2022-04-22ASoC: SOF: sof-pci-dev: don't use the community key on APL ChromebooksPierre-Louis Bossart1-1/+23
As suggested by MrChromebox, the SOF driver can be used with the SOF firmware binary signed with the production key. This patch adds an additional check for the ApolloLake SoC before modifying the default firmware path. Note that ApolloLake Chromebooks officially ship with the Skylake driver, so to use SOF the users have to explicitly opt-in with 'options intel-dspcfg dsp_driver=3'. There is no plan to change the default selection.

2022-04-21ASoC: SOF: amd: Use dedicated MBOX for ACP and PSP communicationAjit Kumar Pandey2-5/+25
We are currently using generic PSP Mailbox register for sending SHA complete command to PSP but observe random arbitration issue during PSP validation as MP0_C2PMSG_26_REG used by other kernel modules. Use separate mailbox registers and doorbell mechanism to send SHA_DMA complete command to PSP. This fixes such validation issues and added flexibility for sending more ACP commands to PSP in future as new mbox registers i.e MP0_C2PMSG_114_REG and MP0_C2PMSG_73_REG are dedicated by PSP for ACP communications.

2022-04-20ASoC: SOF: add INTEL_IPC4 plumbingMark Brown32-484/+671
Merge series from Pierre-Louis Bossart <[email protected]>: The INTEL_IPC4 protocol and firmware architecture will rely on different sets of firmware binary and topology files. Some platforms will only support INTEL_IPC4, some will support both INTEL_IPC4 and SOF_IPC for development, and some will stay with the existing SOF_IPC. This patchset adds new IPC definitions, and search paths for firmware and topology files, along with means to override the default IPC type and search paths for development. The firmware binary names are aligned with those used by the Intel AVS driver to avoid duplicate firmware installs, but the topology will have to differ due to driver architecture differences.
2022-04-20ASoC: Intel: avs: Topology and path managementMark Brown8-1/+3024
Merge series from Cezary Rojewski <[email protected]>: A continuation of avs-driver initial series [1]. This chapter covers path management and topology parsing part which was ealier path of the main series. The two patches that represented these two subjects in the initial series, have been split into many to allow for easier review and discussion. AVS topology is split into two major parts: dictionaries - found within ASoC topology manifest - and path templates. Dictionaries job is to reduce the total amount of memory occupied by topology elements. Rather than having every pipeline and module carry its own information, each refers to specific entry in specific dictionary by provided (from topology file) indexes. In consequence, most struct avs_tplg_xxx are made out of pointers. Path templates are similar to path descriptions found in skylake-driver and they describe how given path shall look like in runtime - number of modules and pipelines that shape it and how they are laid out. A single path template is tied either to FE or BE and thus at most to a single, user-visible endpoint when speaking of FE. Path is a software representation of its ADSP firmware equivalent. It's a logical container for pipelines which are themselves containers - this time for modules i.e. processing units. Depending on the number of audio formats supported, each path template may carry one or more descriptions of given path. During runtime, when audio format is known, description matching said format is selected and used when instantiating path on ADSP firmware side through IPCs.

Commit 3aa1e96a2b95 ("ASoC: soc-pcm: fix BE handling of PAUSE_RELEASE") did not modify the existing logic and kept the same logic for the following transition play FE1 -> BE state is START pause FE1 -> BE state is PAUSED play FE2 -> BE state is START stop FE2 -> BE state is STOP <<< !! release FE1 -> BE state is START stop FE1 -> BE state is STOP At the time it was identified by reviewers that a better solution might consist in play FE1 -> BE state is START pause FE1 -> BE state is PAUSED play FE2 -> BE state is START stop FE2 -> BE state is PAUSE <<< !! release FE1 -> BE state is START stop FE1 -> BE state is STOP This patch suggest a transition to PAUSE when all the 'active' streams are paused. This would allow for a more consistent resource management for platforms where PAUSE and STOP are handled differently. To track the special case of an FE going from PAUSE_PUSH to STOP, we add a state variable for each FE context. This 'fe_pause' boolean is set on PAUSE_PUSH and cleared on either PAUSE_RELEASE and STOP triggers.

The reference manual has this for calculating the micfil internal clock divider: MICFIL Clock rate clkdiv = ----------------- 8 * OSR * outrate (with OSR == Oversampling Rate, outrate == output sample rate) The driver first sets the MICFIL Clock rate to (outrate * 1024) and then calculates back the clkdiv value from the above calculation. Simplify this by using a fixed clkdiv value of 8 and set the MICFIL Clock rate to (outrate * clkdiv * OSR * 8). While at it drop disabling the clock before setting its rate. The MICFIL module is disabled when the rate is changed and it is also resetted before it is started again, so I doubt it's necessary to disable the clock.

struct fsl_micfil has unused fields, remove them. Signed-off-by: Sascha Hauer <[email protected]> Acked-by: Shengjiu Wang <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Mark Brown <[email protected]>
2022-04-19ASoC: fsl_micfil: drop error messages from failed register accessesSascha Hauer1-40/+13
Failed register accesses are really not expected in memory mapped registers. When it fails then the register access itself is likely not the reason, so no need to have extra error messages for each regmap access. Just drop the error messages. This also fixes some places where a return value is concatenated using 'ret |=' and then returned as error value.

Instead regmap_update_bits() use the simpler variants regmap_[set|clear]_bits() where appropriate. Signed-off-by: Sascha Hauer <[email protected]> Acked-by: Shengjiu Wang <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Mark Brown <[email protected]>
2022-04-19ASoC: fsl_micfil: use GENMASK to define register bit fieldsSascha Hauer2-141/+58
Use GENMASK along with FIELD_PREP and FIELD_GET to access bitfields in registers to straighten register access and to drop a lot of defines.

2022-04-19ASoC: fsl_micfil: do not define SHIFT/MASK for single bitsSascha Hauer2-103/+40
No need to have defines for the mask of single bits. Also shift is unused. Drop all these unnecessary defines. Signed-off-by: Sascha Hauer <[email protected]> Acked-by: Shengjiu Wang <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Mark Brown <[email protected]>
2022-04-19ASoC: fsl_micfil: drop fsl_micfil_set_mclk_rate()Sascha Hauer1-20/+0
All that the .set_sysclk hook in the micfil driver does is to pass the sysclk frequency to fsl_micfil_set_mclk_rate(). This function expects the sample rate as argument though, not any kind of sysclk frequency. The resulting rate setting of the clock is overwritten in hw_params anyway, so drop this altogether.
