🌸 NAME 🌸

tegra_i2c_writel — safely write to an I2C client controller register 💖

like, the whole vibe is: write it, then double-check it actually landed. iconic behavior honestly.

---

✨ SYNOPSIS ✨

void tegra_i2c_writel (u32 val , void *reg );

---

🎀 ARGUMENTS 🎀

• val — the value to be written 👑 like, the actual thing you're sending in
• reg — the register to write to 🎯 that's the destination, bestie

---

🦋 DESCRIPTION 🦋

so here's the tea ☕: a write to an I2C controller register needs to be read back to make sure that the value has arrived. that's it. that's the whole function's personality. write, then verify. no "trust me bro" energy allowed in this house 💀✨
