The MAX20830 provides 2.7V to 16V input, 0.4V to 5.8V output, and up to 30A output current. It supports monitoring of input/output voltage, output current, and temperature via PMBus. Datasheet: https://www.analog.com/en/products/max20830.html Signed-off-by: Alexis Czezar Torreno --- Changes in v2: - bindings: - did not add interrupt, smbalert pin does not exist in device. - added allof with ref to regulator.yaml - changed additionalprop to unevaluatedprop - device node name in example changed to regulator - driver: - max20830.rst: Added missing in2_alarm - max20830.c: - added missing quotes in MODULE_IMPORT_NS - added comment on why i2c_smbus_read_i2c_block_data is used - first byte of buffer used as length instead of the return value - "unsupported device" log now does not print first byte of buffer - Link to v1: https://lore.kernel.org/r/20260414-dev_max20830-v1-0-210d3f82c571@analog.com --- Alexis Czezar Torreno (2): dt-bindings: hwmon: pmbus: add max20830 hwmon: (pmbus/max20830) add driver for max20830 .../bindings/hwmon/pmbus/adi,max20830.yaml | 61 +++++++++++++++ Documentation/hwmon/index.rst | 1 + Documentation/hwmon/max20830.rst | 49 ++++++++++++ MAINTAINERS | 9 +++ drivers/hwmon/pmbus/Kconfig | 9 +++ drivers/hwmon/pmbus/Makefile | 1 + drivers/hwmon/pmbus/max20830.c | 86 ++++++++++++++++++++++ 7 files changed, 216 insertions(+) --- base-commit: fb447217c59a13b2fff22d94de2498c185cd9032 change-id: 20260414-dev_max20830-9460b92cf6aa Best regards, -- Alexis Czezar Torreno
