--- Comment #119 from Lev Popov <leo at nabam.net> ---
Patch works great for my DA200, instruction to apply it on Ubuntu 16.04 without
recompiling the kernel:

$ sudo -i
$ apt-get install linux-source-4.4.0
$ cp -R /usr/src/linux-source-4.4.0/ubuntu/i915 /usr/src/i915_bpo-usbc
$ cd /usr/src/i915_bpo-usbc
$ cat << EOF > dkms.conf 
PACKAGE_NAME="i915_bpo"
PACKAGE_VERSION="usbc"
AUTOINSTALL=yes
REMAKE_INITRD=yes
DEST_MODULE_LOCATION="/updates"
BUILD_EXCLUSIVE_KERNEL="^4.4.*"
EOF
$ sed -i
's#../../drivers/platform/x86/intel_ips.h#../../linux-source-4.4.0/drivers/platform/x86/intel_ips.h#g'
intel_pm.c
$ patch -p5 <
/tmp/drm-i915-Reduce-Data-Link-N-value-for-1-lane-DP--hdmi-converters.patch
$ dkms add -m i915_bpo -v usbc
$ dkms build -m i915_bpo -v usbc
$ dkms install -m i915_bpo -v usbc
$ reboot
