      ASoC: hdac_hdmi: remove cancel_work_sync in runtime suspend · cec6e41c
      Brent Lu authored 
      A deadlock is identified when there are three contexts running at the
same time:
- a HDMI jack work which is calling snd_soc_dapm_sync().
- user space is calling snd_pcm_release() to close pcm device.
- pm is calling runtime suspend function of HDMI codec driver.

By removing the clear_dapm_works() invocation in the
hdac_hdmi_runtime_suspend() function, the snd_pcm_release() could
always returns from dapm_power_widgets() function call without
blocking the hdac_hdmi_jack_dapm_work() work thread or being blocked
by the hdac_hdmi_runtime_suspend() function. The purpose of the jack
work is to enable/disable the dapm jack pin so it's not necessary to
cancel the work in runtime suspend function which is usually called
when pcm device is closed.

      Merge series "ASoC: Intel: Catpt - Lynx and Wildcat point" from Cezary... · 1a4c450e

      Merge series "ASoC: Intel: Catpt - Lynx and Wildcat point" from Cezary Rojewski <cezary.rojewski@intel.com>:

Implement support for Lynxpoint and Wildcat Point AudioDSP. Catpt
solution deprecates existing sound/soc/intel/haswell which is removed in
the following series.

Due to high range of errors and desynchronization from recommendations
set by Windows solution, re-write came as a lower-cost solution compared
to refactoring /haswell/ with several series of patches.

Series is dependent on linux-spi change:
spi: pxa2xx: Add SSC2 and SSPSP2 SSP registers
https://www.spinics.net/lists/linux-spi/msg23885.html
which has been already merged and is now part of linux-spi tree.

Bulk of series content is device driver core code - everything up to
patch 7/14 - with fs entries and trace macros introduced right after.
While each core patch is shaped in such a way that no unavailable
members are ever called, until patch 14/14 is applied, no code
compilation can occur as no Makefile is present. Once said patch is
added, Makefile and Kconfig are implemented and driver module compiles
as expected.

Special thanks go to Marcin Barlik and Piotr Papierkowski for sharing
their LPT/WPT AudioDSP architecture expertise as well as helping
backtrack its historical background.
My thanks go to Amadeusz Slawinski for reviews and improvements proposed
on and off the internal list. Most of internal diff below is his
contribution.
Krzysztof Hejmowski helped me setup my own Xtensa environment and
recompile LPT/WPT FW binary sources what sped up the development greatly.

This would not have been possible without help from these champions,
especially considering how quickly the catpt was written: 2 weeks
features, 3 weeks optimizations. Thank you.

Userspace-exposed members are compatible with what is exposed by
deprecated solution as well as FW binary being re-used thus no harm is
done. The only visible differences are: the newly added 'Loopback Mute'
kcontrol and volume support extending to quad from stereo.

On top of fixing erros and design flows, catpt also adds module reload,
dynamic SRAM memory allocation during PCM runtime and exposes missing
userspace API: 'Loopback Mute' kcontrol, quad volume controls and sysfs
fw-version entries. Event tracing is provided to ease solution
debugging.

Following are not included in this update and are scheduled as later
addition:
- fw logging
- module (library) support

Note: LPT power up/down sequences might get aligned with WPT once enough
testing is done as capabilities are shared for both DSPs.
Note #2: Both LPT and WPT power up/down sequences may get optimized in
future updates as thanks to help from the Windows team, most of nuances
behind why/what/when in regard to hw registers have been backtracked and
reviewed again.

Link to developer's deep dive message:
https://www.spinics.net/lists/alsa-devel/msg113563.html

Changes in v10:
- reverted DUAL_MONO case relocation from v9
- indented all constants of enum catpt_module_id to the same column
- new newline appended for return path of catpt_dsp_do_send_msg()

Changes in v9:
https://www.spinics.net/lists/alsa-devel/msg116305.html
- fixed newlines in sysfs as requested by Andy, left tags as no other
  changes done
- removed volume_map and replaced by simple formulas for volume kcontrol
  calculations
- removed redundant parentheses in catpt_get_channel_map() and
  relocated DUAL_MONO case
- runtime suspend no longer called during module unload
- removed redundant size checks for catpt_dsp_send_tx() and
  catpt_dsp_copy_rx()

Changes in v8:
https://www.spinics.net/lists/alsa-devel/msg116168.html
- updated catpt_arrange_page_table() with GENMASK and U32_MAX usage
- made use of PFN_DOWN() replacing explicit right shitfs by PAGE_SIZE
- made fw hash dumping in catpt_coredump() more readable and removed
  hardcodes
- catpt_coredump() dumps fw hash now only if said segment has been found
  within fw_info
- shortened _MSECS suffixes to _MS
- IPC structs no longer contain enum members
- simplified definition of catpt_set_dspvol()

Changes in v7:
https://www.spinics.net/lists/alsa-devel/msg116019.html
- fixed licence header for fs.c
- renamed fs.c to sysfs.c to better match its purpose
- added documentation within Documentation/ABI/testing for entries
  exposed by catpt
- bin_attribute fw_build replaced by attribute fw_info:
  fw_info contains full FW information and after successful handshake,
  it's always available (stored in driver data) so no need to invoke
  GET_FW_VERSION IPC again, just dump the stored information
- rather than manually creating and removing sysfs files, now makes use
  of dev_groups member of struct device_driver
- patch: 10/14 'ASoC: Intel: Select catpt and deprecate haswell' has
  been moved to the back of the list: enable catpt after machine boards
  have been prepared for it first
- improved readability of several goto labels

