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.

drm/imx: imx-ldb: Accept drm_of_find_panel_or_bridge failure

2017-06-06T08:21:10Z

Not having an endpoint bound in DT should not cause a failure here, there are fallbacks. So explicitly accept a missing endpoint. This behavior change was introduced by refactoring in drm_of parsing code and it should not require dts changes. In particular this fixes imx6qdl-sabreauto boards.

drm: convert drivers to use drm_of_find_panel_or_bridge

2017-04-06T21:00:27Z

Similar to the previous commit, convert drivers open coding OF graph parsing to use drm_of_find_panel_or_bridge instead. This changes some error messages to debug messages (in the graph core). Graph connections are often "no connects" depending on the particular board, so we want to avoid spurious messages. Plus the kernel is not a DT validator.

drm: bridge: Detach bridge from encoder at encoder cleanup time

2016-12-18T11:02:49Z

Most drivers that use bridges forgot to detach them at cleanup time. Instead of fixing them one by one, detach the bridge in the core drm_encoder_cleanup() function.

drm: bridge: Link encoder and bridge in core code

2016-12-18T11:01:45Z

Instead of linking encoders and bridges in every driver (and getting it wrong half of the time, as many drivers forget to set the drm_bridge encoder pointer), do so in core code. The drm_bridge_attach() function needs the encoder and optional previous bridge to perform that task, update all the callers.

drm: Make the connector .detect() callback optional

2016-12-01T15:05:53Z

Many drivers (21 to be exact) create connectors that are always connected (for instance to an LVDS or DSI panel). Instead of forcing them to implement a dummy .detect() handler, make the callback optional and consider the connector as always connected in that case.

Instead let drm_mode_config_cleanup() do the work when taking down the master device. This requires all cleanup functions to be properly hooked up to the mode object .destroy callback. Signed-off-by: Lucas Stach Signed-off-by: Philipp Zabel
