s3c_gpio_setpull(9)

💅 s3c_gpio_setpull

okay so this one is a Kernel API Manual page, bestie, and it's all about one tiny but iconic little function. no cap, it's short — so let's get into it 🫶

---

✨ NAME ✨

s3c_gpio_setpull — sets the state of a gpio pin pull resistor, literally that's the whole gig 💫

---

🌸 SYNOPSIS 🌸

int s3c_gpio_setpull (unsigned int pin , samsung_gpio_pull_t pull );

like look at her. pristine. not a single character out of place 🎀

---

🦋 ARGUMENTS 🦋

• pin — the pin number you wanna configure the pull resistor on. that's the one you're pulling up on, bestie 👑
• pull — the actual configuration for the pull resistor. this is the vibe you're assigning ✨

---

💖 DESCRIPTION 💖

so what does she do? this function sets the state of the pull-{up,down} resistor for the specified pin. that's it, that's the job, and she does it well 💅

return value tea: it returns 0 if successful 🥳 — or a negative error code if the pin cannot support the requested pull setting 😭 (yes, some pins are picky, we don't judge them for it).

and pull? it's one of these three, periodt:

• S3C_GPIO_PULL_NONE
• S3C_GPIO_PULL_DOWN
• S3C_GPIO_PULL_UP

no in-between, no "it's complicated," just pick one of the three and slay 🌈

and that's the page!! source/version cute little sign-off moment: this iconic piece of documentation lives under ./arch/arm/mach-s3c, dated October 2026, and it's filed as s3c_gpio_setpull(9) 💜 mwah, go set some pull resistors bestie 🧚‍♀️
