CHVGPIO(4)

💖 NAME 💖

chvgpio — Intel Cherry View SoC GPIO controller. okay so bestie, this is the chvgpio(4) page from the Kernel Interfaces Manual, and it's literally here to make the GPIO situation make sense. 💅

✨ SYNOPSIS ✨

device gpio
device chvgpio

🦋 DESCRIPTION 🦋

chvgpio supports the GPIO controller that can be found in Intel's Cherry View SoC family. 🍓

The Cherry View SoC has 5 banks of GPIO pins: NORTH, EAST, SOUTHEAST, SOUTHWEST, and VIRTUAL. 👑

All but VIRTUAL are exposed to userland as /dev/gpiocN, where N is 0-3. so that's the vibe: userland gets the /dev/gpiocN nodes, and VIRTUAL stays backstage. 🙈

Pins in each bank are pre-named to match names in the Intel® Atom™ Z8000 Processor Series Vol 2. cute, right? the names are already done for you. 💖

🌈 SEE ALSO 🌈

go read these if you want the full lore, bestie:

• gpio(4)
• gpioctl(8)
• Intel® Atom™ Z8000 Processor Series Vol 1.
• Intel® Atom™ Z8000 Processor Series Vol 2.

🎀 HISTORY 🎀

The chvgpio manual page first appeared in FreeBSD 12. so yes, it's been doing its thing since then. ✨
