Some spi flash memories have an interrupt signal which can be used for

Add binding for "interrupts" property so that boards wiring this signal
may describe the connection.

BTW, I don't see any support in SPI NOR for handling these interrupts.
Do you plan to add them in a later patchset?
No current plans, I have little knowledge how spi-nor works in the kernel.
If not, what do you get by
describing them?
Foremost I get to submit a correct device-tree (describes hardware)
to the kernel, without maintainers getting all over me for introducing
new dtbs_check errors.
And I really do prefer submitting a complete device-tree so that all
knowledge I have gained reading private schematics is readily
available the next time someone works on it.

Changes in v7:
- split out of original patchset because it should go via mtd tree
- collected acked-by Rob Herring from v6
- Link to v6: https://lore.kernel.org/r/20240212-add-am64-som-v6-0-b59edb2bc8c3@xxxxxxxxxxxxx
