2017-04-07drm/vmwgfx: Fix fbdev emulation using legacy functionsDaniel Vetter
I've broken this by removing the backoff handling from the set_config2atomic helper in commit 38b6441e4e75c0b319cfe4d9364c1059fc1e3c2b Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Mar 22 22:50:58 2017 +0100 drm/atomic-helper: Remove the backoff hack from set_config Fixing this properly would mean we get to wire the acquire_ctx all the way through vmwgfx fbdev code, and doing the same was tricky for the shared fbdev layer. Probably much better to look into refactoring the entire code to use the helpers, but since that's not a viable long-term solution fix the issue by open-coding a vmwgfx version of set_config, that does the legacy backoff dance internally. Note: Just compile-tested. The idea is to take drm_mode_set_config_internal(), remove the "is this a legacy driver" check, and whack the drm_atomic_legacy_backoff trickery at the end. Since drm_atomic_legacy_backoff is for atomic commits only we need to open-code it.

At dot clocks > approx. 250 Mhz, some of these calcs will overflow and cause miscalculation of latency watermarks, and for some overflows also divide-by-zero driver crash ("divide error: 0000 [#1] PREEMPT SMP" in "dce_v10_0_latency_watermark+0x12d/0x190").

2017-04-06drm: omap: use common OF graph helpersRob Herring
The OMAP driver has its own OF graph helpers that are similar to the common helpers. This commit replaces most of the calls with the common helpers. There's still a couple of custom helpers left, but the driver needs more extensive changes to get rid of them. In dss_init_ports, we invert the loop, looping through the known ports and matching them to DT nodes rather than looping thru DT nodes and matching them to the ports.

2017-04-06drm: convert drivers to use drm_of_find_panel_or_bridgeRob Herring
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.

2017-04-06drm: convert drivers to use of_graph_get_remote_nodeRob Herring
Convert drivers to use the new of_graph_get_remote_node() helper instead of parsing the endpoint node and then getting the remote device node. Now drivers can just specify the device node and which port/endpoint and get back the connected remote device node. The details of the graph binding are nicely abstracted into the core OF graph code. 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.

2017-04-06drm: of: introduce drm_of_find_panel_or_bridgeRob Herring
Many drivers have a common pattern of searching the OF graph for either an attached panel or bridge and then finding the DRM struct for the panel or bridge. Also, most drivers need to handle deferred probing when the DRM device is not yet instantiated. Create a common function, drm_of_find_panel_or_bridge, to find the connected node and the associated DRM panel or bridge device.

2017-04-06drm/atomic: Add connector atomic_check function, v2.Maarten Lankhorst
The atomic_check function is useful for implementing properties, but it can be used for other connector modeset related checks as well. Similar to plane check functions, on a modeset atomic_check() is always called. Changes since v1: - Make sure atomic_check() is called on any modeset.

2017-04-06drm/atomic: Move enable/connector check up in check_modeset()Maarten Lankhorst
Now that handle_conflicting_encoders no longer touches active state, so there's no need to do the check quite that late any more. Doing it with all the other checks makes it a lot more clear what the below block tries to accomplish, and this feels like a better place to put the check.

2017-04-06drm/atomic: Set all the changed flags in one place.Maarten Lankhorst
Now that handle_conflicting_encoders cannot disable crtc's any more it makes sense to set all the changed flags in 1 place. This makes the code slightly less magical. The (now removed) comment is out of date. The only reason the active_changed was set late was because handle_conflicting_encoders could disable connectors. This is no longer the case, and we can put everything in 1 place.

2017-04-06drm/atomic: Unify conflicting encoder handling.Maarten Lankhorst
Currently we use a flag to change behavior in atomic commit whether a conflicting encoder should be enabled or disabled. This is used for the legacy set_config helper, which disables connectors that have a conflicting encoder but not part of the active crtc list. There's no need for this to be handled in atomic commit, it could be done in the set_config helper instead. This will let the atomic check function reject any conflicting encoders, while set_config can disable conflicting crtc's. This makes it possible to recalculate the changed flags in 1 loop.
