Without the DP helper code, the newly added displayport support
causes a link failure:
x86_64-linux-ld: drivers/gpu/drm/hisilicon/hibmc/dp/dp_aux.o: in function `hibmc_dp_aux_init':
dp_aux.c:(.text+0x37e): undefined reference to `drm_dp_aux_init'
x86_64-linux-ld: drivers/gpu/drm/hisilicon/hibmc/dp/dp_link.o: in function `hibmc_dp_link_set_pattern':
dp_link.c:(.text+0xae): undefined reference to `drm_dp_dpcd_write'
x86_64-linux-ld: drivers/gpu/drm/hisilicon/hibmc/dp/dp_link.o: in function `hibmc_dp_link_get_adjust_train':
dp_link.c:(.text+0x121): undefined reference to `drm_dp_get_adjust_request_voltage'
x86_64-linux-ld: dp_link.c:(.text+0x12e): undefined reference to `drm_dp_get_adjust_request_pre_emphasis'

x86_64-linux-ld: dp_link.c:(.text+0x2e3): undefined reference to `drm_dp_dpcd_write'
Add both DRM_DISPLAY_DP_HELPER and DRM_DISPLAY_HELPER, which is
in turn required by the former.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
