STRUCT S3C2410_PLATFORM_I2C(9)

✨ struct s3c2410_platform_i2c(9) ✨

okay bestie, so this is a page straight out of the Kernel API Manual, and today's main character is struct s3c2410_platform_i2c — yes that's a mouthful, yes we're gonna get through it together 🫶

---

🌸 NAME 🌸

struct s3c2410_platform_i2c — literally just the platform data for s3c I2C. that's the vibe. that's the whole assignment 💅

---

🎀 SYNOPSIS 🎀

here's the shape of it, bestie — copy it exactly, no cap:

struct s3c2410_platform_i2c {
    int bus_num;
    unsigned int    flags;
    unsigned int    slave_addr;
    unsigned long   frequency;
    unsigned int    sda_delay;
    void (*cfg_gpio)(struct platform_device *dev);
 };

---

🦋 Members 🦋

okay so let's meet the cast, one by one, they're all icons in their own way:

• bus_num — the bus number to use (if possible). like, if possible, okay? don't come for her if she can't 🫠
• flags — any flags for the I2C bus (e.g. S3C_IICFLK_FILTER). little toggles, little settings, very demure.
• slave_addr — the I2C address for the slave device (if enabled). only shows up when she's enabled, which is so valid of her ✨
• frequency — the desired frequency in Hz of the bus. and listen — this is guaranteed to not be exceeded, so it's a ceiling, not a suggestion 🔥 if the caller does not care, use zero and the driver will select a useful default. zero = "idk you pick", and honestly? same energy.
• sda_delay — the delay (in ns) applied to SDA edges. nanoseconds, bestie. we are out here measuring vibes in nanoseconds 💀
• cfg_gpio — a callback to configure the pins for I2C operation. it takes a struct platform_device *dev, and it's the one that actually goes and sets up the pins. main character energy fr fr 👑
