STRUCT RMI_I2C_XPORT(9)

💅 struct rmi_i2c_xport(9)

okay so bestie, welcome to the Kernel API Manual — this is the page for struct rmi_i2c_xport, and no cap, it's literally the little info-holder for i2c communication 🦋

✨ NAME ✨

struct rmi_i2c_xport — stores information for i2c communication

---

🎀 SYNOPSIS 🎀

struct rmi_i2c_xport {
    struct rmi_transport_dev xport;
    struct i2c_client *client;
    struct mutex page_mutex;
    int page;
    u8 *tx_buf;
    size_t tx_buf_size;
    struct regulator_bulk_data supplies[2];
    u32 startup_delay;
 };

like, that's the whole shape of it, copy it exactly please 💖

👑 Members 👑

• xport — the transport interface structure. she's the main character of this struct ngl 💫
• client — the I2C client device structure. the actual device bestie 🫶
• page_mutex — locks the current page so nobody goes changing pages in unexpected ways 😭 fr fr, it's giving bodyguard energy
• page — keeps track of the current virtual page, lowkey the bookmark of the whole situation 🎀
• tx_buf — buffer used for transmitting data to the sensor over i2c. her job is sending the vibes ✨
• tx_buf_size — size of the buffer. yes, that buffer. the one right above 💅
• supplies — array of voltage regulators. plural, iconic, and yes it's an array 🔥
• startup_delay — milliseconds to pause after powering up the regulators. like a little beauty rest after the regulators wake up ⭐

💀 quick vibe check: these are the exact members from the page, so don't go renaming anything, bestie — the compiler will NOT be nice about it 🙈

and that's the whole page! this cutie came from ./drivers/input/rmi4, dated October 2026, and it's struct rmi_i2c_xport(9) — slay, periodt, go forth and i2c responsibly 🧚💜
