From: Rajendra Nayak <redacted> On DRA7 compatible IRQ crossbar, IRQ 10 default mapped to L3_APP_IRQ, IRQ133 is default mapped to NMI pin, 139 and 140 crossbars are unused(not routed). Mark these as unused crossbar IRQs. Technical Reference Manual documentation update expected DRA72x-TRMINC00067 is being used to track the update.

see my earlier comment regarding a potential dts property. thx, Jason.
static struct crossbar_data cb_dra_data = { dra_irqs_unused,
