[PATCH 0/8] ASoC/soundwire: revisit interrupt and lcount handling

[Bard Liao]

The code in drivers/soundwire/intel_init.c is hardware-dependent and the
code does not apply to new generations starting with MeteorLake. Refactor
and clean-up the code to make this intel_init.c hardware-agnostic and
move all hardware-dependencies in the SOF driver using chip descriptors.

The ASoC patches are dependent on some patches that are applied to ASoC
tree recently. So, this series won't apply to SoundWire tree. @Vinod Could
you Ack if it looks good to you, and lets go through ASoC tree?

[PATCH 1/8] soundwire: intel_init: remove useless interrupt enablement in interrupt thread

[Bard Liao]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

When the code reaches the SoundWire interrupt thread handling, the
interrupt was enabled already, and there is no code that disables it
-> this is a no-op sequence.

[PATCH 2/8] ASoC: SOF: Intel: hda: add per-chip enable_sdw_irq() callback

[Bard Liao]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

Different generations of Intel hardware rely on different programming
sequences to enable SoundWire IP. In existing hardware, the SoundWire
interrupt is enabled with a register field in the DSP register
space. With HDaudio multi-link extensions registers, the SoundWire
interrupt will be enabled with a generic interrupt enable field in
LCTL, without any dependency on the DSP being enabled.

Add a per-chip callback following the example of the check_sdw_irq()
model already upstream.

Note that the callback is not populated yet for MeteorLake (MTL) since
the interrupts are already enabled in the init. A follow-up patch will
move the functionality to this callback after a couple of cleanups.

[PATCH 3/8] ASoC: SOF: Intel: mtl: factor interrupt enable/disable interrupt functions

[Bard Liao]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

The offsets and sequences are identical for interrupt enabling and
disabling, we can refactor the code with a single routine and a
boolean.

[PATCH 4/8] ASoC: SOF: Intel: mtl: move SoundWire interrupt enabling to callback

[Bard Liao]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

There's no real rationale for enabling the SoundWire interrupt in the
init, this can be done from the enable_sdw_irq() callback.

[PATCH 4/8] ASoC: SOF: Intel: mtl: move SoundWire interrupt enabling to callback

[Bard Liao]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

There's no real rationale for enabling the SoundWire interrupt in the
init, this can be done from the enable_sdw_irq() callback.

[PATCH 5/8] ASoC: SOF: Intel: hda: add callback to check SoundWire lcount information

[Bard Liao]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

The number of links is stored in different registers depending on the
IP version, add sdw_check_lcount() callback. This callback only checks
that the number of links supported in hardware is compatible with the
number of links exposed in ACPI _DSD properties.

[PATCH 7/8] soundwire: intel_init: remove check on number of links

[Bard Liao]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

The number of links is checked with a chip-dependent helper in the
caller, remove the check in drivers/soundwire/intel_init.c

This change makes intel_init.c hardware-agnostic - which is quite
fitting for a layer that only creates auxiliary devices.

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

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
