The unittest dtbs have various intentional errors which cause warnings.
With the latest dtc sync to v1.6.1-19-g0a3a9d3449c8, we need to disable
some new checks: node_name_vs_property_name and interrupt_map warnings.
These warnings are also generated for static_base_1.dtb, so add
DTC_FLAGS for it.
Note that the interrupt_map warnings only appear once interrupt_provider
warning is re-enabled globally.

Thanks for splitting the DTC_FLAGS into per file values.
I dug into the unittest code that uses the dts node that causes the
interrupt map warning and do not see any reason not to fix the dts
so that the warning will not occur, instead of masking it with
the DTC_FLAGS. I just now submitted a patch to fix the .dtsi at
https://lore.kernel.org/all/[email protected]/

That thread ended up deciding that the .dtsi should not be fixed to
avoid the warning (it was a deliberate error to allow a specific test),
so for the [v2] patch that started this thread:

Note this commit in Linus's tree breaks clang-based systems with the
following build errors:
FATAL ERROR: Unrecognized check name "interrupt_map"
FATAL ERROR: Unrecognized check name "node_name_vs_property_name"
Any thoughts about what to do?

I don't think it has anything to do with clang. These messages come
from dtc and there's not any 'test the options are supported'
mechanism for new options. It looks like the dtc update referenced in
Fixes is missing or dtc is stale. There's no error in kernelci[1].

Ah, yes, turns out that Android is building their kernel with an old
version of dtc. So that's the issue here, I'll go work to fix that
up...
Sorry for the noise.
