[PATCH 0/3] hwmon: (fs1603) Add driver for TDK FS160x and FS1006 uPOL converters

[Kevin Jia]

The TDK FS1603, FS1604, FS1606 and FS1006 are uPOL DC-DC converters with
an integrated inductor. They report input and output voltage, output
current and temperature over a proprietary I2C register map. They are not
PMBus devices, and their register numbers collide with PMBus command codes.

Patch 1 adds the TDK vendor prefix, patch 2 documents the parts as trivial
devices, and patch 3 adds a read-only hwmon driver. The model cannot be
detected from the part, so it is declared through the I2C device name or
the devicetree compatible. The FS1606-0600 and FS1606-2500 factory presets
scale telemetry differently from the base FS1606, so they have their own
compatibles.

Tested on FS1006-3300, FS1006-5000 and FS1606-0600 parts with the driver
backported to 6.12.
