PCM6240 driver implements a flexible and configurable setting for register
and filter coefficients, to one, two or even multiple PCM6240 Family Audio
chips.
Signed-off-by: Shenghao Ding <[email protected]>

Change in v2:
- All these chips have only a portion of the functionality of codec,
such as ADC or DAC, and so on, but their audio performance is far
superior to the codec's, and cost is lower than codec, and much easier
to program than codec.

You could write all these functions a bit more simply if you rewrote
these error checks to return immediately on error, that way there's less
indentation and fewer paths later on.
if (dev_no >= pcm_dev->ndev)
return -EINVAL;
and so on. For the ones dealing with locking it can help to have a
single exit path but functions like this don't deal directly with the
locks.

The kernel coding style is that if one side of an if/else has { } both
should.

This will accept any configuration number, shouldn't there be some
validation here? The put functions doing regmap_update_bits() have
some limiting of values in the regmap_update_bits() but this just stores
the value directly.

It would be kind of nice if the device switching could be hidden inside
a custom regmap and we didn't have all this code duplication but I'm not
thinking of a way of doing that which doesn't just create complications
so probably this is fine.

There's the FIELD_GET() macro (and FIELD_SET() for writing values) - the
core predates them and hence doesn't use them, we might want to update
some time.

It might be better to request the firmware in the I2C probe rather than
in the ASoC level probe, that way there's more time for the firmware to
be loaded before we actually need it. That does mean you can't register
the controls immediately though so it may be more trouble than it's
worth.
Similarly for the reset, if we reset as early as possible that seems
better.

Perhaps -EBUSY instead? What the user is doing is valid.

Use _MAPLE for new devices, it's a more modern design with tradeoffs
that work better for most current systems.

Same comments applied as per previous version, please read my email and address
them.
