[PATCH 0/4] net: constify struct regmap_bus/regmap_config

[Javier Carrasco]

This series adds the const modifier to the remaining regmap_bus and
regmap_config structs within the net subsystem that are effectively
used as const (i.e., only read after their declaration), but kept as
writtable data.

[PATCH 2/4] net: ti: icss-iep: constify struct regmap_config

[Javier Carrasco]

`am654_icss_iep_regmap_config` is only assigned to a pointer that passes
the data as read-only.

Add the const modifier to the struct and pointer to move the data to a
read-only section.
