SubjectRe: [PATCH v2 12/20] dt-bindings: reset: npcm: Add support for NPCM8XX
Hi Krzysztof,

Thanks for your clarification.

We can remove the dt-binding file and use numbers in the DTS,
appreciate if you can answer few additional questions:
1. Do you suggest adding all NPCM reset values to the NPCM reset
document or the reset values should describe in the module
documentation that uses it?
2. Some of the NPCM7XX document modules describe the reset value they
use from the dt-binding for example:
https://github.com/torvalds/linux/blob/master/Documentation/devicetree/bindings/iio/adc/nuvoton%2Cnpcm750-adc.yaml#L61
If we remove the NPCM8XX dt-binding file should we describe the
NPCM8XX values in the NPCM-ADC document file?

Best regards,

Tomer
