C++ (Cpp) sys_irq_enable Examples

Example #1

static unsigned int sys_irq_startup(struct irq_data *d)
{  
// 	unsigned long chip_id;
//	unsigned long tmp_u32;

#if 0	
	tmp_u32 = *(volatile unsigned long*)0xB8000000;
	chip_id = tmp_u32 >> 16;	
	if (chip_id == 0x3602)	// 3603 interrupt polarity is ok, do nothing
	{
		if (irq >= 40) {
			*(u32 *)(0xB800002C) |= (u32)(1<<(irq - 32 - sys_irq_base));	/* Set polarity */
		}
		else {
