[PATCH 0/1] hwmon: (pmbus) Add support for Flex BMR316, BMR321, BMR350 and BMR351

[Daniel Nilsson]

Add support for BMR316, BMR321, BMR350 and BMR351 DC/DC converter
modules from Flex to the generic pmbus driver.

BMR492, BMR316, BMR321, BMR350 and BMR351 all use the same chip, which
has the deficiency that it presents a second phantom PAGE even though
the devices only have a single real PAGE/rail.  By explicitly
specifying the number of pages via driver_data, as is already in place
for BMR492, we avoid exposing the phantom PAGEs.

Update the documentation with a new datasheet URL.  The datasheets for
Flex BMRs are now only found via the product selector on flex.com.

The patch has been tested against BMR316, BMR321, BMR350 and BMR351.
