Hi, in order to avoid the if-else in patch 4/10 maybe we can do:

```
struct interrupt_to_isr {
	char* name;
	irqreturn_t isr(int irq, void *ctx);
}

interrupt_to_is px30_isrs[] {
	{"isp", rkisp1_isp_isr}
	{"mi",  rkisp1_capture_isr}
	{"mipi", rkisp1_mipi_isr}
}
static const struct rkisp1_match_data px30_isp_match_data = {
	.clks = px30_isp_clks,
	.size = ARRAY_SIZE(px30_isp_clks),
	.isp_ver = RKISP1_V12,
	.isrs = px30_isrs
};
//and similar for rk3399
```

Then in the probe we just do
```
for each (name,isr) in isrs
	irq = platform_get_irq_byname(name)
	devm_request_irq(dev, irq, isr,...
```


Thanks,
