✨ ezport_flash(9) ✨

okay so this is from the Kernel API Manual and honestly? it's giving "tiny function, big responsibility" 🫶 we're flashing firmware onto a device through an NXP EzPort interface, and yeah, it's exactly as cool as it sounds. bestie, let's get into it 💅

🎀 NAME 🎀

ezport_flash — flash device firmware ✨

Literally what it says on the tin: it flashes firmware. Onto a device. Through EzPort. slay.

---

🌸 SYNOPSIS 🌸

int ezport_flash (struct spi_device *spi , struct gpio_desc *reset ,
       const char *fwname );

Three args, one int back. no cap, that's the whole vibe check 🔥

---

🦋 ARGUMENTS 🦋

• spi — the SPI device for the NXP EzPort interface. this is your main character, the whole reason we're here 👑
• reset — the gpio connected to the device reset pin. gotta be able to poke the reset, iykyk 🎀
• fwname — filename of the firmware that should be flashed. yes babe, the actual firmware, the whole point 💖

💜 CONTEXT 💜

can sleep 😴

(that's it. that's the context. it can sleep, so plan accordingly, don't be calling it from somewhere spicy 🌶️)

---

⭐ RETURN ⭐

0 on success; negative errno on failure 🙂

so like — zero means we ate, negative errno means something went sideways and you should go read the errno, fr fr 🙈
