Hi Andrew,

The purpose for the regmap table registered is to

provide a way which helps us to look up a specific

register on the switch through regmap-debugfs.


And not all ranges of register is defined

so I only include the meaningful ones in a sparse way

for the table.
I think in that case it might be nice to make regmap support optional in
order to avoid pulling in bloat on platforms that don't need it.

- Felix
The 2 relevant platforms are mips/ralink and arm/mediatek. both require 
regmap for the eth_sysctl syscon if they want to utilize the mtk_soc_eth 
driver which is a prereq for mt7530. so regmap cannot be optional here.

     John
