Subject[PATCH] mfd: Enable rbtree cache for wm831x devices
Date
Most useful with the regulators where we're doing a lot of read/modify/write
updates in potentially performance critical paths. Providing some defaults
would make this slightly better but this is a win right now.

Samuel, this depends on the regmap code in -next so I'd like to merge
it via regmap if that's OK with you?
