ENUM ICVS_RESOURCES(9)

💅 enum icvs_resources(9) — a Kernel API Manual moment

okay so this is a page from the Kernel API Manual, and it's all about enum icvs_resources — literally just a device capability / resource category situation. bestie, it's a whole enum and it's lowkey important, so let's get into it ✨

---

✨ SYNOPSIS ✨

enum icvs_resources {
    ICVS_NOTSUP ,
    ICVS_LIGHTCAP ,
    ICVS_FULLCAP

};

like, that's the whole thing. three constants, no drama 🎀

---

🌸 Constants

• ICVS_NOTSUP — capability not supported / not yet determined. it's giving "we don't know yet, don't ask me" 🙈
• ICVS_LIGHTCAP — light capability (limited GPIO / no dedicated wake IRQ). the budget-friendly version, fr fr.
• ICVS_FULLCAP — full capability (reset GPIO, wake IRQ, extended protocol). the full package, main character energy 👑

---

🦋 Description 🦋

so what this enum actually does: it categorizes hardware resource availability, and that categorization influences protocol features — things like reset control, wake IRQ, and GPIO mediated ownership. iykyk 💅

light capability devices expose a reduced set of control GPIOs. full capability devices? they provide all the optional signals and features. iconic behavior honestly.

and NOTSUP represents an unsupported or uninitialized state — like when the hardware hasn't told you what it is yet, so it's just vibing in the unknown 🌈

go read those too, bestie. the whole CVS family is right there and it's all connected, no cap 💜

that's the whole page! 🫶 cute little sign-off: this came from ./drivers/media/i2c/cvs, and the date on it is October 2026 ⭐ so yeah, timestamps from the future, we love that for us. mwah 💋
