[PATCH v1 0/5] Add support for CS35L63 Smart Amplifier

[PATCH v1 0/5] Add support for CS35L63 Smart Amplifier

[Stefan Binding]

CS35L63 is a Mono Class-D PC Smart Amplifier, with Speaker Protection
and Audio Enhancement Algorithms.

CS35L63 uses a similar control interface to CS35L56 so support for
it can be added into the CS35L56 driver.
CS35L63 only has SoundWire and I2C control interfaces.

Stefan Binding (5):
  ASoC: cs35l56: Add Index based on ACPI HID or SDW ID to select regmap
    config
  ASoC: cs35l56: Add struct to index firmware registers
  ASoC: cs35l56: Add Mute, Volume and Posture registers to firmware
    register list
  ASoC: cs35l56: Add initial support for CS35L63 for I2C and SoundWire
  ASoC: cs35l56: Read Silicon ID from DIE_STS registers for CS35L63

[PATCH v1 1/5] ASoC: cs35l56: Add Index based on ACPI HID or SDW ID to select regmap config

[Stefan Binding]

This is to prepare for further products using slightly different
regmap configs.

[PATCH v1 2/5] ASoC: cs35l56: Add struct to index firmware registers

[Stefan Binding]

Firmware based registers may be different addresses across different
device ids and revision ids. Create a structure to store and access
these addresses.

[PATCH v1 3/5] ASoC: cs35l56: Add Mute, Volume and Posture registers to firmware register list

[Stefan Binding]

Registers to set Mute, Volume and Posture are inside firmware,
which means they should be added to the list of registers set inside
firmware, in case they vary across Device or Revision.

These three registers are also used for controls, so additional
handling is required to be able to obtain and set the register inside
ALSA controls.

[PATCH v1 4/5] ASoC: cs35l56: Add initial support for CS35L63 for I2C and SoundWire

[Stefan Binding]

CS35L63 uses a similar control interface to CS35L56 so support for
it can be added into the CS35L56 driver.
New regmap configs have been added to support CS35L63.
CS35L63 only has SoundWire and I2C control interfaces.

[PATCH v1 5/5] ASoC: cs35l56: Read Silicon ID from DIE_STS registers for CS35L63

[Stefan Binding]

On CS35L63 the DIE_STS registers are populated by the Firmware from
OTP, so the driver can read these registers directly, rather than
obtaining them from OTP.

This is fine but note that this is the use case that the regmap_field_
APIs were created for, that also helps deal with things if anyone is
clever and resizes fields or shifts within registers.  It's purely a
question of taste if you want to use that.

The regmap_field stuff looks like a lot of unnecessary complexity and
overhead just for 6 registers with alternate addresses.

(In fact, the regmap_field stuff looks like an over-complex way of
solving a non-problem. The original commit is talking about replacing
masks and shifts "all over the code" to make the code neater. But
really, all those extra structs and pointers and allocated memory just
to replace a logical & or | ? Every struct regmap_field has a pointer
to the struct regmap !!?! So if I've got 100 fields there are 100 copies
of the struct regmap pointer that my driver already has.)

Yeah, like I say it's a taste thing.

It was for cases where the shifts and widths may also change, there's a
bit more than applying a mask.  Like you say it's got some overhead
hence the taste thing.

If you would prefer us to use it we'll make the changes.
If not, then we'd like to keep the code as it is for now and in
future we'll have a look at regmap_field.

Yes. If we had registers where the fields were moving around then there
would be better justification for using regmap_field.

Please delete unneeded context from mails when replying.  Doing this

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
