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.
