Jerome, maybe adding a bit of preamble like:

"Development boards from TI include the TPS65219 PMIC. Add support..."

Krzysztof, I'm the first to argue for descriptive/verbose changelogs,
but IMO, this is getting a little bit nit-picky.

The series adds a new driver, DTS and defconfig patches to enable
support the new driver. The "why" for changes to defconfig changes like
this are kind of implied/obvious, and there is lots of precedent for
changelogs of defconfig changes for simple drivers to simply say "enable
X and Y".

If my above suggesion is not enough, please make a suggestion for what
you think would qualify as an appropritate changelong that answers "why"
for a simple driver change.
