2.34.1
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 v7:
- 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
- remove gain kcontrol for each device
- 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.

2.34.1
PCM6240 family chips are popular among audio customers, in spite of only a
portion of the functionality of codec, such as ADC or DAC, and so on, for
different Specifications, range from Personal Electric to Automotive
Electric, even some professional fields. Yet their audio performance is far
superior to the codec's, and cost is lower than codec, and much easier to
program than codec.

Change in v7:
- Rewrite the subject to match something similar to other commits.
- And none of them are compatible with something.
- minItems, then maxItems.
- Drop reset-gpios description
- Remove the repeated reg descriptions and reg constraints.
- Drop redundant spaces.
- Add missing line breaks between blocks and additionalProperties.
- Correct compatibility issue on adc6120 and pcm6240.
- 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. Simply one or two register settings can enable
them to work. Init for these chips are hardware reset or software reset.
As to some audio filter params for internal filters, it is up to the
special user cases, which can be saved into the bin file. The default
value also can work well.
- Add blank line before reg.
- remove unneeded items and if branches.
- Add missing compatible devices, such as adc6120, etc.
- Add necessary people into the list for DTS review
- correct misaligned.
- simplify the compatibility
- remove sound-name-prefix and revert back
- Add review information

All these changes in v7 and you still kept Rob's review? I think either

Since Rob's review, nothing changed in yaml. Even in this patch, only removed kcontrol interfaces
in the code and added the mixer-test report in cover-letter as Mark suggested, which is no effect
on yaml file.
