2019-11-13drm/bridge: anx6345: Fix compilation breakage on systems without CONFIG_OFMaxime Ripard
The driver assumes that the platform uses the device tree, and thus relies on some fields (of_node) being declared in some structures (drm_bridge). This isn't true for all platforms, so make sure we can only compile the ANX6345 on platforms where DT support is selected.

2019-11-12drm/bridge: fix anx6345 compilation for v5.5Torsten Duwe
The anx6345 driver originally was copied from anx78xx.c, which has meanwhile seen a few changes. In particular, the removal of drm_dp_link helpers and the discontinuation to include drm_bridge.h from drm_crtc.h breaks compilation in linux-5.5. Apply equivalents of these changes to anx6345.c.

2019-11-09drm/mcde: dsi: Enable clocks in pre_enable() instead of mode_set()Stephan Gerhold
The DSI initialization sequence incorrectly assumes that the mode_set() function of the DRM bridge is always called when (re-)enabling the display. This is not necessarily the case. Keeping the device idle in the framebuffer console for a while results in the display being turned off using the disable() function. However, as soon as any key is pressed only (pre_)enable() are called. mode_set() is skipped because the mode has not been changed. In this case, the DSI HS/LP clocks are never turned back on, preventing the display from working. Fix this by moving a part of the initialization sequence from mode_set() to pre_enable(). Keep most of the video mode setup in mode_set() since most of the registers are only dependent on the mode that is set for the panel - there is no need to write them again each time we re-enable the display.

2019-11-09drm/mcde: dsi: Fix duplicated DSI connectorStephan Gerhold
Using a (single) DSI display with MCDE currently results in two "connected" connectors: Connector: DSI-1 id : 34 encoder id : 0 conn : connected size : 0x0 (mm) count_modes : 0 count_props : 5 props : 1 2 5 6 4 count_encoders : 1 encoders : 33 Connector: DSI-2 id : 35 encoder id : 33 conn : connected size : 53x89 (mm) count_modes : 1 count_props : 5 props : 1 2 5 6 4 count_encoders : 1 encoders : 33 Mode: "480x800" 480x800 60 Although both show up as connected, the first one does not have any size and no available modes. This confuses userspace tools (e.g. kmscube) who look for available modes for the first connector. The reason for the duplicated connector is that mcde_dsi.c and the DRM panel bridge helper both set up a DSI connector, with more or less the same code. The connector set up by the DRM panel bridge is the one that is correctly set up in the example above. Therefore we can just remove the connector setup from mcde_dsi.c and let the DRM core handle all the hard work.

2019-11-09drm/mcde: dsi: Delay start of video stream generatorStephan Gerhold
The initialization order for DSI video mode is important - if we enable the video stream generator (VSG) before the MCDE DSI formatter starts sending pixel data, it will immediately run into an error and disable itself again. Avoid this problem by delaying the activation of the VSG until the MCDE DSI formatter is properly set up and running (i.e. when mcde_dsi_bridge_enable() is called).

2019-11-09drm/mcde: Fix frame sync setup for video mode panelsStephan Gerhold
The MCDE driver differentiates only between "te_sync" (for hardware TE0 sync) and software sync (i.e. manually triggered updates) at the moment. However, none of these options work correctly for video mode panels. Therefore, we need to make some changes to make them work correctly: - Select hardware sync coming from the (DSI) formatter. - Keep the FIFO permanently enabled (otherwise MCDE will stop feeding data to the panel). - Skip manual software sync (this is not necessary in video mode). Automatically detect if the connected panel is using video mode and enable the necessary changes in that case.

2019-11-09drm/mcde: Provide vblank handling unconditionallyStephan Gerhold
At the moment, vblank handling is only enabled together with TE synchronization. However, the vblank IRQ is also working with on displays without TE synchronization (e.g. DSI video mode panels). It seems like the vblank IRQ is actually generated by the MCDE hardware for the channel. Therefore, the vblank handling should be working correctly in all the cases and we can enable it unconditionally.

Udl's GEM code and the generic SHMEM are almost identical. Replace the former with SHMEM. The dmabuf support in udl is being replaced with generic GEM PRIME functions.

Memory pages of locally created buffer objects are mmap'ed with caching enabled.

2019-11-07drm/gma500: Add page flip support on psb/cdvPaul Kocialkowski
Legacy (non-atomic) page flip support is added to the driver by using the mode_set_base CRTC function, that allows configuring a new framebuffer for display. Since the function requires the primary plane's fb to be set already, this is done prior to calling the function in the page flip helper and reverted if the flip fails. The vblank interrupt handler is also refactored to support passing an event. The PIPE_TE_STATUS bit is also considered to indicate vblank on medfield only, as explained in psb_enable_vblank. It was tested by running weston on both poulsbo and cedartrail.

2019-11-07drm/gma500: Add missing call to allow enabling vblank on psb/cdvPaul Kocialkowski
This adds a missing call to drm_crtc_vblank_on to the common DPMS helper (used by poulsbo and cedartrail), which is called in the CRTC enable path. With that call, it becomes possible to enable vblank when needed. It is already balanced by a drm_crtc_vblank_off call in the helper. Other platforms (oaktrail and medfield) use a dedicated DPMS helper that does not have the proper vblank on/off hooks. They are not added in this commit due to lack of hardware to test it with.
