Pull firewire updates from Takashi Sakamoto:
 "In the FireWire subsystem, tasklets have been used as the bottom half
  of 1394 OHCi hardIRQ. In recent kernel updates, BH workqueues have
  become available, and some developers have proposed replacing the
  tasklet with a BH workqueue.

  As a first step towards dropping tasklet use, the 1394 OHCI
  isochronous context can use regular workqueues. In this context, the
  batch of packets is processed in the specific queue, thus the timing
  jitter caused by task scheduling is not so critical.

  Additionally, DMA transmission can be scheduled per-packet basis,
  therefore the context can be sleep between the operation of
  transmissions. Furthermore, in-kernel protocol implementation involves
  some CPU-bound tasks, which can sometimes consumes CPU time so long.
  These characteristics suggest that normal workqueues are suitable,
  through BH workqueues are not.

  The replacement with a workqueue allows unit drivers to process the
  content of packets in non-atomic context. It brings some reliefs to
  some drivers in sound subsystem that spin-lock is not mandatory
  anymore during isochronous packet processing.

  Summary:

   - Replace tasklet with workqueue for isochronous context

   - Replace IDR with XArray

   - Utilize guard macro where possible

   - Print deprecation warning when enabling debug parameter of
     firewire-ohci module

   - Switch to nonatomic PCM operation"

Pull thermal control updates from Rafael Wysocki:
 "These mostly continue to rework the thermal core and the thermal zone
  driver interface to make the code more straightforward and reduce
  bloat

  The most significant piece of this work is a change of the code
  related to binding cooling devices to thermal zones which, among other
  things, replaces two previously existing thermal zone operations with
  one allowing driver implementations to be much simpler

  There is also a new thermal core testing module allowing mock thermal
  zones to be created and controlled via debugfs in order to exercise
  the thermal core functionality. It is expected to be used for
  implementing thermal core self tests in the future

  Apart from the above, there are assorted thermal driver updates

  Specifics:

   - Update some thermal drivers to eliminate thermal_zone_get_trip()
     calls from them and get rid of that function (Rafael Wysocki)

   - Update the thermal sysfs code to store trip point attributes in
     trip descriptors and get to trip points via attribute pointers
     (Rafael Wysocki)

   - Move the computation of the low and high boundaries for
     thermal_zone_set_trips() to __thermal_zone_device_update() (Daniel
     Lezcano)

   - Introduce a debugfs-based facility for thermal core testing (Rafael
     Wysocki)

   - Replace the thermal zone .bind() and .unbind() callbacks for
     binding cooling devices to thermal zones with one .should_bind()
     callback used for deciding whether or not a given cooling devices
     should be bound to a given trip point in a given thermal zone
     (Rafael Wysocki)

   - Eliminate code that has no more users after the other changes, drop
     some redundant checks from the thermal core and clean it up (Rafael
     Wysocki)

   - Fix rounding of delay jiffies in the thermal core (Rafael Wysocki)

   - Refuse to accept trip point temperature or hysteresis that would
     lead to an invalid threshold value when setting them via sysfs
     (Rafael Wysocki)

   - Adjust states of all uninitialized instances in the .manage()
     callback of the Bang-bang thermal governor (Rafael Wysocki)

   - Drop a couple of redundant checks along with the code depending on
     them from the thermal core (Rafael Wysocki)

   - Rearrange the thermal core to avoid redundant checks and simplify
     control flow in a couple of code paths (Rafael Wysocki)

   - Add power domain DT bindings for new Amlogic SoCs (Georges Stark)

   - Switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr() in the ST
     driver and add a Kconfig dependency on THERMAL_OF subsystem for the
     STi driver (Raphael Gallais-Pou)

   - Simplify the error code path in the probe functions in the brcmstb
     driver with the helo of dev_err_probe() (Yan Zhen)

   - Make imx_sc_thermal use dev_err_probe() (Alexander Stein)

   - Remove trailing space after \n newline in the Renesas driver (Colin
     Ian King)

   - Add DT binding compatible string for the SA8255p to the tsens
     thermal driver (Nikunj Kela)

   - Use the devm_clk_get_enabled() helpers to simplify the init routine
     in the sprd thermal driver (Huan Yang)

   - Remove __maybe_unused notations for the functions by using the new
     RUNTIME_PM_OPS() and SYSTEM_SLEEP_PM_OPS() macros on the IMx and
     Qoriq drivers (Fabio Estevam)

   - Remove unused declarations from the ti-soc-thermal driver's header
     file as the functions in question were removed previously (Zhang
     Zekun)"

<title>firewire: core: expose kernel API to schedule work item to process isochronous context</title>

<link rel='alternate' type='text/html' href='https://git.kobert.dev/pm24.git/commit/?id=446216bd8e5d4a3ffc9738f6adffc98fbfdcc582'/>
<id>urn:sha1:446216bd8e5d4a3ffc9738f6adffc98fbfdcc582</id>
<content type='text'>
In packet-per-buffer mode for isochronous context of 1394 OHCI, software
can schedule hardIRQ to the buffer in which the content of isochronous
packet is processed. The actual behaviour is different between isochronous
receive (IR) and transmit (IT) contexts in respect to isochronous cycle in
which the hardIRQ occurs.

In IR context, the hardIRQ occurs when the buffer is filled actually by
the content of received packet. If there are any isochronous cycles in
which the packet transmission is skipped, it is postponed to generate
the hardIRQ in respect to the isochronous cycle. In IT context, software
can schedule the content of packet every isochronous cycle including
skipping, therefore the hardIRQ occurs in the isochronous cycle to which
the software scheduled.

ALSA firewire stack uses the packet-per-buffer mode for both IR/IT
contexts. To process time stamp per packet (or per sample in some cases)
steadily for media clock recovery against unexpected transmission skips,
it uses an IT context to operate all of isochronous contexts by calls of
fw_iso_context_flush_completions() in the bottom-half of hardIRQ for the
IT context.

Although it looks well to handle all of isochronous contexts in a single
bottom-half context, it relatively takes longer time. In the future code
integration (not yet), it is possible to apply parallelism method to
process these context. In the case, it is useful to allow unit drivers to
schedule work items to process these isochronous contexts.

As a preparation, this commit exposes
fw_iso_context_schedule_flush_completions() as a kernel API available by
unit drivers. It is renamed from fw_iso_context_queue_work() since it is
a counter part of fw_iso_context_flush_completions().
