omap4_vc_i2c_timing_init(9)

💅 omap4_vc_i2c_timing_init — like, the Kernel API Manual page for it, bestie ✨

okay so this is a page from the Kernel API Manual (yes that's the manual name, we're folding it in, you're welcome 🎀) and it's all about omap4_vc_i2c_timing_init, which sets up board I2C timing parameters. iconic behavior honestly.

✨ NAME ✨

omap4_vc_i2c_timing_init — sets up board I2C timing parameters 🦋

---

🌸 SYNOPSIS 🌸

void omap4_vc_i2c_timing_init (struct voltagedomain *voltdm );

like literally that's the whole signature. no cap.

---

💖 ARGUMENTS 💖

• voltdm — a voltagedomain pointer, and its whole job is to get data from. that's it. that's the vibe. it's giving "middle management" but in a cute way 🫶

---

👑 DESCRIPTION 👑

so here's the tea ☕: this function uses the settings that PMIC + board supply to calculate the total I2C channel capacitance, and then it sets the timing parameters based on that. slay.

and like… the values it wants are pre-calculated and handed to you in data tables, because ngl it's not too straightforward to calculate these at runtime. so we're not doing that. we're using the table. periodt 💅

okay so before you go 🎀: this whole thing lives in ./arch/arm/mach-omap2, it's dated October 2026, and it ships as part of the Kernel API Manual (that's the source/version energy). consider yourself signed off with a kiss 💋 mwah, go set up those I2C timings, you're gonna ate 🍓✨
