Subject: [PATCH v4 0/2] Add LT8491 driver
Date: Tue, 10 Nov 2026 10:31:38 +0800 [thread overview]
Message-ID: <20261110023140.468-1-johnerasmusmari.geronimo@analog.com> (raw)
The LT8491 is a buck-boost switching regulator battery charger that
implements a constant-current constant-voltage (CCCV) charging profile.
Changes since v3:
https://lore.kernel.org/all/20261029073012.1498-1-johnerasmusmari.geronimo@analog.com/
- dt-bindings: add Krzysztof Kozlowski's Reviewed-by.
- driver: set psy_cfg.fwnode so that the power supply gets a firmware
node (sashiko-bot).
Tested on a DC2703A-A-KIT evaluation board with a Raspberry Pi 4B
(6.12-based vendor kernel) with no battery connected; charging was not
tested, nor was the -ENODATA handling of the not-measured and
thermistor-disconnected temperature values. Build-tested against the
power-supply for-next tree.
