The bindings aren't perfect, for instance I couldn't find good descriptions for the vendor properties in the "charger" node of the ACT8945A because I am not familiar with the hardware and these properties were not documented anywhere. The YAML schemas are a bit different than what is described in the old text files, because these were sometimes wrong or had missing information. This is the case for the ACT8600 documentation, which specified the valid node names for the regulators, while the driver was expecting different names. This led to the current situation where we have two different boards using different names for the regulators: - arch/mips/boot/dts/ingenic/ci20.dts uses the names documented in the text file, - arch/mips/boot/dts/ingenic/gcw0.dts uses the names that the driver expects. In theory, the driver should be fixed to follow the documentation, and accept both naming schemes. In practice though, when the PMIC node was added to the ci20.dts board file, the names were already wrong in regards to what the driver expected, so it never really worked correctly and wasn't tested properly. Furthermore, in that board the consumers of the regulators aren't working for various other reasons (invalid GPIOs, etc.). For that reason, for the ACT8600 bindings I decided to only use the node names that the driver expects (and that gcw0.dts uses), instead of accepting both old and new names. A follow-up patch will update the CI20 board to use the new regulator names. Signed-off-by: Paul Cercueil --- v2: - Avoid | character in descriptions that can be single-line - Remove unevaluatedProperties when additionalProperties is also present - Remove useless inner parentheses in regular expressions - Rename I2C nodes to just... i2c - Remove node handles v3: - Fix alignment in examples - Drop useless status = "okay"; in examples - I set myself as the maintainer, which I only did because nobody else seems to care.
