I have a Zotac CI321 mini-PC which uses a Nuvoton 6779D (or compatible) Super-IO for infrared remote control. The normal CIR part works flawlessly however I can't access the wakeup registers. Resource allocation works normal, /proc/ioports reports: 0220-022e : nuvoton-cir-wake 02e0-02ee : nuvoton-cir Also configuring the logical device works normal as can be seen in the debug output. However all reads to this ioport region fail. I tried manually changing the ioport region but this didn't help either. Meanwhile I'm wondering whether there might be stripped down versions of this chip w/o the wake functionality as I'm running out of other ideas. Appreciate any hint.
