Subject: [RFC PATCH 0/2] mfd: syscon: declare holes in syscon register maps

In reply to mail: Holes management in syscon driver. 

Hi Dong, Maxime, Lee, all,

Regmap also offers .rd_table and .wr_table structures that can be used to
specify valid ranges within agiven regmap configuration.

This patch uses these structures to declare holes in a syscon instance.
It takes the description from DT, and fills in the structures accordingly.

Can I have your opinion on this implementation ?

Thanks and Regards,
Seraphin
