* ASoC: Intel: Remove SST-legacy specific constantsCezary Rojewski2020-10-061-2/+0
| | | | | | | | | | | As sound/soc/intel/haswell and /baytrail are no more, all SST-legacy specific constants and registers are redundant so remove them.

* ASoC: Intel: Remove unused DSP operationsCezary Rojewski2020-10-061-1/+0
| | | | | | | | | | | | | | sound/soc/intel/common/ declares several helper functions for /intel/ solutions. In practice, differences between these - /haswell/ and /skylake/ especially - led to many of the helpers being used only by a single solution. As /skylake/ makes no use of these and /haswell/ and /baytail/ are no more, remove the unused functions.

* ASoC: Intel: Update request-reply IPC modelCezary Rojewski2019-08-071-13/+14
| | | | | | | | | | | | | | | | | | | | | | | | struct ipc_message contains fields: header, tx_data and tx_size which represent TX i.e. request while RX is represented by rx_data and rx_size with reply's header equivalent missing. Reply header may contain some vital information including, but not limited to, received payload size. Some IPCs have entire payload found within RX header instead. Content and value of said header is context dependent and may vary between firmware versions and target platform. Current model does not allow such IPCs to function at all. Rather than appending yet another parameter to an already long list of such for sst_ipc_tx_message_XXXs, declare message container in form of struct sst_ipc_message and add them to parent's ipc_message declaration. Align haswell, baytrail and skylake with updated request-reply model and modify their reply processing functions to save RX header within message container. Despite the range of changes, status quo is achieved.

* ASoC: Intel: Skylake: Merge skl_sst and skl into skl_dev structCezary Rojewski2019-07-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Skylake driver is divided into two modules: - snd_soc_skl - snd_soc_skl_ipc and nothing would be wrong if not for the fact that both cannot exist without one another. IPC module is not some kind of extension, as it is the case for snd_hda_ext_core which is separated from snd_hda_core - legacy hda interface. It's as much core Skylake module as snd_soc_skl is. Statement backed up by existence of circular dependency between this two. To eliminate said problem, struct skl_sst has been created. From that very momment, Skylake has been plagued by header errors (incomplete structs, unknown references etc.) whenever something new is to be added or code is cleaned up. As this design is being corrected, struct skl_sst is no longer needed, so combine it with struct skl. To avoid ambiguity when searching for skl stuff (struct skl *skl) it has also been renamed to skl_dev. No functional changes.

* ASoC: intel: Replace kthread with workTakashi Iwai2016-11-301-3/+1
| | | | | | | | | | | | | | The usage pattern of kthread worker in Intel SST drivers can be replaced gracefully with the normal workqueue, which is more light- weight and easier to manage in general. Let's do it. While in the replacement, move the schedule_work() call inside the spinlock for excluding the race, too.

* ASoC: Intel: Add sst_ipc_tx_message_nopmVinod Koul2016-11-031-0/+3
| | | | | | | | | | | | | | | | | If the DSP is in low power mode, it needs to be woken up by a "wake" IPC to set it into the D0 state before we can send any other IPC command. The call flow is that the driver calls sst_ipc_tx_message_wait() to send any IPC and this call checks if the device is in low power mode and in that case we need to send the wake IPC. So add a new IPC nopm variant which can be called from driver and doesn't check for power state (as we already know that) and avoids circular dependency of again checking power state.

* ASoC: Intel: Refactor common IPC/mailbox code into generic APIsJin Yao2015-04-101-0/+91
Currently in Intel SST driver, some similar IPC/mailbox processing code are used in different platforms (e.g. in baytrail/broadwell). This patch extracts the common code and creates new files (sst-ipc.c/sst-ipc.h) to contain the common code and provide the generic APIs for IPC/mailbox processing.
