STRUCT REGULATOR_CONFIG(9)

💖 struct regulator_config(9) 💖

okay bestie, welcome to the Kernel API Manual — this is the page for struct regulator_config, and it's lowkey the glow-up page for Dynamic regulator descriptor. yes, that's the NAME. slay.

---

✨ SYNOPSIS ✨

like, here's the whole struct, exactly as it lives, no cap:

struct regulator_config {
    struct device *dev;
    const struct regulator_init_data *init_data;
    void *driver_data;
    struct device_node *of_node;
    struct regmap *regmap;
    struct gpio_desc *ena_gpiod;
 };

she's compact, she's iconic, she's six fields of main character energy. 🎀

🦋 Members 🦋

okay so let's meet the cast, one by one:

• dev — the struct device for the regulator. the home address, the vibe check, the whole identity. 💅
• init_data — platform provided init data, passed through by driver. it's giving "handed down from above," and we respect it. ✨
• driver_data — private regulator data. that's your stuff, bestie, nobody else's business. 🙈
• of_node — OpenFirmware node to parse for device tree bindings (may be NULL). yes, she can be NULL, and that's valid, don't panic. 🌸
• regmap — regmap to use for core regmap helpers if dev_get_regmap is insufficient. the backup plan that absolutely eats. 🔥
• ena_gpiod — GPIO controlling regulator enable. the little on/off switch with big responsibilities. ⭐

---

💜 Description 💜

so the way this works: each regulator registered with the core is described with a structure of this type and a struct regulator_desc. two structs, one destiny, iykyk. 🫶

this structure contains the runtime variable parts of the regulator description — the stuff that changes at runtime while struct regulator_desc handles the rest. lowkey a perfect little division of labour. 💖

🌈 SEE ALSO 🌈

go read these next, bestie, they're all in the kernel file ./include/linux/regulator/driver.h:

• struct regulator_ops(9)
• struct regulator_desc(9)
• struct regulator_err_state(9)
• struct regulator_irq_data(9)
• struct regulator_irq_desc(9)

ok real talk — this page came out of ./include/linux/regulator, it's dated October 2026, and it's part of the Kernel API Manual. mwah, that's the sign-off. periodt. 💋👑
