✨ NAME ✨

isagpio — ISA I/O mapped as GPIO 🦋

🌸 SYNOPSIS 🌸

isagpio0 at isa? port 0x78
isagpio1 at isa? port 0x80
gpio* at isagpio?

💜 DESCRIPTION 💜

So the isagpio driver is the little connector bestie that lets you access the 8-bit ISA I/O space through the gpio(4) framework. The way that works means you can make use of the simple GPIO devices that are connected directly to the ISA bus — iconic behavior, honestly 👑
