      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)

      ASoC: qcom: fix SDM845 & QDSP6 dependencies more · 2bc8831b
      Randy Dunlap authored
      Fix a build error and Kconfig warning in sound/soc/qcom/.
      
      ld: sound/soc/qcom/qdsp6/q6afe-clocks.o: in function `q6afe_clock_dev_probe':
      q6afe-clocks.c:(.text+0x182): undefined reference to `devm_clk_hw_register'
      ld: q6afe-clocks.c:(.text+0x19d): undefined reference to `of_clk_add_hw_provider'
      
      After adding "depends on COMMON_CLK" for SND_SOC_QDSP6, the Kconfig

      ASoC: Intel: Select catpt and deprecate haswell · 6cbfa11d
      Cezary Rojewski authored
      Prevent sound/soc/intel/haswell code compile and select catpt instead as
      a recommended solution. Userspace-exposed members are compatible with
      what is exposed by deprecated solution thus no harm is done. The only
      visible difference is the newly added 'Loopback Mute' kcontrol.

      ASoC: Intel: catpt: PCM operations · a126750f
      Cezary Rojewski authored
      DSP designed for Lynxpoint and Wildcat Point offers no dynamic topology
      i.e. all pipelines are already defined within firmware and host is
      relegated to allocing stream for predefined pins. This is represented by
      'catpt_topology' member.
      
      Implementation covers all available pin types:
      - system playback and capture
      - two offload streams
      - loopback (reference)
      - bluetooth playback and capture
      
      PCM DAI operations differentiate between those pins as some (mainly
      offload) are to be handled differently - DSP expects wp updates on each
      notify_position notification.
      
      System playback has no volume control capability as it is routed to
      mixer stream directly. Other primary streams - capture and two offloads
      - offer individual volume controls.
      
      Compared to sound/soc/intel/haswell this configures SSP device format
      automatically on pcm creation.

      ASoC: Intel: catpt: Firmware loading and context restore · a9aa6fb3
      Cezary Rojewski authored
      For Lynxpoint and Wildcat Point solution, is it host's responsibility to
      allocate SRAM regions and ensure those already taken are not overwritten
      with other data until released. Blocks are transferred to SRAM - either
      IRAM or DRAM - via DW DMA controller. Once basefw is booted, ownership
      of DMA transfer is lost in favour of DSP.
      
      Hosts reponsibilities don't end on initial block allocation and binary
      transfer. During Dx transitions host must store FW runtime context from
      DRAM before putting AudioDSP subsystem into lower power state. Said
      context gets flashed after D0 entry to bring DSP right where it was just
      before suspending.
      
      Load and restore procedures are finalized with SRAM power gating and
      adequate clock level selection. This power gates unused EBBs and clock
      speed effectively reducing power consumption.
