From 761de79adc2ca529c9e4cc75cfc2f0ec542c5463 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Tue, 16 Nov 2021 12:02:07 +0100 Subject: [PATCH] dt-bindings: hwmon: add TI DC-DC converters Few Texas Instruments DC-DC converters on PMBus like TPS544B20 do not have bindings and are used only as hardware monitoring sensor. These devices are actually not trivial and can receive basic configuration (e.g. power up mode, CNTL pin polarity, expected input voltage), however devicetree support for configuration was never added. Therefore in current state the devices are used only in read-only mode and have trivial bindings, so document them to have basic dtschema tests.
