STRUCT PRCM_GPIOCR_ALTCX_PIN_DESC(9)

💅 struct prcm_gpiocr_altcx_pin_desc(9)

okay bestie, welcome to the Kernel API Manual 🎀 — yes we're reading kernel headers for fun now, this is who we are, and honestly? iconic of us. today's main character is struct prcm_gpiocr_altcx_pin_desc, aka Other alternate-C pin. that's literally its NAME, no notes ✨

🌸 SYNOPSIS 🌸

here's the shape of it, copy it exactly bestie, don't freestyle:

struct prcm_gpiocr_altcx_pin_desc {
    unsigned short pin;
    struct prcm_gpiocr_altcx altcx[PRCM_IDX_GPIOCR_ALTC_MAX];
};

like, that's the whole vibe. two fields, zero drama. 🦋

💖 Members 💖

• pin — The pin number. that's it, that's the girl. she's an unsigned short and she knows her number, periodt 💅
• altcx — array of other alternate-C[1-4] functions. yup, an array, sized PRCM_IDX_GPIOCR_ALTC_MAX, holding struct prcm_gpiocr_altcx goodies. four whole alternate-C functions living their best lives in there 🫶 the [1-4] is giving "there are several of these and we're not gonna pretend otherwise" 🔥

ngl bestie if you skip these you're gonna be confused later and i will simply say i told you so 😭💀

and that's the page!! 💜 this little love letter came from the source tree at ./include/linux/gpio, dated October 2026 — yes, future girl summer 🌈 mark your calendars, screenshot the struct, and go slay some pin muxing for me. mwah 🍓🧚‍♀️⭐
