ASoC: SOF: Intel: bdw/byt/pci-tng: Do not set the load_module ops

2022-04-29T12:06:14Z

The used firmware loader (snd_sof_load_firmware_memcpy) can use the generic module loading, which is by default uses the same implementation as the snd_sof_parse_module_memcpy. No need to set the callback for these platforms.

ASoC: SOF: Intel: Do not set fw_ready callback

2022-04-25T12:58:48Z

The fw_ready is handled internally to ipc3 and the callback no longer in use.

ASoC: SOF: Intel: add IP identifier

2022-04-19T11:03:46Z

This patch adds an IP identifier for each Intel platform. The identifier will be used to select different code branches or constants.

ASoC: SOF: remove const qualifier for 'struct snd_sof_dsp_ops'

2022-04-19T11:03:39Z

Now that we start having multiple platforms with minor variants, the use of the const qualifier for 'dsp_ops' is starting to be sub-optimal: the structures are copied across platforms, with only a couple of members that differ. This patch removes the const qualifier without any functionality changes, and adds an optional initialization callback. In follow-up patches, the dsp_ops will revisited for Intel HDaudio platforms, with the differences added programmatically over a common baseline.

ASoC: SOF: add IPC-dependent file names

To avoid misleading file names, use different names for INTEL_IPC4 firmware files.

ASoC: SOF: add default IPC capability and file paths

2022-04-19T11:03:33Z

This patch adds a default IPC type for each platform, along with file paths to be used for each IPC type. To make reviews simpler, we only modify platform descriptors in this table, the information will be used in the next patch. The Intel IPCv4 is only supported on Intel platforms after APL, and not by default. In follow-up patches, support for SKL and KBL will be added, and in those two cases the IPCv4 will be the default (and only supported mode).

ASoC: SOF: add path indirection to each IPC type

2022-04-19T11:03:32Z

With the addition of the IPCv4, we need the ability to select different paths for firmware and topologies. First add an indirection. Follow-up patches will add mechanisms to select a default IPC or override it. No functionality change in this patch.

ASoC: SOF: Make Intel IPC stream ops generic

2021-10-07T15:57:54Z

This operations should be generic as there is nothing Intel specific. This works well for NXP i.MX8 stream IPC ops. We start by moving sof/intel/intel-ipc.c into sof/stream-ipc.c and rename the functions to be generic. Notice that we use newly introduced snd_sof_dsp_mailbox_read instead of sof_mailbox_read, to make sure that we are not bound to existing MMIO memory access, and we allow platform to implement their own memory access routines.
