[PATCH v2 0/6] soundwire/ASoC: abstract platform-dependent bases

[Bard Liao]

shim base and alh base are platform-dependent. This series suggests
to use variables for those bases. It allows us to use different bases
for new platforms.

v2:
 - Update the commit message of "soundwire: move intel sdw register
   definitions to sdw_intel.h"

Bard Liao (6):
  soundwire: move intel sdw register definitions to sdw_intel.h
  ASoC: SOF: intel: add sdw_shim/alh_base to sof_intel_dsp_desc
  ASoC: SOF: intel: hda: remove HDA_DSP_REG_SNDW_WAKE_STS definition
  ASoC: SOF: intel: move sof_intel_dsp_desc() forward
  ASoC: SOF: intel: add snd_sof_dsp_check_sdw_irq ops
  soundwire: intel: introduce shim and alh base

[PATCH v2 1/6] soundwire: move intel sdw register definitions to sdw_intel.h

[Bard Liao]

Those Intel sdw registers will be used by ASoC SOF drivers in the
following commits. So move those definitions to sdw_intel.h and it can
be visible to SOF drivers.

[PATCH v2 2/6] ASoC: SOF: intel: add sdw_shim/alh_base to sof_intel_dsp_desc

[Bard Liao]

sdw_shim_base and sdw_alh_base are platform-dependent. This change allow
us to define different sdw shim/alh base for each platform.

and use (hdev->desc->sdw_shim_base + SDW_SHIM_WAKESTS) instead.

[PATCH v2 6/6] soundwire: intel: introduce shim and alh base

[Bard Liao]

shim base and alh base are platform-dependent. Adding these two
parameters allows us to use different shim/alh base for each
platform.

The ASoC bits look fine to me, what't eh plan for merging this?  I can
apply to ASoC if people like, or should the Soundwire bits go via the
Soundwire tree?

Thanks Mark. Apply to ASoC or Soundwire are both fine to me.

I have acked the sdw parts, pls pick them thru ASoC tree. If we have
conflicts, I can merge the immutable tag from your tree.

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
