2017-07-26drm/atomic: implement drm_atomic_helper_commit_tail for runtime_pm usersMaxime Ripard1-26/+1
The current drm_atomic_helper_commit_tail helper works only if the CRTC is accessible, and documents an alternative implementation that is supposed to be used if that happens. That implementation is then duplicated by some drivers. Instead of documenting it, let's implement an helper that all the relevant users can use directly.

2017-07-14drm: handle HDMI 2.0 VICs in AVI info-framesShashank Sharma1-1/+1
HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64). For any other mode, the VIC filed in AVI infoframes should be 0. HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is extended to (VIC 1-107). This patch adds a bool input variable, which indicates if the connected sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a HDMI 2.0 VIC to a HDMI 1.4 sink. This patch touches all drm drivers, who are callers of this function drm_hdmi_avi_infoframe_from_display_mode but to make sure there is no change in current behavior, is_hdmi2 is kept as false. In case of I915 driver, this patch: - checks if the connected display is HDMI 2.0. - HDMI infoframes carry one of this two type of information: - VIC for 4K modes for HDMI 1.4 sinks - S3D information for S3D modes As CEA-861-F has already defined VICs for 4K videomodes, this patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks, until the mode is 3D.

2017-04-06drm: convert drivers to use drm_of_find_panel_or_bridgeRob Herring1-23/+12
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 Herring3-49/+5
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.

2017-03-21drm/exynos/dsi: make te-gpios optionalAndrzej Hajda1-1/+4
DSI forwards te-gpios interrupts to display controller, but if display controller works in HW-TRIGGER mode this interrupt is not necessary. Making te-gpios property optional allows to avoid generating spare interrupts. And also if panel device node of command mode panel device doesn't provide te-gpios property then the panel driver failed to probe. This was a critial issue. With this patch we can not only get rid of 60 interrupt callbacks per second but also fix the critial issues.
