3e5f73a062 hwmon: (pmbus/adp1050) Add support for adp1051, adp1055 and ltp8800 
Introduce hardware monitoring support for the following devices:

    ADP1051: 6 PWM for I/O Voltage, I/O Current, Temperature
    ADP1055: 6 PWM for I/O Voltage, I/O Current, Power, Temperature
    LTP8800-1A/-2/-4A: 150A/135A/200A DC/DC µModule Regulator

The ADP1051 and ADP1055 are similar digital controllers for high
efficiency DC-DC power conversion while the LTP8800 is a family of
step-down μModule regulators that provides microprocessor core voltage
from 54V power distribution architecture. All of the above components
features telemetry monitoring of input/output voltage, input current,
output power, and temperature over PMBus.

cdd30ebb1b module: Convert symbol namespace to string literal 
Clean up the existing export namespace code along the same lines of
commit 33def8498f ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

    awk -i inplace '

d8a66f3621 hwmon: Drop explicit initialization of struct i2c_device_id::driver_data to 0 
These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.

This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

04f175954d hwmon: (pmbus) Add driver for ADP1050 
Add support for ADP1050 Digital Controller for Isolated Power Supplies
with PMBus interface Voltage, Current and Temperature Monitor.

The ADP1050 implements several features to enable a robust
system of parallel and redundant operation for customers who
require high availability. The device can measure voltage,
current and temperature that can be used in different
techniques to identify and safely shut down an erroneous
power supply in parallel operation mode.
