Each purge request is sent by driver after master core is powered up and unresetted but before it is unstalled. On unstall, ROM begins processing the request and initializing environment for FW load. Host should await ROM's ack before moving forward. Without doing so, ROM init poll may start too early and false timeouts can occur.

Due to unconditional initial timeouts, firmware may fail to load during its initialization. This issue cannot be resolved on driver side as it is caused by external sources such as CSME but has to be accounted for nonetheless.

With _reset_link removed from the probe sequence, codec_mask at the time skl_find_hda_machine() is invoked will always be 0, so hda machine will never be chosen. Rather than reorganizing boot flow, be permissive about invalid mask. codec_mask will be set to proper value during probe_work - before skl_codec_create() ever gets called.

Skylake driver does the controller init operation twice: - first during probe (only to stop it just before scheduling probe_work) - and during said probe_work where the actual correct sequence is executed To properly complete boot sequence when iDisp codec is present, bus initialization has to be called only after _i915_init() finishes. With additional _reset_list preceding _i915_init(), iDisp codec never gets the chance to enumerate on the link. Remove the superfluous initialization to address the issue.

v5.4 changes in soc-core tightened the checks on soc_dapm_add_routes, which results in the ASoC card probe failing.

slimbus addresses are 16 bit wide, masking page numbers to wcd register at offset of 12 will limit the number for pages. So it becomes impossible to write to page 0x10 registers. Remove masking 0x800 (slimbus address range) from register address and making use of window parameters in regmap config should fix it and also will represent the registers exactly inline with Datasheet. Remove this unnessary masking and make the registers be inline with datasheet.

Olivier Moysan authored
The commit e894efef ("ASoC: core: add support to card rebind") allows to rebind the sound card after a rebind of one of its component. With this commit, the sound card is actually rebound, but may be no more functional. The following problems have been seen with STM32 SAI driver. 1) DMA channel is not requested: With the sound card rebind the simplified call sequence is: stm32_sai_sub_probe snd_soc_register_component snd_soc_try_rebind_card snd_soc_instantiate_card devm_snd_dmaengine_pcm_register The problem occurs because the pcm must be registered, before snd_soc_instantiate_card() is called. Modify SAI driver, to change the call sequence as follows: stm32_sai_sub_probe devm_snd_dmaengine_pcm_register snd_soc_register_component snd_soc_try_rebind_card 2) DMA channel is not released: dma_release_channel() is not called when devm_dmaengine_pcm_release() is executed. This occurs because SND_DMAENGINE_PCM_DRV_NAME component, has already been released through devm_component_release(). devm_dmaengine_pcm_release() should be called before devm_component_release() to avoid this problem. Call snd_dmaengine_pcm_unregister() and snd_soc_unregister_component() explicitly from SAI driver, to have the right sequence.

commit c2caa4da ("ASoC: Fix widget powerdown on shutdown") added a set of the power state during snd_soc_dapm_shutdown to ensure the widgets powered off. However, when commit 39eb5fd1 ("ASoC: dapm: Delay w->power update until the changes are written") added the new_power member of the widget structure, to differentiate between the current power state and the target power state, it did not update the shutdown to use the new_power member. As new_power has not updated it will be left in the state set by the last DAPM sequence, ie. 1 for active widgets. So as the DAPM sequence for the shutdown proceeds it will turn the widgets on (despite them already being on) rather than turning them off.

To be compliant with i915 display driver requirements, i915 power-up must be done before any HDA communication takes place, including parsing the bus capabilities. Otherwise the initial codec probe may fail. Move i915 initialization earlier in the SOF HDA sequence. This sequence is now aligned with the snd-hda-intel driver where the display_power() call is before snd_hdac_bus_parse_capabilities() and rest of the capability parsing. Also remove unnecessary ifdef around hda_codec_i915_init(). There's a dummy implementation provided if CONFIG_SND_SOC_SOF_HDA is not enabled.

When HDA controller is resumed from suspend, i915 HDMI/DP codec requires that following order of actions is kept: - i915 display power up and configuration of link params - hda link reset and setup Current SOF HDA code delegates display codec power control to the codec driver. This works most of the time, but in runtime PM sequences, the above constraint may be violated. On platforms where BIOS values for HDA link parameters do not match hardware reset defaults, this may lead to errors in HDA verb transactions after resume. Fix the issue by explicitly powering the display codec in the HDA controller resume/suspend calls, thus ensuring correct ordering. Special handling is needed for the D0i3 flow, where display power must be turned off even though DSP is left powered. Now that we have more invocations of the display power helper functions, the conditional checks surrounding each call have been moved inside hda_codec_i915_display_power(). The two special cases of display powering at initial probe are handled separately. The intent is to avoid powering the display whenever no display codecs are used. Note that early powering of display was removed in commit 687ae9e2 ("ASoC: intel: skl: Fix display power regression"). This change was also copied to the SOF driver. No failures have resulted as hardware default values for link parameters have worked out of the box. However with recent i915 driver changes like done in commit 87c16945 ("drm/i915: save AUD_FREQ_CNTRL state at audio domain suspend"), this does not hold anymore and errors are hit.
