💅 mmc_gpiod_set_cd_config(9) ✨

okay so bestie, welcome to the Kernel API Manual 🎀 — this page is all about mmc_gpiod_set_cd_config, and honestly? she's a tiny little function with main character energy. let's get into it 🫶

✨ NAME ✨

mmc_gpiod_set_cd_config — set config for card-detection GPIO 💳🔍

🌸 SYNOPSIS 🌸

int mmc_gpiod_set_cd_config (struct mmc_host *host , unsigned long
config );

💖 ARGUMENTS 💖

• host — the mmc host, aka the main character of this whole operation 👑
• config — a Generic pinconf config (the kind that comes from pinconf_to_config_packed) 🎁

🦋 DESCRIPTION 🦋

so basically, mmc host drivers can use this to fixup a card-detection GPIO's config — like, for example, setting PIN_CONFIG_BIAS_PULL_UP 😌 — but only after they've acquired the GPIO descriptor through mmc_gpiod_request_cd. order matters, babe, it's giving sequencing 💅

⭐ RETURN ⭐

0 on success, or a negative errno value on error 😭 (bestie if it's negative, something went wrong, no cap)
