From 4d08b3634fe824409e75696635fb27204b8d4720 Mon Sep 17 00:00:00 2001 From: Matti Vaittinen Date: Mon, 15 Dec 2025 15:17:17 +0200 Subject: dt-bindings: regulator: ROHM BD72720 The ROHM BD72720 is a new PMIC with 10 BUCk and 11 LDO regulators. The BD72720 is designed to support using the BUCK10 as a supply for the LDOs 1 to 4. When the BUCK10 is used for this, it can be set to a LDON_HEAD mode. In this mode, the BUCK10 voltage can't be controlled by software, but the voltage is adjusted by PMIC to match the LDO1 .. LDO4 voltages with a given offset. Offset can be 50mV .. 300mV and is changeable at 50mV steps. Add 'ldon-head-microvolt' property to denote a board which is designed to utilize the LDON_HEAD mode. All other properties are already existing. Add dt-binding doc for ROHM BD72720 regulators to make it usable.

There are two different use-cases for this type of charging. At least some Li-Ion batteries can benefit from very slow, constant current, pre-pre phase 'trickle-charging', if a battery is very empty. Some other batteries use top-off phase 'trickle-charging', which is different from the above case. The battery bindings use the term 'trickle-charge' without specifying which of the use-cases properties are addressing. This has already caused some confusion. Clarify that the 'trickle-charge-current-microamp' refers to the first one, the "pre-pre" -charging use-case.
