✨ zynq_gpio_set_irq_type(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one lives in section 9 and it's literally called zynq_gpio_set_irq_type — the whole vibe is setting the irq type for a gpio pin 🎀

🌸 NAME 🌸

zynq_gpio_set_irq_type — Set the irq type for a gpio pin 💅

🦋 SYNOPSIS 🦋

int zynq_gpio_set_irq_type (struct irq_data *irq_data , unsigned int
type );

so it takes a struct irq_data * and an unsigned int and hands you back an int, no cap ✨

🎀 ARGUMENTS 🎀

  • irq_data — the irq data containing the irq number of the gpio pin. like, it's giving "which pin are we even talking about" energy 🙈
  • type — the interrupt type that is to be set for that gpio pin. this is the main character of the whole function tbh 👑

💜 DESCRIPTION 💜

Bestie, here's the tea 🍓 this function gets the gpio pin number and its bank from the gpio pin number, and then it configures the INT_TYPE, INT_POLARITY and INT_ANY registers. that's it, that's the whole glow-up 🔥

⭐ RETURN ⭐

Returns 0, or a negative error otherwise. and now the receipts, because the mapping is very much specific 🧚

  • TYPE-EDGE_RISING → INT_TYPE - 1, INT_POLARITY - 1, INT_ANY - 0
  • TYPE-EDGE_FALLING → INT_TYPE - 1, INT_POLARITY - 0, INT_ANY - 0
  • TYPE-EDGE_BOTH → INT_TYPE - 1, INT_POLARITY - NA, INT_ANY - 1
  • TYPE-LEVEL_HIGH → INT_TYPE - 0, INT_POLARITY - 1, INT_ANY - NA
  • TYPE-LEVEL_LOW → INT_TYPE - 0, INT_POLARITY - 0, INT_ANY - NA

like, please don't mix these up, the hardware will simply not slay 💀

k that's the whole page, go read the source in ./drivers/gpio if you wanna fact-check me, iykyk 👀

mwah, bye bestie — this one's filed under ./drivers/gpio, dated October 2026, and it's page zynq_gpio_set_irq_type(9) of the Kernel API Manual. periodt. 💅✨
