[PATCH 0/8] ASoC: SOF: Intel and IMX updates for 5.8
Hi,
here's a series of minor fixes and improvements to SOF. Add support for smart amplifier component type. Cover more systems by relaxing match rules for the generic Soundwire machine driver. Fix issues with driver unload and address a few compiler warnings.
Daniel Baluta (2): ASoC: SOF: Do nothing when DSP PM callbacks are not set ASoC: SOF: define INFO_ flags in dsp_ops
Keyon Jie (1): ASoC: SOF: topology: add support to smart amplifier
Marcin Rajwa (2): ASoC: SOF: add a power_down_notify method ASoC: SOF: inform DSP that driver is going to be removed
Pierre-Louis Bossart (2): ASoC: SOF: imx: make dsp_ops static ASoC: SOF: imx: make imx8m_dsp_ops static
randerwang (1): ASoC: SOF: Intel: sdw: relax sdw machine select constraints

This provides a better separation between runtime and PM sleep callbacks.
Only do nothing if given runtime flag is set and calback is not set.
With the current implementation, if PM sleep callback is set but runtime callback is not set then at runtime resume we reload the firmware even if we do not support runtime resume callback.

This patch adds a snd_sof_dsp_power_down_notify() method which aims to prepare the DSP for the upcoming power down. This new function make use of SOF_IPC_PM_CTX_SAVE message.

From: Marcin Rajwa marcin.rajwa@linux.intel.com
This patch invokes the DSP power down notifier to inform DSP that driver is going to be removed. The module removal entails DSP power down, disabling of IRQs and more. Therefore it is highly recommended to inform the DSP about this upcoming event.
Due to hardware limitations on some Intel platforms it is necessary to power gate all LPSRAM banks that were enabled prior to controller reset. Otherwise, an attempt to write LPSRAM control registers may have no effect.

Add smart amplifier component support, which is designed as another new type of process component and used for speaker protection algorithm integration.

On some platforms such as Up Extreme all links are enabled but only one link can be used by external codec. Instead of exact match of two masks, first check whether link_mask of mach is subset of link_mask supported by hw and then go on searching link_adr.

In the past, the INFO_ flags such as PAUSE/NO_PERIOD_WAKEUP were defined in the SOF PCM core, but that was changed since commit 27e322fabd508b ("ASoC: SOF: define INFO_ flags in dsp_ops")
Now these flags must be set in DSP ops.

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
