devm_gpio_regmap_register(9)

💖 devm_gpio_regmap_register(9) 💖

okay so welcome to the Kernel API Manual, bestie — we're talking about devm_gpio_regmap_register(9) today and it's literally the resource-managed version of gpio_regmap_register(). slay.

---

✨ NAME ✨

devm_gpio_regmap_register — it's the resource-managed glow-up of gpio_regmap_register(), periodt.

---

🎀 SYNOPSIS 🎀

struct gpio_regmap * devm_gpio_regmap_register (struct device *dev ,
const struct gpio_regmap_config *config );

---

🦋 ARGUMENTS 🦋

• dev — the device that is registering this GPIO device. it's giving "main character device energy" 💅
• config — the configuration for gpio_regmap. yes bestie, this is where the setup lives 🎀

---

🌸 DESCRIPTION 🌸

so this is the managed gpio_regmap_register. for a generic regmap GPIO device registered by this function, gpio_regmap_unregister is automatically called on driver detach. no cap — the cleanup is handled for you, automatic style. ✨

if you want more info, go see gpio_regmap_register — it's the non-managed sibling and it has the details. 🫶

---

🔥 RETURN 🔥

it returns a pointer to the registered gpio_regmap — iconic — or an ERR_PTR error value if things go sideways. 😭
