2017-04-03drm/msm: Make sure to detach the MMU during GPU cleanupJordan Crouse
We should be detaching the MMU before destroying the address space. To do this cleanly, the detach has to happen in adreno_gpu_cleanup() because it needs access to structs in adreno_gpu.c.

2017-04-03drm/msm/dsi: Fix bug in dsi_mgr_phy_enableArchit Taneja
A recent commit introduces a bug in dsi_mgr_phy_enable. In the non dual DSI mode, we reset the mdsi (master DSI) PHY. This isn't right since master and slave DSI exist only in dual DSI mode. For the normal mode of operation, we should simply reset the PHY of the DSI device (i.e. msm_dsi) corresponding to the current bridge. Usage of the wrong DSI pointer also resulted in a static checker warning. That too is resolved with this fix.

2017-04-03drm/omap: Major omap_modeset_init() cleanupJyri Sarha
Cleanup overly complex omap_modeset_init(). The function is trying to support many unusual configuration, that have never been tested and are not supported by other parts of the dirver. After cleanup the init function creates exactly one connector, encoder, crtc, and primary plane per each connected dss-device. Each connector->encoder->crtc chain is expected to be separate and each crtc is connect to a single dss-channel. If the configuration does not match the expectations or exceeds the available resources, the configuration is rejected.

2017-04-03drm/omap: fix display SYNC/DE flagsTomi Valkeinen
At the moment VSYNC/HSYNC/DE high/low flags set by the panel/encoder drivers get lost when the videotimings are translated to DRM's videomode, as DRM's mode does not have corresponding flags. DRM has bus-flags for this purpose, and while it lacks a few flags at the moment, it should be used here. However, until we rewrite omapdrm's device model, using bus-flags is rather difficult. As a short term fix, this patch makes sure that every time the videomode is set in omap_crtc_mode_set_nofb(), the driver asks for the SYNC/DE flags from the panel/encoder drivers, and thus we get the correct flags into use.

2017-04-03drm/omap: fix replication logicTomi Valkeinen
DSS uses "replication logic" to convert color components from smaller bit widths to bigger bit widths. Without replication logic, the color component would be shifted and the least significant bits would be left at 0, whereas with replication logic, the least significat bits will be filled with the most significant bit. For some reason omapdrm leaves replication logic always to off, which, in the most common case, means that showing 16-bit RGB colors on 24-bit display gives a bit darker colors than expected. The reset value of the replication logic bit is enabled, and it should always be set, as there's no practical reason to disable it. This patch removes the option to disable it from omapdrm, and always sets it to enabled in dispc.

Change omapdrm to get dispc_ops and use that to call the dispc functions instead or direct function calls. The change is very straightforward.

2017-04-03drm/omap: move dispc related dss-feat funcs to dispcTomi Valkeinen

We want to provide omapdrm a single dispc_ops function pointer struct so that omapdrm will use either the current omapdss or the new omapdss6 driver depending on the platform. Those three functions are really dispc functions, but are located in the dss_features.c for legacy reasons.

2017-04-03drm/omap: fix HDMI sync polaritiesTomi Valkeinen
While implementing writeback support, odd behavior of WBDELAYCOUNT was observed with the combination of WB capture and HDMI. The result of the debugging was that the HDMI sync polarities are not set correctly. The current code sets the sync polarities going from HDMI WP to DISPC according to the video mode used, which seems to work normally fine, but causes problems with WB as WB expects the syncs to be active-high.

2017-04-03drm/omap: Add support for render nodesHemant Hariyani
Add support for render nodes in omap driver and allow required ioctls to be accessible via render nodes. This enables unprivileged clients to allocate resources like GEM buffers for rendering their content into. Mode setting (KMS ioctls) is not allowed using render nodes. These buffers are then shared with a previleged process (e.g compositor) that has mode setting access. An example of this use case is Android where the hardware composer is the only master and has mode setting access. Every other client then uses render node(e.g /dev/dri/renderD128 to allocate and use its buffers.

2017-04-03drm/bridge: megachips-stdpxxxx-ge-b850v3-fw: Fix bridge initializationPeter Senna Tschudin
Reordering of the device nodes based on unit address resulted in ge_b850v3_lvds_attach() being called before ge_b850v3_lvds_ptr->stdp4028_i2c was populated. This patch moves the drm bridge initialization from ge_b850v3_lvds_init() to stdp4028_ge_b850v3_fw_probe() ensuring that ge_b850v3_lvds_ptr->stdp4028_i2c is properly populated.
