[PATCH 1/5] drm/exynos: hdmi: Replace drm_detect_hdmi_monitor() with is_hdmi

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi.

This driver calls drm_detect_hdmi_monitor() to receive the same
information and stores its own cached value, which is less efficient.

Avoid calling drm_detect_hdmi_monitor() and use drm_display_info.is_hdmi
instead and also remove hdmi_context.dvi_mode as it is no longer
necessary.
