of_register_spi_devices(9)

🦋 of_register_spi_devices(9) 🦋

okay so this is literally the Kernel API Manual page for of_register_spi_devices(9), and yes bestie, we're about to make kernel SPI registration make sense. 💅✨

---

🌸 NAME 🌸

of_register_spi_devices — Register child devices onto the SPI bus 🎀

---

✨ SYNOPSIS ✨

void of_register_spi_devices (struct spi_controller *ctlr );

---

🎀 ARGUMENTS 🎀

• ctlr — Pointer to spi_controller device. that's the whole argument, no cap 🫶

---

💅 DESCRIPTION 💅

So the vibe is: this function registers an spi_device for each child node of the controller node which represents a valid SPI target device. 🌈

Like, every valid SPI target child node gets its own spi_device registered. iconic behavior, honestly. 👑
