Hi Oskar,quoted
For LPC, the polarity should be set to 1, for eSPI the default of 0 is correct.Would there ever be a case where different SIRQs need different polarities? If not, we may want this to be global, rather than for each device (the VUART being one...)
Leave it per device. The way to configure this is completely device dependent. In fact for most devices it can only be done by the host via SIO. Cheers, Ben.
