STRUCT XIIC_I2C_PLATFORM_DATA(9)

💖 struct xiic_i2c_platform_data 💖

okay bestie, welcome to the Kernel API Manual ✨ we're talking about struct xiic_i2c_platform_data, which is literally the platform data of the Xilinx I2C driver. yeah. that one. 🦋

---

🌸 NAME 🌸

struct xiic_i2c_platform_data — Platform data of the Xilinx I2C driver 🎀

---

✨ SYNOPSIS ✨

the whole vibe, in code:

struct xiic_i2c_platform_data {
    u8 num_devices;
    struct i2c_board_info const     *devices;
 };

two fields. that's it. iconic minimalism 💅

• num_devices — Number of devices that shall be added when the driver is probed. like, how many besties are we bringing to the bus 🫂
• devices — The actuall devices to add. yes bestie, the actual devices themselves, the real ones, no fake ones 🎀

---

💜 Description 💜

so the whole purpose of this platform data struct is to be able to provide a number of devices that should be added to the I2C bus. and the reason?? 😭 sometimes the I2C board info is just not enough. like, a new PCI board can for instance be plugged into a standard PC, and the bus number might be unknown at early init time. so you can't just rely on the board info alone — you gotta hand it the list. it's giving "trust me, I brought my own guest list" ✨
