Due to the presence of the fastboot micro cable in the CI farm,
it causes the hardware to remain in gadget mode instead of host mode.
So it doesn't find the network, which results in failure to mount root
fs via NFS.
Add an overlay dtso file that sets the dr_mode to host, allowing the
USB controllers to work in host mode. With commit 15d16d6dadf6
("kbuild: Add generic rule to apply fdtoverlay"), overlay target can
be used to simplify the build of DTB overlays. It uses fdtoverlay to
merge base device tree with the overlay dtso. apq8016-sbc-usb-host.dtb
file can be used by drm-ci, mesa-ci.

Apologies. I think the second time also the patch was ignored.
Will use

Due to the presence of the fastboot micro cable in the CI farm,
it causes the hardware to remain in gadget mode instead of host mode.
So it doesn't find the network, which results in failure to mount root
fs via NFS.
Add an overlay dtso file that sets the dr_mode to host, allowing the
USB controllers to work in host mode. With commit 15d16d6dadf6
("kbuild: Add generic rule to apply fdtoverlay"), overlay target can
be used to simplify the build of DTB overlays. It uses fdtoverlay to
merge base device tree with the overlay dtso. apq8016-sbc-usb-host.dtb

Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC (and consider --no-git-fallback argument). It might
happen, that command when run on an older kernel, gives you outdated
entries. Therefore please be sure you base your patches on recent Linux
kernel.
You skipped all maintainers, so this patch will be simply ignored.
Best regards,

Due to the presence of the fastboot micro cable in the CI farm,
it causes the hardware to remain in gadget mode instead of host mode.
So it doesn't find the network, which results in failure to mount root
fs via NFS.
Add an overlay dtso file that sets the dr_mode to host, allowing the
USB controllers to work in host mode. With commit 15d16d6dadf6
("kbuild: Add generic rule to apply fdtoverlay"), overlay target can
be used to simplify the build of DTB overlays. It uses fdtoverlay to
merge base device tree with the overlay dtso. apq8016-sbc-usb-host.dtb
file can be used by drm-ci, mesa-ci.
