I have problem in requesting a irq for s32v, I don't konw the first parameter in s32v should be, for example I want to set the PA0 port to be a irq function, and I user the following code:
volatile struct SIUL2_tag *Siul2_Reg = NULL;
Siul2_Reg = ioremap((uintptr_t)&SIUL2, sizeof(struct SIUL2_tag));
Siul2_Reg->MSCR.B.MUX_MODE = 2; // interrupt mux mode selected
// PA0 (the pad is )
ret = request_irq(???, PA0_interrupt_handle, IRQF_TRIGGER_FALLING, "PA0_IRQ", NULL);
the "???" should be? could you tell me how to fill it in a simple case.
Look forward to your answer , thank you very much!
