Did this change in newer datasheets? What does the (B) part of the part number mean?

I'm not a YAML expert, but according to the yamllint tool, it would work with much less indentation: description: | There are 6 variants of the chip for various touch panel sizes and coverl len material Glass: 0.3mm--4.0mm [...] > + hycon,glove-enable: > + type: boolean > + description: Allows enabling or disabling glove setting. Small nit: Due to the way boolean properties work in DT, you can't really use the property to disable the glove setting (in order to disable the setting, you would explicitly not use the property). Perhaps: + description: Allows enabling the glove setting. I don't really know :) > + > + hycon,report-speed: > + description: Allows setting the report speed(i.e 0x64 => 100Hz). > + $ref: /schemas/types.yaml#/definitions/uint32 > + minimum: 0 > + maximum: 255 Please add a space before the opening parenthesis: + description: Allows setting the report speed (i.e 0x64 => 100Hz). Or perhaps like this: + description: Allows setting the report speed in Hertz. Thanks, Jonathan Neuschäfer
