ti_sci_cmd_set_irq(9)

✨ NAME ✨

okay so ti_sci_cmd_set_irq(9) is from the Kernel API Manual, and the way that this one just configures a host irq route between the requested source and destination is honestly iconic. That's the whole assignment: source + destination in, IRQ route configured. slay. 💅

🌸 SYNOPSIS 🌸

int ti_sci_cmd_set_irq (const struct ti_sci_handle *handle , u16 src_id
       , u16 src_index , u16 dst_id , u16 dst_host_irq );

🎀 ARGUMENTS 🎀

• handle — pointer to the TISCI handle, bestie. 🫶
• src_id — device ID of the IRQ source.
• src_index — IRQ source index within the source device.
• dst_id — device ID of the IRQ destination.
• dst_host_irq — IRQ number of the destination device.

💖 RETURN 💖

0 if all went fine, else return appropriate error. No cap: zero is the happy path; anything else means you get the appropriate error back. 😭
