[PATCH 0/2] pmbus: Add MFR-specific commands for TPS544C20

[Romain Porte]

Hello,

This patchset provides a new driver for tps544c20 component with
enhanced features by using 2 new sysfs entries. The added features
are VREF_TRIM (MFR-specific) and STORE_USER_ALL commands for
voltage fine-tuning. Since the driver has new features compared
to the generic pmbus driver it can now replace it.

This is my very first try to send a patch to the Linux kernel
so be kind. I am aware that these modifications are very
component-specific but were tested successfully on it. Maybe
we should design something more generic here or afterwards.

Please review!

Romain
