Renesas digital multiphase voltage regulators are capable of regulating output voltages that exceed the range that their Vsense pins can detect. In such applications, users may place a voltage divider between Vout and the Vsense pin for a given rail. However, the driver currently has no way of knowing if a voltage divider is being used which results in erroneous telemetry being reported through hwmon. This patch set defines a devicetree bindings schema for Renesas digital multiphase voltage regulators that are supported by the isl68137 driver to allow users to add voltage divider definitions for any rail powered by the device. This patch set also includes the required changes to the isl68137 driver to enable scaling Vout/Pout telemetry for rails with a defined voltage divider.
