To help users with connecting signal correctly, add a mapping note from signal name to polarity. In some of our schematics signal names (i.e. A and B) are used and some schematics use polarity signals. The mapping helps in easily translating from one scheme to the other (also relevant for e.g. USB to RS485/422 cables). Signed-off-by: Yannic Moog <y.moog@phytec.de>
