Remove SEC S5M MFDs with no compatibles

[PATCH 0/2] Remove SEC S5M MFDs with no compatibles

Posted by David Virag 2 years, 7 months ago

The S5M8751 and S5M8763 MFD PMICs have no compatibles, and board file
support for them was removed, resulting in essentially no way for these
chips to be used anymore (unless they get dt compatibles).
They seemingly have never been in any board files upstream and I only
found references to the SM8751 being on the SMDK6450 board (which has
been unsupported for many years now) in a downstream Samsung Galaxy S2
kernel tree.

The patches should be applied in order.
