st_i2c_wr_fill_tx_fifo(9)

✨ NAME ✨

okay bestie, welcome to the Kernel API Manual page for st_i2c_wr_fill_tx_fifo(9) — short name, big “fill the FIFO” energy 💖

st_i2c_wr_fill_tx_fifo — Fill the Tx FIFO in write mode 🎀

---

🌸 SYNOPSIS 🌸

void st_i2c_wr_fill_tx_fifo (struct st_i2c_dev *i2c_dev );

---

🦋 ARGUMENTS 🦋

• i2c_dev — the Controller's private data, aka the controller’s own little backstage pass stash 💅

---

💖 DESCRIPTION 💖

okay so picture this: we’re in write mode, and this function literally fills the Tx FIFO with the I2C transfer buffer. That’s the whole vibe — Tx FIFO gets filled, write mode gets handled, and the kernel keeps it moving ✨

it’s giving “teamwork makes the dream work” but for I2C transfers, fr fr 🫶
