PCM6240 driver implements a flexible and configurable setting for register
and filter coefficients, to one, two or even multiple PCM6240 Family Audio
chips.

Change in v6:
- Use _MAPLE as cache_type for new devices, it's a more modern design with
tradeoffs that work better for most current systems.
- Rewrite error checks to return immediately on error in pcmdev_dev_read,
pcmdev_dev_write, pcmdev_dev_update_bits, and pcmdev_dev_bulk_write,
that way there's less indentation and fewer paths later on.
- Add profileid check in pcmdevice_set_profile_id, if invalid, set to
max-value or 0.
- fixed the return value as -EBUSY in pcmdevice_startup
- remove unused chn and chenend in pcmdevice_select_cfg_blk
- Be consistent with name, ret, rc, err.
- fixed compiling warning on iteration 4 invokes undefined behavior in
pcmdev_regbin_ready.
- remove unnecessary blank line between
"module_i2c_driver(pcmdevice_i2c_driver);" and
"static struct i2c_driver pcmdevice_i2c_driver".
- Move reset into i2c_probe and remove sw_rst callback.
- extract the put_vol and get_vol function as pcmdev_put_volsw and
pcmdev_get_volsw to reduce the red
- Simplify and rewirte gain_control_add code.
- Move gain kcontrol into codec_probe.
- Unified ret and rc to ret.
- correct of_gpio.h to gpio.h
- Add an array pcmdev_ctrl_name to store the gain control name.
- Move i2c_set_clientdata before sw_reset.
- Remove pcmdevice_startup, it seemed unnecessary once firmware_request was
move to i2c_probe.
- Add return value into pcmdev_profile_ctrl_add.
- If one side of the if/else has a braces both should.
- mixer-test kselftest to check the Kcontrol
- follow the same convention for error log
- Add sound-name-prefix for bin file name and control name
- use get_unaligned_be16 instead of be16_to_cpup and get_unaligned_be32
instead of be32_to_cpup for potentially broken alignment

So, I see why you're doing this naming thing for the per-device controls
- the device can (and is designed to) allow controlling multiple amps
with a single I2C write. However this is resulting in something that's
really awkward from an ALSA point of view, the names that are being
generated are very much not idiomatic for control names and probably
aren't going to be terribly meaningful for end users since they're not
associated with where the relevant outputs physically are. We could
require machines to provide names for everything but that's probably
going to be a miserable experience on x86 and is unhelpful even with DT
so having a default seems to make sense.
I think these should look more like ALSA names, so "I2C %d Device %d..."
though that does make things a bit longer.

For these I'm not clear why we don't just use the name, what's the goal
in having the device number in there?
I think it would make sense to do a version the driver with no user
visible controls (or at least none that need this name generation stuff)
and then make the controls an incremental patch, the driver would
obviously need both bits to be properly useful but it'd mean that the
simple bit could get reviewed and possibly merged separately to the
complicated bit which would probably be easier.
Please also send the output of mixer-test from a machine with this
driver in it as part of the cover letter, it'll make it easier to tell
what's going on.

You could also do this as a fallback (ie, try the specified name first
then fall bakc to the bus based numbering), that way if a name is added
later it won't break people's installs on upgrade.

Shouldn't there be some volatile registers if we have interrupts?

Hi Mark
For only single one device, all these seems redundant and makes uncomfortable
Many of my customers will have such cases as
Four pieces of Pcm6240s and three pieces of pcm6360s in the same i2c bus.
The chip name can help them identify the chip and set the right chip and the right channel.

You means to remove the kcontrols first. After the patch was accepted, add these
Kcontrols, right?

The problem is not with having the names, the problem is that the names
look nothing like how normal ALSA names for deduplicating controls look
- normally these are specified by the board and are human legible rather
than based on the numbers of buses inside the system.

Yes, or even just split the controls out so they're a later patch in the
series - no need to wait before sending the code, just sort it after the
rest of the driver.
