At the moment we have ovl_set_channel_out() to configure the output channel of an overlay. It makes sense to have this configuration as part of the rest of overlay configuration, and in DSS6+ we need the output channel when doing the other overlay configuration.

2017-06-02drm: omapdrm: Infer the OMAP version from the SoC familyLaurent Pinchart
The omapdrm exposes the SoC version to userspace through an integer that contains the OMAP model (e.g. 0x3430 for the OMAP3430). This is an unfortunate choice of userspace API as it's both conceptually wrong (userspace nowadays should use /sys/bus/soc/ for that purpose) and inaccurate as many models with different features are reported with the same version number. The only known user of this API is the xomap X11 driver. Even if it has been deprecated for some time we can't drop the kernel API yet. We can, however, infer the version number from the SoC family to avoid the need to pass the version number through platform data. Do this, which makes the omapdrm platform data not needed anymore, and ready to be removed.

2017-06-02drm: omapdrm: Take GEM object reference when exporting dmabufLaurent Pinchart
To ensure that neither the GEM object nor the DRM device goes away while a GEM object exported through dma-buf is still accessible, references must be taken to both the GEM object and the DRM device at export time. The dma-buf release handler already releases the GEM object, but the export handler doesn't take a corresponding reference, which results in a refcount underflow. Fix this by replacing the custom implementation by drm_gem_dmabuf_export() and drm_gem_dmabuf_release() that handle reference counting for us.

2017-06-02drm: omapdrm: Store the Z order in the plane state zpos fieldLaurent Pinchart
The DRM core implements a standard "zpos" property to control planes ordering. The omapdrm driver implements a similar property named "zorder".

2017-06-02drm: omapdrm: Remove legacy buffer synchronization supportLaurent Pinchart
The omapdrm driver uses a custom API to synchronize with the SGX GPU. This is unusable as such in the mainline kernel as the API is only partially implemented and requires additional out-of-tree patches. Furthermore, as no SGX driver is available in the mainline kernel, the API can't be considered as a stable mainline API. Now that the driver supports synchronization through fences, remove legacy buffer synchronization support. The two userspace ioctls are turned into no-ops to avoid breaking userspace and will be removed in the future.
