Help text

Expose additional WRITE-able debugfs files in the client's pmbus debugfs directory, /sys/kernel/debug/i2c/i2c-<bus>/<bus>-<addr>/

These are provisioning and bring-up aids. On many designs the MPQ8646 powers the SoC core rail, so a wrong write can brown out or permanently mis-provision the board.

WARNING: Wrong register writes can and likely will physically damage or destroy the chip and/or the board.

It shall never be set in a production, shipping, or default configuration.

If unsure, say N.
