From 78fa372ec9f7e26b8af715a90d44fb537bbd4425 Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Thu, 20 Jun 2019 20:12:40 +0200 Subject: superio/nuvoton/nct6791d: Add symbol to select COM port Like the NCT6776, the NCT6791D has muxed COMA/GPIO8 functions. Since it requires setting different bits, add a new Kconfig symbol to do it.
