[PATCH 50/60] drm/omap: displays: Remove unused panel drivers
Laurent Pinchart
laurent.pinchart at ideasonboard.com
Sun Jul 7 18:19:27 UTC 2019
drm_panel-based drivers for the ACX565AKM, LB035Q02, LS037V7DW01,
NL8048HL11, TD028TTEC1 and TD043MTEA1 are available, remove the
omapdrm-specific drivers.
