ENUM DPLL_PIN_CAPABILITIES(9)

🌸 enum dpll_pin_capabilities(9) — Kernel API Manual 🌸

okay bestie, gather round, because we're talking about enum dpll_pin_capabilities(9) today and honestly? it's giving "small but mighty" 💅 this is the kernel API manual energy you came for, and this lil enum is the whole vibe 🎀

---

✨ NAME ✨

enum dpll_pin_capabilities — this bad boy is what defines the possible capabilities of a pin, and it's also the set of valid flags you can slap on the DPLL_A_PIN_CAPABILITIES attribute. like, that's literally its whole job and it ate 🔥

---

🦋 SYNOPSIS 🦋

enum dpll_pin_capabilities {
    DPLL_PIN_CAPABILITIES_DIRECTION_CAN_CHANGE ,
    DPLL_PIN_CAPABILITIES_PRIORITY_CAN_CHANGE ,
    DPLL_PIN_CAPABILITIES_STATE_CAN_CHANGE ,
    DPLL_PIN_CAPABILITIES_STATE_CONNECTED_OVERRIDE

};

no cap, that's the whole thing 👑 copy it exactly, don't be out here renaming things, mkay? 🙈

🌈 Constants 🌈

bestie these are the constants and each one is lowkey important, so let's go one by one, no skipping, we don't do that here 🫶

• DPLL_PIN_CAPABILITIES_DIRECTION_CAN_CHANGE — the pin direction can be changed. yep, it's flexible like that ✨
• DPLL_PIN_CAPABILITIES_PRIORITY_CAN_CHANGE — the pin priority can be changed. glow-up enabled 💅
• DPLL_PIN_CAPABILITIES_STATE_CAN_CHANGE — the pin state can be changed. main character energy fr fr ⭐
• DPLL_PIN_CAPABILITIES_STATE_CONNECTED_OVERRIDE — the pin state can be set to connected regardless of the current DPLL device mode, overriding the active input selection. iconic behaviour, but heads up: it requires state-can-change to be set as well — so like, you can't have this one on its own, it needs its bestie 😭

ok but seriously, that last one has a dependency situation — DPLL_PIN_CAPABILITIES_STATE_CONNECTED_OVERRIDE only works if state-can-change is set too. don't forget it, ngl that's the kind of thing that'll ruin your whole afternoon 🫠
