient and unnecessary.
Add new functions q6apm_[un]map_memory_fixed_region to map it on
to dsp only once after allocation.

Remove searching for Shared Memory module instance id on every
read/write call, this is un-necessary if we can cache the shared
memory module instance id per PCM graph.
Add new member to graph struct to store shared memory module
instance id to avoid searching for this in hot path.

Start the graph at trigger callback. Staring the graph at prepare does
not make sense as there is no data transfer at this point.
Moving this to trigger will also help cope situation where pipewire
is not happy if display port is not connected during start.

lpass ports numbers have been added but the afe/apm driver never got
updated with new max port value that it uses to store dai specific data.
There are more than one places these values are cached and always become
out of sync.
This will result in array out of bounds and weird driver behaviour.
To catch such issues, first add a single place where we can define max
port and second add a check in common parsing code which can error
out before corrupting the memory with out of bounds array access.
This should help both avoid and catch these type of mistakes in future.

Reset queue pointer on SNDRV_PCM_TRIGGER_STOP event to be inline
with resetting appl_ptr. Without this we will end up with a queue_ptr
out of sync and driver could try to send data that is not ready yet.
Fix this by resetting the queue_ptr.

This will result in a memory leaks, fix this by adding a check before

looks like q6apm driver does not remove the child driver q6apm-dai and
q6apm-bedais when the this driver is removed.
Fix this by depopulating them in remove callback.
With this change when the dsp is shutdown all the devices associated with
q6apm will now be removed.

We have been used pcm_new()/pcm_free(), but switched to
pcm_construct()/pcm_destruct() to use extra parameters [1].
pcm_new()/free() had been removed [2], but each drivers are still
using such function naming. Let's name back to pcm_new()/pcm_free()
again.
