Subject: drm/i915/bdw: check DPD on port D when setting the DDI buffers
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=77d8d00944dd5a0a2f4f67809819df927ee23030;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/i915/bdw: check DPD on port D when setting the DDI buffers

Use the eDP values on platforms where port D is eDP. This doesn't
affect Haswell since it uses the same DDI buffer values for eDP and
DP.
