Is there support for the platform_get_irq_byname() function on ACPI systems?
I'm working on adding ACPI support for a driver that currently only
supports device tree. This driver has code like this:
ret = platform_get_irq_byname(pdev, "core0_irq");
This function works fine on device tree, but it fails on our ACPI system
because our ACPI nodes don't appear to have any way to attach a name to
an IRQ resource:
Method (_CRS, 0x0, Serialized) {
Name (RBUF, ResourceTemplate() {
[snip]
Interrupt (ResourceConsumer, Level, ActiveHigh,
Exclusive, , , )
{0x120, 0x121, 0x122, 0x123}
})
Return (RBUF)
}
I would hate to have to do something like this:
ret = platform_get_irq_byname(pdev, "core0_irq");
if (ret)
/* ACPI doesn't support named resources */
ret = platform_get_irq(pdev, 0);
