2020-10-06ASoC: Intel: Skylake: Unassign ram_read and read_write opsCezary Rojewski
Skylake driver makes no use of ram_read or ram_write operation so remove the assignments. This prepares sound/soc/common/sst-dsp* for following removal of unused DSP operations.

2020-03-10ASoC: Intel: Skylake: Await purge request ack on CNLCezary Rojewski
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.

2020-03-10ASoC: Intel: Allow for ROM init retry on CNL platformsCezary Rojewski
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.

2019-07-24ASoC: Intel: Skylake: Merge skl_sst and skl into skl_dev structCezary Rojewski
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.
