Hi Geert,

This patch series intends to incorporate the absent port pins P19 to P28,
which are exclusively available on the RZ/Five SoC.

I am submitting this series as an RFC (Request for Comments) as the port
pins P19 to P28 cannot be utilized as GPIO but can be utilized as
multiplexed pins. Additionally, certain attributes such as setting the
ISEL would necessitate a device tree property to indicate ISEL. Therefore,
before proceeding with the addition of comprehensive support, I would
appreciate some input on whether an alternative approach could be considered.

Cheers,
Prabhakar
