Currently we send a BRA message with a start address with continuous
registers in a BPT stream. However, a codec may need to write different
register sections shortly. Introduce a register section in struct
sdw_btp_msg which contain register start address, length, and buffer.
This commit uses only 1 section for each BPT message. And we need to add
up all BPT section length and check if it reach maximum BPT bytes.
No function changes.

Currently, we calculate the required bandwidth after the PDI buffer size
is calculated. However as we need to add some fake frame to align the
data block size, the final PDI size and the frame number will change.
Besides, we need the required bandwidth to decide the DMA channel number
and the channel number will be used to calculate the data block size.
Therefore, we calculate the required bandwidth and export a helper for
the caller to get the required bandwidth.

Starting with commit f99508074e ("PM: domains: Detach on
device_unbind_cleanup()"), there is no longer a need to call
dev_pm_domain_detach() in the bus remove function. The
device_unbind_cleanup() function now handles this to avoid
invoking devres cleanup handlers while the PM domain is
powered off, which could otherwise lead to failures as
described in the above-mentioned commit.
Drop the explicit dev_pm_domain_detach() call and rely instead
on the flags passed to dev_pm_domain_attach() to power off the
domain.

Dan has also reported following issues with the original patch
https://lore.kernel.org/all/33fe8fe7-719a-405a-9ed2-d9f816ce1d57@sabinyo.mountain/
Bug #1:
The zeroeth element of ctrl->pconfig[] is supposed to be unused. We
start counting at 1. However this code sets ctrl->pconfig[0].ch_mask = 128.
Bug #2:
There are SLIM_MAX_TX_PORTS (16) elements in tx_ch[] array but only
QCOM_SDW_MAX_PORTS + 1 (15) in the ctrl->pconfig[] array so it corrupts
memory like Yongqin Liu pointed out.
Bug 3:
Like Jie Gan pointed out, it erases all the tx information with the rx
information.

Calling dev_pm_domain_attach()/dev_pm_domain_detach() in bus driver
probe/remove functions can affect system behavior when the drivers
attached to the bus use devres-managed resources. Since devres actions
may need to access device registers, calling dev_pm_domain_detach() too
early, i.e., before these actions complete, can cause failures on some
systems. One such example is Renesas RZ/G3S SoC-based platforms.
If the device clocks are managed via PM domains, invoking
dev_pm_domain_detach() in the bus driver's remove function removes the
device's clocks from the PM domain, preventing any subsequent
pm_runtime_resume*() calls from enabling those clocks.
The second argument of dev_pm_domain_attach() specifies whether the PM
domain should be powered on during attachment. Likewise, the second
argument of dev_pm_domain_detach() indicates whether the domain should be
powered off during detachment.
Upcoming changes address the issue described above (initially for the
platform bus only) by deferring the call to dev_pm_domain_detach() until
after devres_release_all() in device_unbind_cleanup(). The detach_power_off
field in struct dev_pm_info stores the detach power off info from the
second argument of dev_pm_domain_attach().
Because there are cases where the device's PM domain power-on/off behavior
must be conditional (e.g., in i2c_device_probe()), the patch introduces
PD_FLAG_ATTACH_POWER_ON and PD_FLAG_DETACH_POWER_OFF flags to be passed
to dev_pm_domain_attach().
Finally, dev_pm_domain_attach() and its users are updated to use the newly
introduced PD_FLAG_ATTACH_POWER_ON and PD_FLAG_DETACH_POWER_OFF macros.
This change is preparatory.

