I think just drop custom_ prefix these handlers are for customization so this doesn't add any information 
Also here, I prefer that infrastructure changes will be in separate patches and not mangled with a specific device patch.

Is is designware specific ? Then should probably be DWC_ prefixed, if  not then shouldn't be defined here.
