In this scenario we cannot assign one configuration per channel, some channels will have to share configurations like, ODR, gain and filter parameters. Allow the user to specify channels and configurations separately in device-tree and assign, if needed, the same configuration to multiple channels. If two channels share the configuration changing the sampling rate of one will change the sampling rate of the other too.
