This should not be completely automatic as it may be disruptive. A selective reset may also be useful for debugging or diagnostics. This adds a separate reset operation which takes flags indicating the components to be reset. Drivers are allowed to reset only a subset of those requested, and must indicate the actual subset. This allows the use of generic component masks and some future expansion. Signed-off-by: Ben Hutchings Signed-off-by: David S.
