Subject: [PATCH V10 1/4] dt-bindings: Add Rockchip rk817 battery charger support
Date: Fri, 26 Aug 2022 21:16:20 -0500 [thread overview]
Message-ID: <20220827021623.23829-2-macroalpha82@gmail.com> (raw)
In-Reply-To: <20220827021623.23829-1-macroalpha82@gmail.com>
From: Chris Morgan <macromorgan@hotmail.com>
Create dt-binding documentation to document rk817 battery and charger
usage. New device-tree properties have been added.
- rockchip,resistor-sense-micro-ohms: The value in microohms of the
sample resistor.
- rockchip,sleep-enter-current-microamp: The value in microamps of the
sleep enter current.
- rockchip,sleep-filter-current: The value in microamps of the sleep
filter current.