The sdw_dev_lock protects the SoundWire driver callbacks against
the probed flag, which is used to skip the callbacks if the
driver gets removed. For more information see commit bd29c00edd
("soundwire: revisit driver bind/unbind and callbacks").
However, this lock is a frequent source of mutex inversions.
Many audio operations eventually hit the hardware resulting in a
SoundWire callback, this means that typically the driver has the
locking order ALSA/ASoC locks -> sdw_dev_lock. Conversely, the IRQ
comes in directly from the SoundWire hardware, but then will often
want to access ALSA/ASoC, such as updating something in DAPM or
an ALSA control. This gives the other lock order sdw_dev_lock ->
ALSA/ASoC locks.
When the IRQ handling was initially added to SoundWire this was
through a callback mechanism. As such it required being covered by
the lock because the callbacks are part of the sdw_driver structure
and are thus present regardless of if the driver is currently
probed.
Since then a newer mechanism using the IRQ framework has been
added, which is currently covered by the same lock but this isn't
actually required. Handlers for the IRQ framework are registered in
probe and should by released during remove, thus the IRQ framework
will have already unbound the IRQ before the slave driver is
removed. Avoid the aforementioned mutex inversion by moving the
handle_nested_irq call outside of the sdw_dev_lock.

ACE3 introduced microphone privacy and along this feature it adds a new
register in vendor specific SHIM to control and status reporting.
The control of mic privacy via the SHIM register is only to enable the
interrupt generation via soundwire, but not handled by the soundwire code
as the mic privacy is not a feature of the soundwire IP.
On the other hand, printing the register value brings value for debugging,
so add a new flag to allow this conditionally.

Currently the SoundWire IRQ code uses the dev_num to create an IRQ
mapping for each slave. However, there is an issue there, the dev_num
is only allocated when the slave enumerates on the bus and enumeration
may happen before or after probe of the slave driver. In the case
enumeration happens after probe of the slave driver then the IRQ
mapping will use dev_num before it is set. This could cause multiple
slaves to use zero as their IRQ mapping.
It is very desirable to have the IRQ mapped before the slave probe
is called, so drivers can do resource allocation in probe as normal. To
solve these issues add an internal ID created for each slave when it is
probed and use that for mapping the IRQ.

Before commit bca84a7b93 ("PM: sleep: Use DPM_FLAG_SMART_SUSPEND
conditionally") the runtime PM status of the device in intel_resume()
had always been RPM_ACTIVE because setting DPM_FLAG_SMART_SUSPEND had
caused the core to call pm_runtime_set_active() for that device during
the "noirq" resume phase. For this reason, the pm_runtime_suspended()
check in intel_resume() had never triggered and the code depending on
it had never run. That had not caused any observable functional issues
to appear, so effectively the code in question had never been needed.
After commit bca84a7b93 the core does not call pm_runtime_set_active()
for all devices with DPM_FLAG_SMART_SUSPEND set any more and the code
depending on the pm_runtime_suspended() check in intel_resume() runs if
the device is runtime-suspended prior to a system-wide suspend
transition. Unfortunately, when it runs, it breaks things due to the
attempt to runtime-resume bus->dev which most likely is not ready for a
runtime resume at that point.
It also does other more-or-less questionable things. Namely, it
calls pm_runtime_idle() for a device with a nonzero runtime PM usage
counter which has no effect (all devices have nonzero runtime PM
usage counters during system-wide suspend and resume). It also calls
pm_runtime_mark_last_busy() for the device even though devices cannot
runtime-suspend during system-wide suspend and resume (because their
runtime PM usage counters are nonzero) and an analogous call is made
in the same function later. Moreover, it sets the runtime PM status
of the device to RPM_ACTIVE before activating it.
For the reasons listed above, remove that code altogether.
On top of that, add a pm_runtime_disable() call to intel_suspend() to
prevent the device from being runtime-resumed at any point after
intel_suspend() has started to manipulate it because the changes
made by that function would be undone by a runtime-suspend of the
device.
Next, once runtime PM has been disabled, the runtime PM status of the
device cannot change, so pm_runtime_status_suspended() can be used
instead of pm_runtime_suspended() in intel_suspend().
Finally, make intel_resume() call pm_runtime_set_active() at the end to
set the runtime PM status of the device to "active" because it has just
been activated and re-enable runtime PM for it after that.
Additionally, drop the setting of DPM_FLAG_SMART_SUSPEND from the
driver because it has no effect on devices handled by it.
