Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

# Apply overlays statically with fdtoverlay.  This is a build time test that
# the overlays can be applied successfully by fdtoverlay.  This does not
# guarantee that the overlays can be applied successfully at run time by
# unittest, but it provides a bit of build time test coverage for those
# who do not execute unittest.
#
# The overlays are applied on top of static_base_1.dtb and static_base_2.dtb to
# create static_test_1.dtb and static_test_2.dtb.  If fdtoverlay detects an
# error than the kernel build will fail.  static_test_1.dtb and
# static_test_2.dtb are not consumed by unittest.
#
# Some unittest overlays deliberately contain errors that unittest checks for.
# These overlays will cause fdtoverlay to fail, and are thus not included
# in the static test:
#			  overlay_bad_add_dup_node.dtbo \
#			  overlay_bad_add_dup_prop.dtbo \
#			  overlay_bad_phandle.dtbo \
#			  overlay_bad_symbol.dtbo \
