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.

drm/imx: parallel-display: detach bridge or panel on unbind

2016-08-29T14:30:48Z

Don't leave any bridge or panel attached to a stale driver instance when unbinding, to allow reattachment on a rebind. Signed-off-by: Philipp Zabel

drm/imx: don't destroy mode objects manually on driver unbind

2016-08-29T10:45:05Z

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

drm/imx: convey the pixelclk-active and de-active flags from DT to the ipu-di driver

2016-08-08T09:44:20Z

The 'de-active' and 'pixelclk-active' DT properties are evaluated by of_parse_display_timing() called from of_get_drm_display_mode(), but later lost in the conversion from videomode.flags to drm_display_mode.flags. Enhance of_get_drm_display_mode() to also return the bus flags in a separate variable, so that they can be passed on to the ipu-di driver. Signed-off-by: Lothar Waßmann Signed-off-by: Philipp Zabel

drm/imx: store internal bus configuration in crtc state

2016-07-12T16:24:28Z

The internal bus configuration is imx-drm specific crtc state. Store it in imx_crtc_state and let the encoder atomic_check callbacks determine bus_flags, bus_format and the sync pins, possibly taking into account the mode and the connector display info. The custom imx_drm_encoder structure can be replaced again with drm_encoder. Signed-off-by: Philipp Zabel
