Is the ACPI probe smart enough to deal with two different drivers
registering for the *same* HID?

I haven't seen any precedent, e.g. the RT6777 uses a different ACPI HID
for its I2C and SPI modes.

These should be dropped, these are registers for the firmware
peripherals and will never be used from the driver.

Doesn't seem right to have an ALSA control to enable the boost
converter. Controlling high voltages is definitely something that
should be under kernel control.

Ditto here for the boost voltage.

Likewise this weak FET stuff, it looks hardware dependent and
probably shouldn't be in userspace control, the datasheet states:

  The strength of the output drivers is reduced when operating in a
  Weak-FET Drive Mode and must not be used to drive a large load.

Which strongly implies to me this should be in DT/driver control.

Again temperature warnings don't feel like they should be getting
set through an ALSA control.

You sure this is necessary? The core should do this for us, its
only necessary if the regmap is on a different struct device to
the CODEC which isn't the case in this driver. Also if this is
necessary it should be using snd_soc_component_init_regmap.

Probably don't need quite so many blank lines here.

Any reason to not just parse this before enabling the supplies?
Parsing the pdata shouldn't require the hardware to be enabled
all the settings are being applied through set_pdata later on,
means you can just return on an error as well rather than having
to disable the supplies again. On the topic of errors any reason
this sets all errors to ENODEV, why not return the error that
cs35l41_handle_pdata returned? Seems more helpful.

Thanks,
Charles

I2C and SPI buses, when they are looking for a driver with an ID that 
matches a device declared in ACPI, will iterate over drivers that belong 
to the bus only (bus_for_each_drv()). It is not possible for an I2C 
driver to be matched during SPI device enumeration or vice versa.

David

That's good but that use of the same HID for two different solutions is
still be problematic. On ACPI solutions, we use the HID as a key to
identify what machine driver to load, see e.g. snd_soc_acpi_find_machine().
By using the *same* HID, you will prevent that machine detection from
uniquely identifying what mode is used, and force the machine detection
to be expanded with e.g. DMI-based quirks. It's really far from ideal
for integrators. The only case where this would work with impacts on the
machine selection would be if the choice of the SPI and I2C modes had no
impact on the functionality of the device, but is this really the case?

We know that HIDs are required to setup machine-specific stuff, but that
doesn't prevent having a generic ID string. We still allocate a generic
ACPI ID for the part. As machine-specific HIDs are likely, there's no
strong reason to allocate two generic IDs for the same part.

Unfortunately we don't have a crystal ball to be able to include now all
the machine-unique HIDs that will be allocated in the future, so they
will have to be added when they exist.

I can't think what you'd need to setup differently in a machine driver
for I2C versus SPI control. Do you have the bus ID hardcoded into your
machine drivers for some reason?

You can always add the bus type as a key if you really need to?

Usually that's the case for CODECs, it's just going to be a question of
how fast the I/O is, physical design considerations and what interfaces
you have available.  It'll be limiting for some applications of course
(slow firmware downloads for example) but given the way these things are
built I'd be fairly surprised to see something actively gated off.  If
you look at the I2C and SPI bus handling for individual CODECs they're
usually extremely thin wrapper that just pass a regmap into common code
with nothing else done conditionally.

I could but this adds more work.

In general yes, but the SPI can be used for faster upload of e.g.
history data on capture, something I2C is not capable of. That would
e.g. expose new dailinks in a machine driver. the RT5677 is the typical
example of this.

Anyways, I am not going to lay on the tracks for an HID, BIOS folks
usually get them wrong anyways.

Not necessary. As far as I can tell this is just a relic of something 
long since refactored.

I agree with all the other comments as well and I will include in v6.
