2017-10-10T09:32:35Z

Make sure that bridge parameter is not NULL and can be safely cast into a panel_bridge structure.

drm: Nuke drm_atomic_helper_connector_dpms

2017-08-08T12:48:48Z

It's dead code, the core handles all this directly now. The only special case is nouveau and tda988x which used one function for both legacy modeset code and -nv50 atomic world instead of 2 vtables. But amounts to exactly the same. v2: Rebase over the panel/brideg refactorings in stm/ltdc.

I need this to be able to apply the deferred fbdev setup patches, I need the relevant prep work that landed through the drm-intel tree. Also squash in conflict fixup from Laurent Pinchart. Signed-off-by: Daniel Vetter

drm/bridge: Refactor out the panel wrapper from the lvds-encoder bridge.

2017-06-05T08:30:40Z

Many DRM drivers have common code to make a stub connector implementation that wraps a drm_panel. By wrapping the panel in a DRM bridge, all of the connector code (including calls during encoder enable/disable) goes away. v2: Fix build with CONFIG_DRM=m, drop "dev" argument that should just be the panel's dev, move kerneldoc up a level and document _remove(). v3: Fix another breakage with CONFIG_DRM=m, fix breakage with CONFIG_OF=n, move protos under CONFIG_DRM_PANEL_BRIDGE, wrap a line.
