🌸 atmel_nor_s...l_protection(9) 🌸

okay so bestie, welcome to the Kernel API Manual — yes that's the whole manual name, we're in kernel land now, put your hair up 💅 this one's a single function and honestly she's cute and to the point.

✨ NAME ✨

atmel_nor_set_global_protection — literally does a Global Protect or Unprotect command. that's it, that's the whole job 🫶

---

🦋 SYNOPSIS 🦋

int atmel_nor_set_global_protection (struct spi_nor *nor , loff_t ofs ,
       u64 len , bool is_protect );

copy it exactly, don't be creative with the signature babes, the compiler will humble you real fast 😭

🎀 ARGUMENTS 🎀

• nor — pointer to struct spi_nor. your main character struct, the whole flash situation lives in here 👑
• ofs — offset in bytes. where we're at, positionally speaking 📍
• len — len in bytes. how much of it we're talking about 📏
• is_protect — if true, do a Global Protect; otherwise it's a Global Unprotect. one bool, two vibes, choose wisely 🧚