Changes in v6:
https://www.spinics.net/lists/alsa-devel/msg115765.html
- reordered and reorganized code for patches 1/13 - 8/13 of v5, so each
  patches makes use of no member or function which is unavailable to it.
  Series size increased from 13 to 14 patches: addition of base members
  e.g.: registers has been split from addition of device.c file which
  describes acpi device behavior

Changes in v5:
https://www.spinics.net/lists/alsa-devel/msg115621.html
Basically everything below is result of Andy's review. Thank you Andy
for taking time into this detailed review

- catpt now makes use of common linux/pxa2xx_ssp.h header file, removing
  redundant SSP register declarations in the process. As stated in the
  opening, this is dependent upon linux-spi change:
  spi: pxa2xx: Add SSC2 and SSPSP2 SSP registers

- updated Kconfig by removing DMADEVICES and adding COMPILE_TEST
  as optional depends-on
- updated all register macros definitions to be more safe against common
  arithmetics when specifying macro's parameters
- removed CONFIG_PM and CONFIG_PM_SLEEP usage in favor of __maybe_unused
- all 'if (ret < 0)' converted to simple 'if (ret)' whenever possible
- fixed erroneous check for platform_device_register_data within
  catpt_register_board()
- _SLAVE/_MASTER replaced with more inclusive _CONSUMER/_PROVIDER for
  enum catpt_ssp_mode
- catpt_acpi_probe() is now making use of high-level wrappers for
  ioremapping and resource assignment, reducing function's code size
- due to improved catpt_acpi_probe() behavior, catpt_acpi_remove() needs
  not to cast dma_free_coherent() any longer
- DMA source and destrination maxburst now of value 16, see:
https://www.spinics.net/lists/alsa-devel/msg114394.html

- simplified catpt_dsp_update_lpclock() as list_for_each_entry() is
  empty-safe by default
- dropped '_SSP_' from all names of all CATPT_SSP_SSXXX_DEFAULT macros
- catpt_updatel_pci now makes use of linux/pci.h and uapi/linux/pci.h
  constants such as: PCI_PM_CTRL_STATE_MASK and PCI_D3hot

Changes in v4:
https://www.spinics.net/lists/alsa-devel/msg113762.html
- fixed compilation with i386 kconfig (conflicting names)
- streamlined naming for SHIM and PCI registers to match SSP ones
  (SHIM_REG -> SHIM)
- catpt_component_probe removed and kcontrols again initializzed
  statically via snd_kcontrol_new array: this is to remove
  kctl->id.device shenanigans
- renamed catpt_set_ctlvol to catpt_set_dspvol - function name wasn't
  matching its purpose

Changes in v3:
- fixed IRAM mask usage in lpt_dsp_power_up (dsp.c)
- updated dbg message formatting in catpt_restore_fwimage as suggested
  by Andy
- fixed alignment for struct catpt_ssp_device_format
- catpt_set_ctlvol now verifies all-equal scenario based on all
  channels rather than just first two as requested by Amadeo
- fixed SPDX for registers.h

Changes in v2:
https://www.spinics.net/lists/alsa-devel/msg113660.html
- fixed SPDX formatting for all header files as well as pcm.c
- fixed size provided to memcpy() in fw_build_read() as reported by Mark
- renamed struct catpt_pdata to struct catpt_spec (cosmetic)
- fixed erroneous path in catpt_load_block: region is properly released
- trace.h events for updating registers have been removed and usages
  replaced by dev_dbg (SRAMPGE/ LPCS)

- as requested by Andy, struct resource has replaced struct catpt_mbank
  and struct catpt_mregion. This change cascaded into:

  - catpt_mbank_size and catpt_mregion_size replaced by resource_size
  - catpt_mregion_intersects replaced by resource_overlaps
  - all catpt_mbank_ and catpt_mregion_ handlers found in loader.c
    (_request, _reserve, _release, _extract, _split, _join) have been
    removed
  - __request_region and __release_region have been enlisted in their
    place
  - catpt_mregion_intersecting renamed to catpt_resource_overlapping
  - catpt_request_region helper has been provided to deal with -size
    based requests
      o haven't found direct replacements in resource.c/ ioport.h for
      both functions

  - catpt_mbank_create and catpt_mbank_remove renamed to catpt_sram_init
    and catpt_sram_free respectively
  - catpt_sram_init now returns void instead of int and has been
    converted to simple initialized. This change ultimately cascaded
    into:
      o both SRAM banks initialization being moved to catpt_dev_init
        from catpt_acpi_probe (device.c)
      o catpt_dev::spec is now initialized first, with catpt_dev_init
        following it soon after
      o catpt_acpi_probe erroneous path has been simplified as SRAM
        banks no longer need to be freed

  - catpt_sram_free now frees all resources via child -> sibling
    enumeration rather than region_list iteration
  - catpt_dsp_update_srampge and catpt_dsp_set_srampge now accept new
    argument: unsigned long mask. Caused by removal of catpt_mbank -
    mask is taken directly from catpt_dev::spec::d/iram_mask
  - trace.h events for catpt_mbank and catpt_mregion have been removed

Diff against last drop on internal list:
https://www.spinics.net/lists/alsa-devel/msg113549.html
- replaced spinlock with mutex for mregion allocation and release to
  address sleeping in atomic context warnings
- fixed coredump fw_hash dumping
- kcontrol values are now always stored regardless of stream of interest
  is running or not
- kcontrol values are now applied after stream is prepared instead of
  ignoring what has been set by user initially
- catpt_pdata instances have been renamed from hsw_ and bdw_ to lpt_ and
  wpt_ respectively
- reordered Makefile .o(s) (cosmetic)

After adding "depends on COMMON_CLK" for SND_SOC_QDSP6, the Kconfig
