I understand that you don't care, but from my perspective it must be addressed in generic fan properties, especially to ensure agreement on how 'pwms' is handled on a system where the fan mode is configurable, and how to select the fan speed on systems supporting DC fans.

Add common fan properties bindings to a schema. Bindings for fan controllers can reference the common schema for the fan child nodes: patternProperties: "^fan@[0-2]": type: object $ref: fan-common.yaml# Signed-off-by: Naresh Solanki <Naresh.Solanki@9elements.com> --- .../devicetree/bindings/hwmon/fan-common.yaml | 48 +++++++++++++++++++ 1 file changed, 48 insertions(+) create mode 100644 Documentation/devicetree/bindings/hwmon/fan-common.yaml
