[PATCH v6 02/11] drm/i915: Remove hw.mode

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

 



From: Maarten Lankhorst <maarten.lankhorst@xxxxxxxxxxxxxxx>

The members in hw.mode can be used from adjusted_mode as well,
use that when available.

Some places that use hw.mode can be converted to use adjusted_mode
as well.

v2:
* Manual rebase (Manasi)
* remove the use of pipe_mode defined in patch 3 (Manasi)

v3:
* Rebase on drm-tip (Manasi)
