Subject: [PATCH v3 0/6] Add cs42l43 PC focused SoundWire CODEC

This patch chain adds support for the Cirrus Logic cs42l43 PC focused
SoundWire CODEC. The chain is currently based of Lee's for-mfd-next
branch.

Thanks,
Charles

Subject: [PATCH v3 3/6] mfd: cs42l43: Add support for cs42l43 core driver

The CS42L43 is an audio CODEC with integrated MIPI SoundWire interface
(Version 1.2.1 compliant), I2C, SPI, and I2S/TDM interfaces designed
for portable applications. It provides a high dynamic range, stereo
DAC for headphone output, two integrated Class D amplifiers for
loudspeakers, and two ADCs for wired headset microphone input or
stereo line input. PDM inputs are provided for digital microphones.

The MFD component registers and initialises the device and provides
PM/system power management.

Is this required anymore?

We don't tend to like #ifery in C files.

Why is it required?

And why not just put them were they're consumed?

How often are you realistically going to enable these? Can you do
without them and just add some printks when debugging? Seems a shame to
dirty the code-base with seldom used / questionably helpful LoC.

Grammar please. Some capital letters missing there.

Why 20?

What's shadow? Comment please.

Stage 3 what?

Perhaps some simple function headers would help?

Apologies but just to be super clear you want this to look like:

I was not aware of it not being required, I think it will still
be used for the purposes of module naming. Perhaps someone more
knowledgable than me can comment?

The trouble is the cs42l43_reg_default array and the array size.
There is no good way to statically initialise those two fields
from a single array in both the I2C and SDW modules.

I mean I use them all the time they are very helpful. But yeah I
can just add them each time I need them its just a pain, but I
guess since you are the second person to comment I will accept
that wanting to easily turn on debug is not a feature we are keen
on.

Because that is what the hardware needs, I assume this will be
covered when I turn all number in to defines.

You mean add some kernel doc for these functions, right? Assuming
that is what you mean, will do.

Since this table isn't providing any information which cannot be derived
from the other (OF, ACPI) tables, the I2C subsystem should be able to
obtain it from those sources instead.

Can you have a little think for another way to solve this please?

Sure, during development. Now the driver is authored however, how often
are you likely to turn it back on. Besides, this isn't real debug
information with dynamically obtained values and useful information,
it's a function call trace which can be obtained from other sources,
such as ftrace and the like.

Please make that clear. I don't see any documentation or pointers here.

I'd suggest not using kernel-doc formatting, but that type of thing,
yes.

Sorry I literally just sent a v4 then saw this email. I will test
removing this table and send a v5.

I will have another go at it, if memory serves the vague options
were:

1) this approach
2) some sort of horrible #include to put the defaults array in
both modules, although I would really prefer to avoid this one.
3) dynamically allocate the regmap_configs so those two fields
can be filled in with non-static data.

If I fail to come up with an option 4 would you prefer 1 or 3?
Well or 2 but I really would prefer not to do 2.

Ok I will remove the kernel doc bits for v5.

Well or just leave both in actually I guess perhaps that is
simplest.
