STRUCT STM32F7_I2C_SETUP(9)

💜 struct stm32f7_i2c_setup(9) 💜

okay so bestie, welcome to the Kernel API Manual — this is the page for struct stm32f7_i2c_setup, and it's literally the little private stash of I2C timing setup params. private as in "for the driver's eyes only", not "weird", okay? 🎀

✨ NAME ✨

struct stm32f7_i2c_setup — private I2C timing setup parameters 💅

---

🌸 SYNOPSIS 🌸

here's the whole struct, no cap, every field exactly where it lives:

struct stm32f7_i2c_setup {
    u32 speed_freq;
    u32 clock_src;
    u32 rise_time;
    u32 fall_time;
    u32 fmp_clr_offset;
    bool single_it_line;
    bool fmp_cr1_bit;
 };

---

🦋 Members 🦋

time for the vibe check on every single field, one by one, because none of them are getting skipped:

• speed_freq — the I2C speed frequency, measured in Hz. this is the "how fast are we going" number 🏎️
• clock_src — the I2C clock source frequency, also in Hz. the source of truth for the clock, iykyk ⏰
• rise_time — rise time, in ns. yes, nanoseconds, we're being precise 💫
• fall_time — fall time, in ns. same energy, opposite direction 🌈
• fmp_clr_offset — the Fast Mode Plus clear register offset, measured from the set register. it's giving "where's the clear one relative to the set one" energy 🔥
• single_it_line — when this is set, only a single IT line is used for both events/errors. one line carrying everything, main character energy fr fr 👑
• fmp_cr1_bit — Fast Mode Plus control is done via a bit in CR1 instead. a whole bit, doing the whole job 🙈
