bcm63xx_udc_probe(9)

hiii bestie 💖 welcome to the Kernel API Manual page for bcm63xx_udc_probe(9) — the function that initializes a new instance of the UDC. We’re keeping every detail, no cap. 🫶

🌸 NAME 🌸

bcm63xx_udc_probe — initialize a new instance of the UDC. That’s the assignment, and it ate. ✨

✨ SYNOPSIS ✨

int bcm63xx_udc_probe (struct platform_device *pdev );

🎀 ARGUMENTS 🎀

• pdev — the platform device struct from the bcm63xx BSP code. It’s literally the main character input here. 🦋

💅 DESCRIPTION 💅

okay so listen: platform data is required here — not optional, not a suggestion. Why? Because pd.port_no varies from chip to chip, and it’s used to switch the correct USB port to device mode. That’s the whole reason the platform data has to show up. periodt. 🔥

bestie, do not skip the platform data. The pd.port_no value is doing the port-picking, and it changes across chips. 💀
