Kernel driver lx1308
====================
Supported chips:
* Luxshare LX1308
Prefixes: 'lx1308'
Addresses scanned: -
Datasheet: Datasheet is not publicly available.
Author: Brian Chiang <chiang.brian@inventec.com>
Description
-----------
The LX1308 is a high-efficiency, non-isolated, regulated 12V, 860W,
digital DC/DC power module. The module operates from a 40V to 60V DC
primary bus and provides a 12V regulated output voltage. It can deliver
up to 860W continuous and 1300W in transient.
The module has slow OCP and fast OCP. If the module output current is higher
than slow OCP set point and the lasting time is also longer than the delay,
the module will shut down and retry 3 time, if the fault still exists then
module enter latch mode.
If the module output current is higher than fast OCP set point then it shut
down and enter latch mode.
The driver is a client driver to the core PMBus driver.
Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers.
Usage Notes
-----------
This driver does not auto-detect devices. You will have to instantiate the
devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
details.
