✨ i2c_of_probe_simple_enable ✨

okay so bestie, this is a page from the Kernel API Manual and it's about i2c_of_probe_simple_enable — literally the simple helper that lets the I2C OF prober get and enable its resources 💅 it's giving "little function, big job" and honestly? obsessed.

---

🎀 SYNOPSIS 🎀

int i2c_of_probe_simple_enable (struct device *dev , struct device_node
*bus_node , void *data );

three args, returns an int, no cap 🫶

---

🌸 ARGUMENTS 🌸

• dev — a pointer to the struct device of whoever's calling. lowkey it's only there for dev_printk messages, so it's the group-chat narrator and nothing else 💬
• bus_node — a pointer to the struct device_node of the I2C adapter. that's the vibe check on which adapter we're talking about 🌈
• data — a pointer to the struct i2c_of_probe_simple_ctx helper context. the main character carrying all the info ✨

---

💖 DESCRIPTION 💖

so here's the tea, fr fr:

• if i2c_of_probe_simple_opts->supply_name is given, it requests the regulator supply with that name 🔌
• if i2c_of_probe_simple_opts->gpio_name is given, it requests the GPIO with that name. or, if it's the empty string, it requests the unnamed GPIO 🧚
• if a regulator supply was actually found, it enables that regulator ⚡
• if a GPIO line was found, it configures the GPIO line to output and sets the value according to the given options 🎀

it's literally "find the thing, then turn the thing on" energy and she ate 🔥

⭐ RETURN ⭐

0 on success or no-op (yes bestie, doing nothing counts as a win sometimes 😌), or a negative error number on failure 💀
