zynq_gpio_probe(9)

💅 zynq_gpio_probe(9) — like, the Kernel API Manual entry, bestie

okay so this is zynq_gpio_probe, straight out of the Kernel API Manual, and it's genuinely the moment where a zynq_gpio device wakes up and becomes a whole person. main character energy fr fr ✨

🌸 NAME 🌸

zynq_gpio_probe — the Initialization method for a zynq_gpio device 🎀

✨ SYNOPSIS ✨

int zynq_gpio_probe (struct platform_device *pdev );

🦋 ARGUMENTS 🦋

• pdev — the platform device instance. that's the device we're setting up, she's the guest of honour 💖

👑 DESCRIPTION 👑

okay so here's the vibe: this function goes and allocates memory resources for the gpio device, and then it registers all the banks of the device. not one bank, not two — all of them. she's thorough like that 💅

and that's not even it — it also sets up interrupts for the gpio pins 🔥 so the pins can actually yell for attention when something happens.

💀 NOTE 💀

ngl this part matters: interrupts are disabled for all the banks during initialization. so like, don't expect any interrupt action mid-setup, bestie — she's not listening yet 🙈

⭐ RETURN ⭐

• 0 on success 🫶
• negative error otherwise 😭
