-The 'loop1' gpio pin controls two relays, which are either in loop position,

+  The TSE-850 is an FM Transmitter Station Equipment, designed to generate
+  baseband signals for FM, mainly the DARC subcarrier, but other signals
+  are also possible.
+
+  The schematics explaining the gpios are as follows::

Bzzzt, this is no longer the case. This binding is orphaned (as is its
corresponding driver).

So we can remove them?
