ASoC: SOF: Introduce fragment elapsed notification API

2021-10-07T15:57:57+00:00

This patch prepares the introduction of the compress API with SOF.

After each fragment is accepted by the DSP we need to inform
the userspace applications that they can send the next fragment.
This is done via snd_compr_fragment_elapsed.

Similar with the PCM case, in order to avoid sending an IPC before
the previous IPC is handled we need to schedule a delayed work to
call snd_compr_fragment_elapsed().

See snd_sof_pcm_period_elapsed.

To sum up this patch offers the following API to SOF code:
	* snd_sof_compr_init_elapsed_work
	* snd_sof_compr_fragment_elapsed

Note that implementation for compressed function is in a new file
selected via CONFIG_SND_SOC_SOF_COMPRESS invisible config option.
This option is automatically selected for platforms that support
the compress interface. For now only i.MX8 platforms support this.

For symmetry we introduce snd_sof_pcm_init_elapsed_work to setup
the work struct for PCM case.

ASoC: SOF: imx: Use newly introduced generic IPC stream ops

2021-10-07T15:57:56+00:00

This makes IMX use the newly introduced generic IPC ops
instead of imx specific ones, and removes the old IMX
ipc ops, as they are no longer needed.

ASoC: SOF: Introduce snd_sof_mailbox_read / snd_sof_mailbox_write callbacks

2021-10-07T15:57:53+00:00

We need to introduce snd_sof_mailbox_{read/write} in order to provide
a generic way for mailbox access. These routines are optional, each
platform can implement their own specific routines.

So far, all platforms use mmapped I/O thus they can use custom made
routines sof_mailbox_read / sof_mailbox_write that use MMIO.

ASoC: SOF: add error handling to snd_sof_ipc_msg_data()

2021-09-28T12:16:26+00:00

If an invalid stream is passed to snd_sof_ipc_msg_data() it won't
fill the provided object with data. The caller has to be able to
recognise such cases to avoid handling invalid data. Make the
function return an error when failing.

2021-09-17T12:17:47+00:00

From the name sof_arch_ops one can not decipher that these ops are DSP
architecture ops.
Rename it to dsp_arch_ops and change also the macro to retrieve the DSP
architecture specific ops as well.
