via1_irq is remapped to IRQ_AUTO_6 on OSS.
According to via_register_interrupts(), it requests both:
if (via_alt_mapping) {
if (request_irq(IRQ_AUTO_1, via1_irq, 0, "software",
(void *)via1))
pr_err("Couldn't register %s interrupt\n", "software");
if (request_irq(IRQ_AUTO_6, via1_irq, 0, "via1", (void *)via1))
pr_err("Couldn't register %s interrupt\n", "via1");
} else {
if (request_irq(IRQ_AUTO_1, via1_irq, 0, "via1", (void *)via1))
pr_err("Couldn't register %s interrupt\n", "via1");
}
Hence IRQ_AUTO_1 must be shared, and we cannot use an optimized chain
handler for via1_irq() nor iop_ism_irq(). This is the only remaining conflict
I see.
