If I understand Bjorn's reply on
https://patchwork.kernel.org/patch/10575335/ correctly it is planned
to use the 'pdc-global' compatible string in the future in some sort
of MFD driver for the 'PDC Global' IP block, which then instantiates
other drivers like the reset controller. In this case I agree that
'pdc-global' seems a reasonable choice.
