Hi Rob, Thanks for the review.

Does make W=1 ARCH=powerpc wiiu_defconfig dtbs_check seem reasonable? I ran it, and saw LINT/CHKDT/UPD/SCHEMA/COPY steps, but if I put garbage in the .dts it gives no warnings. >> >> Signed-off-by: Ash Logan <ash@heyquark.com> >> Co-developed-by: Roberto Van Eeden <rw-r-r-0644@protonmail.com> >> Signed-off-by: Roberto Van Eeden <rw-r-r-0644@protonmail.com> >> Co-developed-by: Emmanuel Gil Peyrot <linkmauve@linkmauve.fr> >> Signed-off-by: Emmanuel Gil Peyrot <linkmauve@linkmauve.fr> >> --- >> arch/powerpc/boot/dts/wiiu.dts | 327 +++++++++++++++++++++++++++++++++ >> 1 file changed, 327 insertions(+) >> create mode 100644 arch/powerpc/boot/dts/wiiu.dts >> >> diff --git a/arch/powerpc/boot/dts/wiiu.dts b/arch/powerpc/boot/dts/wiiu.dts >> new file mode 100644 >> index 000000000000..aaf264963f61 >> --- /dev/null >> +++ b/arch/powerpc/boot/dts/wiiu.dts >> @@ -0,0 +1,327 @@ >> +// SPDX-License-Identifier: GPL-2.0 > > What about non-GPL environments?
