✨ bq25792_hw_init(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's the bq25792_hw_init page and it's literally the glow-up routine for your BQ25792 charger chip. no cap. let's get into it 🫶

---

🌸 NAME 🌸

bq25792_hw_init — Initialize BQ25792 hardware

---

🎀 SYNOPSIS 🎀

int bq25792_hw_init (struct bq257xx_chg *pdata );

---

🦋 ARGUMENTS 🦋

• pdata — the driver platform data. that's the whole vibe check right there, one (1) pointer and it's carrying all the platform info 🫡

---

💖 DESCRIPTION 💖

so what this function does is initialize the BQ25792, and it does it in a very specific order, okay, pay attention:

• disabling the watchdog — bye bye watchdog 👋
• enabling discharge current sensing with a 5A limit — 5A, exactly 5A, don't @ me
• configuring input current regulation — regulating that input current, iconic behavior

then it sets these from platform data, like it's ordering off a menu:

• the charge current
• charge voltage
• minimum system voltage
• input current limit

and finally it enables and configures the ADC to measure all available channels — every single channel, no skipping, main character ADC energy ✨

---

🔥 RETURN 🔥

Returns 0 on success or an error code on error 😭 so like, check it. fr fr.
