[3]https://patchwork.kernel.org/project/dri-devel/list/?series=633565 Going forward we use a drm_connector which is not embedded in intel_connector. We also create a intel_encoder to avoid changes to many iterators but no intel_connector. We also changed all iterators that ---v2 solving BAT issues ---v3 -removing unecessary comments from i915_reg.h [Arun] -moving wd_init into its own if condition [Arun] -fixing comment styling and alignment in intel_wd.c [Arun] -removing continue from loop and calling function if condition is met [Arun] -removing useless arguments from intel_queue_writeback_job and intel_enabling_capture [Arun] --v4 Adding Reviewed-by to patches which were previously reviewd Suraj Kandpal (3): drm/i915: Define WD trancoder for i915 drm/i915 : Changing intel_connector iterators drm/i915: Enabling WD Transcoder drivers/gpu/drm/i915/Makefile | 1 + drivers/gpu/drm/i915/display/intel_acpi.c | 1 + drivers/gpu/drm/i915/display/intel_crtc.c | 6 + .../drm/i915/display/intel_crtc_state_dump.c | 1 + drivers/gpu/drm/i915/display/intel_ddi.c | 6 + drivers/gpu/drm/i915/display/intel_display.c | 68 +- drivers/gpu/drm/i915/display/intel_display.h | 18 +- .../drm/i915/display/intel_display_debugfs.c | 13 +- .../drm/i915/display/intel_display_types.h | 32 +- drivers/gpu/drm/i915/display/intel_dpll.c | 6 + .../drm/i915/display/intel_modeset_setup.c | 119 ++- .../drm/i915/display/intel_modeset_verify.c | 17 +- drivers/gpu/drm/i915/display/intel_opregion.c | 3 + drivers/gpu/drm/i915/display/intel_wd.c | 695 ++++++++++++++++++ drivers/gpu/drm/i915/display/intel_wd.h | 48 ++ drivers/gpu/drm/i915/i915_drv.h | 1 + drivers/gpu/drm/i915/i915_irq.c | 8 +- drivers/gpu/drm/i915/i915_pci.c | 7 +- drivers/gpu/drm/i915/i915_reg.h | 137 ++++ 19 files changed, 1132 insertions(+), 55 deletions(-) create mode 100644 drivers/gpu/drm/i915/display/intel_wd.c create mode 100644 drivers/gpu/drm/i915/display/intel_wd.h
