2019-08-08ASoC: Intel: Skylake: large_config_get overhaulCezary Rojewski1-1/+2
LARGE_CONFIG_GET is mainly used to retrieve requested module parameters but it may also carry TX payload with them. Update its implementation to account for both TX and RX data. First reply.header carries total payload size within data_off_sizefield. Make use of reply.header to realloc returned buffer with correct size. Failure of IPC request is permissive - error-payload may be returned, an informative data why GET for given param failed - and thus function should not collapse before entire processing is finished. Caller is responsible for checking returned payload and bytes parameters.

2019-07-24ASoC: Intel: Skylake: Merge skl_sst and skl into skl_dev structCezary Rojewski1-50/+2
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.

2018-03-13ASoC: Intel: Skylake: Disable clock and power gating during FW/LIB downloadSanyog Kale1-0/+3
In order to achieve better DMA performance and reduce download time for firmware and library, it is recommended to disable dynamic clock and power gating. In some scenarios, DMA may wait to accumulate more data and last chunk of data never gets completed if dynamic clock and power gating is kept enabled. This patch adds support to disable/enable dynamic clock and power gating and use it during firmware and library download.

2017-03-15ASoC: Intel: Skylake: Fix module load when module size > DMA buffer sizeJeeja KP1-0/+5
When module size > DMA buffer size, driver copies first chunk and waits for the BDL complete interrupt. BDL complete interrupt never occurs and wait time expires as module load IPC is not send to start the DMA from DSP. To fix the above issue need to follow the below steps: 1. After copying the first chunk, send the module load IPC to start the DMA. 2. Wait for the BDL interrupt. Once interrupt is received, copy the next chunk. 3. Continue step 2 till all bytes are copied. 4. When all the bytes are copied (bytes_left = 0), wait for module load IPC response 5. Handled module load IPC response messages, check the load module IPC response and wake up the thread to complete module load.
