[PATCH V4 1/2] ASoC: max98363: add soundwire amplifier driver

[PATCH V4 1/2] ASoC: max98363: add soundwire amplifier driver

[“Ryan]

From: Ryan Lee <ryans.lee@analog.com>

Added Analog Devices MAX98363 SoundWire Amplifier Driver.
The MAX98363 is a SoundWire peripheral device that supports
MIPI SoundWire v1.2-compatible digital interface for audio and
control data.

Signed-off-by: Ryan Lee <ryans.lee@analog.com>
---
Changes from v1:
  Removed the standard SoundWire registers from the amp register table.
  Removed .of_match_table and .acpi_match_table.
  Removed vdd/dvddio control.
  Removed unnecessary source port control in .read_prop.
  Removed legacy from I2S driver not used for SoundWire driver.
  Removed .shutdown, .bus_config, and unused functions.
  Sorted include files in alphabetical order.
Changes from v2:
  Changed .channels_max from 2 to 1.
  stream_config.ch_count is limited to .channels_max.
  Removed unused variables. rx_mask and slot from max98363_priv.
Changes from v3:
  No change

[PATCH V4 2/2] ASoC: dt-bindings: max98363: add soundwire amplifier

[“Ryan]

From: Ryan Lee <ryans.lee@analog.com>

Add dt-bindings information for Analog Devices MAX98363 SoundWire Amplifier

Signed-off-by: Ryan Lee <ryans.lee@analog.com>
---
Changes from v1:
  Fixed a syntax error for the 'dt_binding_check' build.
  Removed unnecessary properties.
  Added description about SoundWire device ID of MAX98363
Changes from v2:
  Removed the legacy from i2c/i2s driver and added SoundWire device ID info.
  Added missing information about DAI.
Changes from v3:
  Modified the commit message. Removed "This patch"
  Converted uppercase hex to lowercase hex
  Dropped 'sound-name-prefix'.
  Added unevaluatedProperties instead of additionalProperties

+
+description:
+  The MAX98363 is a SoundWire input Class D mono amplifier that
+  supports MIPI SoundWire v1.2-compatible digital interface for
+  audio and control data.
+  SoundWire peripheral device ID of MAX98363 is 0x3*019f836300
+  where * is the peripheral device unique ID decoded from pin.
+  It supports up to 10 peripheral devices(0x0 to 0x9).

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
