* ASoC: Intel: Remove skylake driverCezary Rojewski2024-08-191-428/+0
| | | | | | | | | | | | | | | | | | | | | | | The avs-driver found in sound/soc/intel/avs is a direct replacement to the existing skylake-driver. It covers all features supported by it and more and aligns with the recommended flows and requirements based on Windows driver equivalent. For the official kernel tree the deprecation begun with v6.0. Most skylake-drivers users moved to avs- or SOF-driver when AudioDSP capabilities are available on the platform or to snd-hda-intel (sound/pci/hda) when such capabilities are not. For the supported trees the deprecation begun with v5.4 with v5.15 being the first where the skylake-driver is disabled entirely. All machine board drivers that consume the DSP driver have their replacements present within sound/soc/intel/avs/boards/ directory.

* ASoC: Intel: skl-ssp-clk: Convert to platform remove callback returning voidUwe Kleine-König2023-03-201-4/+2
| | | | | | | | | | | | | | | | | | | The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

* | ASoC: Intel: Skylake: Merge skl_sst and skl into skl_dev structCezary Rojewski2019-07-241-2/+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.

* ASoC: Intel: Skylake: Fix NULL ptr dereference when unloading clk devAmadeusz Sławiński2019-06-251-9/+7
| | | | | | | | | | | | | | When driver is probed, we iterate over NHLT and check if clk entries are present. For each such entry we call register_skl_clk and keep the result in data->clk[]. Currently data->clk is sparsely indexed using NHLT table iterator, while when freeing we use number of registered entries. Let's just use data->avail_clk_cnt as index, so it can be reset back in unregister_src_clk.

* ASoC: Intel: Skylake: Add ssp clock driverSriram Periyasamy2018-01-261-0/+429
For certain platforms, it is required to start the clocks (mclk/sclk/fs) before the stream start. Example: for few chrome systems, codec needs the mclk/sclk to be enabled early for a successful clock synchronization and for few IVI platforms, clock need to be enabled at boot and should be ON always. Add the required structures and create set_dma_control ipc to enable or disable the clock. To enable sclk without fs, mclk ipc structure is used, else sclkfs ipc structure is used. Clock prepare/unprepare are used to enable/disable the clock as the IPC will be sent in non-atomic context. The clk set_dma_control IPC structures are populated during the set_rate callback and IPC is sent to enable the clock during prepare callback. This patch creates virtual clock driver, which allows the machine driver to use the clock interface to send IPCs to DSP to enable/disable the clocks.
