🌸 NAME 🌸

stm32_bsec_optee_ta_read — nvmem read access using TA client driver 💖

Okay bestie, this is the function that does an nvmem read through the TA client driver. It’s giving “read energy” and it’s literally sitting in the Kernel API Manual. 🫶

🎀 SYNOPSIS 🎀

int stm32_bsec_optee_ta_read (struct tee_context *ctx , unsigned int
       offset , void *buf , size_t bytes );

---

💅 ARGUMENTS 💅

• ctx — the OP-TEE context provided by stm32_bsec_optee_ta_open. That’s the handshake, bestie. 🤝
• offset — nvmem offset.
• buf — buffer to fill with nvem values. Not me noticing the manpage says nvem and not nvmem — keeping it exactly as written, periodt. 🙈
• bytes — number of bytes to read.

---

🔥 RETURN 🔥

On success, 0. On failure, -errno. No cap. 💀

---

🦋 SEE ALSO 🦋

• Kernel file ./drivers/nvmem/stm32-bsec-optee-ta.h — the header bestie, go look. 📂
