* ASoC: SOF: Intel: refactor i915_get/put functionsKai Vehmanen2020-01-271-15/+6
| | | | | | | | | | | | | | | | | The current interface to control i915 display power is misleading. The hda_codec_i915_get() and hda_codec_i915_put() names suggest a refcounting based interface. This is confusing as no refcounting is done and the underlying HDAC library interface does not support refcounts eithers. Clarify the code by replacing the functions with a single hda_codec_i915_display_power() that is aligned with snd_hdac_display_power().

* Merge tag 'asoc-fix-v5.5-rc6' into asoc-5.6Mark Brown2020-01-171-7/+12
|\ | | | | | | | | | | | | | | | | | | | | ASoC: Fixes for v5.5 This is mostly driver specific fixes, plus an error handling fix in the core. There is a rather large diffstat for the stm32 SAI driver, this is a very large but mostly mechanical update which wraps every register access in the driver to allow a fix to the locking which avoids circular locks, the active change is much smaller and more reasonably sized.
| * ASoC: SOF: Intel: fix HDA codec driver probe with multiple controllersKai Vehmanen2020-01-131-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case system has multiple HDA controllers, it can happen that same HDA codec driver is used for codecs of multiple controllers. In this case, SOF may fail to probe the HDA driver and SOF initialization fails. SOF HDA code currently relies that a call to request_module() will also run device matching logic to attach driver to the codec instance. However if driver for another HDA controller was already loaded and it already loaded the HDA codec driver, this breaks current logic in SOF. In this case the request_module() SOF does becomes a no-op and HDA Codec driver is not attached to the codec instance sitting on the HDA bus SOF is controlling. Typical scenario would be a system with both external and internal GPUs, with driver of the external GPU loaded first. Fix this by adding similar logic as is used in legacy HDA driver where an explicit device_attach() call is done after request_module(). Also add logic to propagate errors reported by device_attach() back to caller. This also works in the case where drivers are not built as modules.

* | ASoC: SOF: Intel: drop HDA codec upon probe failureKai Vehmanen2019-12-181-7/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case a HDA codec probe fails, do not raise error immediately, but instead remove the codec from bus->codec_mask and continue probe for other codecs. This allows for more robust behaviour in cases where one codec in the system is faulty. SOF driver load can still proceed with the codecs that can be probed successfully. Probe may still fail if suitable machine driver is not found, but in many cases the generic HDA machine driver can operate with a subset of codecs.

* | ASoC: SOF: intel: hda: Modify signature for hda_codec_probe_bus()Ranjani Sridharan2019-12-091-10/+6
|/ | | | | | | | | | | | | | The machine driver selection for HDA platforms will be consolidated and moved out of the SOF DSP probe callback. In preparation for that, modify the signature for hda_codec_probe_bus() to pass the hda_codec_use_common_hdmi as a variable while probing the HDA codecs.

* ASoC: SOF: Intel: add support for snd-hda-codec-hdmiKai Vehmanen2019-10-291-4/+18
| | | | | | | | | | | | | | | | | Add support to implement HDMI/DP audio by using the common snd-hda-codec-hdmi driver. Change of codec driver affects user-space as the two drivers expose different mixer controls. A new kernel module option "use_common_hdmi" is added to user-space to indicate which interface should be used. The default driver can be selected via a Kconfig option.

* ASoC: SOF: Intel: hda: Enable jack detectionRander Wang2019-07-231-2/+42
| | | | | | | | | | | | | | | | | | | | | | In commit 7d4f606c50ff ("ALSA: hda - WAKEEN feature enabling for runtime pm"), legacy HD-A driver sets hda controller in reset mode after entering runtime-suspend. And when resuming from suspend mode, it checks hda controller & codec status to detect headphone hotplug event. Now this patch does the same job in SOF runtime pm functions. And we need to check all the non-hdmi codecs for some cases like playback with HDMI or capture with DMIC connected to dsp. In these cases, only controller is active and codecs are suspended, so codecs can't send unsolicited event to controller. The jack polling operation will activate codecs and unsolicited event can work even codecs become suspended later. Tested on whiskylake with hda codecs.

* ASoC: SOF: Intel: hda: Make hdac_device device-managedRanjani Sridharan2019-07-221-4/+2
| | | | | | | | | | | | | | | | | | | | | snd_hdac_ext_bus_device_exit() has been recently modified to no longer free the hdac device. SOF allocates memory for hdac_device and hda_hda_priv with kzalloc. Make them device-managed instead so that they will be freed when the SOF driver is unloaded. Because of the above change, hda_codec is device-managed and it will be freed when the ASoC device is removed. Freeing the codec in snd_hda_codec_dev_release() leads to kernel panic while unloading and reloading the ASoC driver. So, avoid freeing the hda_codec for ASoC driver. This is done in the same patch to avoid bisect failure.
