[PATCH] V2: Currently, DRM get the capability of the mst hub only from DP_DPCD_REV and get the slower speed even the mst hub can run in the faster speed.

As per DP-1.3, First check DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT. If DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT is 1, read the DP_DP13_DPCD_REV to get the faster capability. If DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT is 0, read DP_DPCD_REV. Signed-off-by: Koba Ko --- ChangeLog: 1. use drm_dp_read_dpc

[RFC PATCH 3/3] drm: mxsfb: enforce framebuffer size matches plane size

The plane size must match the CRTC already (enforced by not setting the CAN_POSTION flag). However, the controller also requires the framebuffer to be exactly the CRTC size. Make use of the new flag DRM_PLANE_REQUIRE_MATCHING_FB to match the plane size. Signed-off-by: Stefan Agner --- drivers/gp
