STRUCT RK3X_I2C_CALCED_TIMINGS(9)

💅 NAME 💅

struct rk3x_i2c_calced_timings — the calculated V1 timings, bestie ✨

Ok so real talk, this is a page straight out of the Kernel API Manual, and it's all about one lil struct that holds the timing numbers the driver crunched for you. Slay.

🌸 SYNOPSIS 🌸

struct rk3x_i2c_calced_timings {
    unsigned long div_low;
    unsigned long div_high;
    unsigned int tuning;
 };

Like, that's the whole vibe. Three fields, no drama. 🫶

🎀 Members 🎀

• div_low — the divider output for low, periodt. Lowkey does exactly what it says on the tin 💅
• div_high — the divider output for high. Twin of the one above, just living its high life ✨
• tuning — okay this one's the main character 👑 it's used to adjust the setup/hold data time, the setup/hold start time, and the setup stop time for v1's calc_timings. And listen — for old hardware, like anyone using v0's calc_timings, this tuning should all be 0. No cap. Don't be out here putting non-zero values in there on v0 hardware, that's not the move 🙈
