drm/i915: extract intel_hotplug.h from intel_drv.h and i915_drv.h It used to be handy that we only had a couple of headers, but over time intel_drv.h has become unwieldy. Extract declarations to a separate header file corresponding to the implementation module, clarifying the modularity of the driver. Ensure the new header is self-contained, and do so with minimal further includes, using forward declarations as needed. Include the new header only where needed, and sort the modified include directives while at it and as needed. No functional changes. v2: fix sparse warnings on undeclared global functions Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190429125011.10876-1-jani.nikula@intel.com

drm: Move port definition back to i915 header We dont need the definition of the enum port outside I915, anymore. Hence move enum port definition into I915 driver itself. v2: intel_display.h is included in intel_hdcp.h v3: enum port is declared in headers. v4: commit msg is rephrased. v5: copyright year is updated [Tomas] Signed-off-by: Ramalingam C <ramalingam.c@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Shashank Sharma <shashank.sharma@intel.com> Reviewed-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Uma Shankar <uma.shankar@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190828164216.405-3-ramalingam.c@intel.com
