ads131m_hw_init(9)

💅 ads131m_hw_init — it's in the Kernel API Manual (section 9), bestie

okay so real talk, this one is literally the "wake the ADC up" function. ads131m_hw_init is here to Initialize the ADC hardware, and honestly? iconic behavior. Let's get into it ✨

---

🌸 SYNOPSIS 🌸

int ads131m_hw_init (struct ads131m_priv *priv , struct reset_control
*rstc , bool is_xtal );

like, she takes three things and gives you back an int. that's the whole vibe check 🫶

---

🎀 ARGUMENTS 🎀

• priv — the device private data structure. it's giving "main character energy", everything lives in here 💖
• rstc — optional reset control, or NULL for software reset. so like, you can pass one, but you don't have to — NULL is totally valid and means "do it in software" 🦋
• is_xtal — true if 'clock-names' is "xtal", false if it's "clkin". yes bestie, the name has to match exactly, no cap 🔥

---

⭐ RETURN ⭐

0 on success, or a negative error code 😭 so like, check it. always check it. if it's negative, something went sideways and you need to handle it, fr fr.
