ca8210_interrupt_handler(9)

ca8210_interrupt_handler(9) 🎀

okay bestie, this lil page lives in the Kernel API Manual and it's all about ca8210_interrupt_handler — interrupt-handler main character energy only ✨.

🌸 NAME 🌸

ca8210_interrupt_handler — called when an irq is received from the ca8210 💅

🦋 SYNOPSIS 🦋

irqreturn_t ca8210_interrupt_handler (int irq , void *dev_id );

💖 ARGUMENTS 💖

• irq — the id of the irq being handled, literally the interrupt's lil ticket number 🎟️
• dev_id — a pointer passed by the system, pointing to the ca8210's private data 🫶

🔥 DESCRIPTION 🔥

This function is called when the irq line from the ca8210 is asserted — signifying that the ca8210 has a message to send upstream to us 😭. It starts the asynchronous spi read. That's the vibe. Slay.

⭐ RETURN ⭐

It returns an irq return code. periodt 💅
