Add support for LT3074 low voltage linear regulator
|
expand
|
Introduce hardware monitoring and regulator support for LT3074. The component is an ultrafast, ultralow noise 3A, 5.5V dropout linear regulator with a PMBus serial interface that allows telemetry for input/output voltage, output current, and die temperature. It has a single channel and requires a bias voltage which can be monitored via manufacturer-specific registers. Signed-off-by: Cedric Encarnacion <cedricjustine.encarnacion@analog.com> --- Changes in v2: * Separated dt-binding for LT3074. * Added __maybe_unused attribute to of_device_id. This addresses kernel test robot warning. * Added entry to MAINTAINERS. - Link to v1: https://lore.kernel.org/r/20250124-upstream-lt3074-v1-0-7603f346433e@analog.com --- Cedric Encarnacion (2): dt-bindings: hwmon: pmbus: add lt3074 hwmon: (pmbus/lt3074): add support for lt3074 .../bindings/hwmon/pmbus/adi,lt3074.yaml | 64 +++++++++++ Documentation/hwmon/index.rst | 1 + Documentation/hwmon/lt3074.rst | 72 ++++++++++++ MAINTAINERS | 9 ++ drivers/hwmon/pmbus/Kconfig | 18 +++ drivers/hwmon/pmbus/Makefile | 1 + drivers/hwmon/pmbus/lt3074.c | 122 +++++++++++++++++++++ 7 files changed, 287 insertions(+) --- base-commit: 8df0f002827e18632dcd986f7546c1abf1953a6f change-id: 20250124-upstream-lt3074-123384246e0b Best regards,
