This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.
If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:
pip3 install dtschema --upgrade
Please check and re-submit.

Add conditionals depending on compatibles to document variants specs:
- possible reg addresses
- whether audio-gain-db is supported or not
- maximum number of leds
- led-max-microamp values

This should be squashed with patch #2. You document new variants with
their constraints. At least the constraints respective to these newly
added variants.
Best regards,

In order to add real support for is31fl3190, is31fl3191 and is31fl3193,
rename variant-dependent elements to not use 319X where needed.
3190 suffix is used for is31fl3190, is31fl3191 and is31fl3193 circuits.
3196 suffix is used for is31fl3196 and is31fl3199.
Those two groups have different register maps, current settings and even
a different interpretation of the software shutdown bit:
https://lumissil.com/assets/pdf/core/IS31FL3190_DS.pdf
https://lumissil.com/assets/pdf/core/IS31FL3191_DS.pdf
https://lumissil.com/assets/pdf/core/IS31FL3193_DS.pdf
https://lumissil.com/assets/pdf/core/IS31FL3196_DS.pdf
https://lumissil.com/assets/pdf/core/IS31FL3199_DS.pdf
Rename variables, stuctures and defines in preparation of the splitting.
No functional nor behaviour change.

Allow setting chips' specifics in chipdef struct by adding fields for:
- the reset register address
- a pointer to a regmap_config struct
- a pointer to a brightness_set function
- current default, min and max values
- a boolean to distinguish 319{0,1,3} and 319{6,9} chips
and use those fields in places where distinction has to be made.
The fields for 319{0,1,3} still point to 319{6,9} values.
No functional change.
