DWIIC(4)

🌸 NAME 🌸

okay so bestie, this is dwiic — the Synopsys DesignWare I2C controller driver, and it's in section 4 of the Kernel Interfaces Manual, iykyk 💅

---

✨ SYNOPSIS ✨

here's the whole "who attaches to what" situation, no cap:

dwiic* at acpi?
dwiic* at fdt?
dwiic* at pci?
iic* at dwiic?

like, dwiic* can show up hanging off acpi?, off fdt?, or off pci?, and then iic* rides on top of dwiic? 🦋

💖 DESCRIPTION 💖

so the dwiic driver is the main character for the Synopsys DesignWare I2C controller, and it exists so it can plug into the iic(4) framework. that's the whole vibe — it's giving "team player" energy fr fr 🫶

and here's the tea on systems using the Intel OnChip System Fabric: dwiic may need the iosf(4) driver to coordinate access to the I2C bus. so like, sometimes it needs a buddy to keep things from getting messy 👑 lowkey important.
