# This is seperate from linux-edge so we can control the release cycle better.
# If this kernel is updated and fails to boot it's quite hard to recover the
# rk3399 devices due to the boot order. This kernel also has a kconfig that has
# more modules built-in that are required for successfully booting on these
# devices.

# It's important that CONFIG_ROCKCHIP_CDN_DP is _disabled_ because it causes
# boot failure
