pmaports/device/linux-lg-lenok/APKBUILD

# APKBUILD based on linux-vanilla aport. Changes:
# - disabled module installation
# - add !check !tracedeps
# - package: just install zimage and kernel.release, because the kernel config
#	does not generate modules or dtb files
# - do not create -dev subpackage (makes no sense without module support)
#
# Changes:
# - enable devtmpfs (needed for udev -> touch support in weston)
# - enabled CONFIG_VT (needed for weston to work)
# - Added ata2001's refresh rate fix for 60hz (otherwise screen is stuck at 15hz)
# - Enable generation of dtb
