🫶 DESCRIPTION 🫶

This function lets you override the default I2C bus speed for a given I2C bus with a command line option. it’s giving “custom vibes only” ✨

The format is literally:

i2c_bus=bus_id,clkrate (in kHz)

So yeah: bus_id, then clkrate, and the clock rate is in kHz. don’t forget that part, iykyk 😭

Returns 1 on success, 0 otherwise. that’s the whole vibe check: 1 = slay, 0 = not slay 💀
