Late to the conversation, so i might be asking questions already asked... So the PLD has restrictions? You have a collection of GPOs and a collection of GPIs? You don't have an GPIOs? > > > > + > > > > +properties: > > > > + compatible: > > > > + enum: > > > > + - delta,tn48m-gpio-sfp-tx-disable > > > > + - delta,tn48m-gpio-sfp-present > > > > + - delta,tn48m-gpio-sfp-los Do these names have any real significant? Are you really forced to connect the SFP cage in this dedicated manor? Is there any reason why i cannot use a GPO to control an LED? A GPI for a button? Andrew
