staging: add omapdrm DRM/KMS driver for TI OMAP platforms A DRM display driver for TI OMAP platform. Similar to omapfb (fbdev) and omap_vout (v4l2 display) drivers in the past, this driver uses the DSS2 driver to access the display hardware, including support for HDMI, DVI, and various types of LCD panels. And it implements GEM support for buffer allocation (for KMS as well as offscreen buffers used by the xf86-video-omap userspace xorg driver). The driver maps CRTCs to overlays, encoders to overlay-managers, and connectors to dssdev's. Note that this arrangement might change slightly when support for drm_plane overlays is added. For GEM support, non-scanout buffers are using the shmem backed pages provided by GEM core (In drm_gem_object_init()). In the case of scanout buffers, which need to be physically contiguous, those are allocated with CMA and use drm_gem_private_object_init().

drm/omap: DMM/TILER support for OMAP4+ platform Dynamic Memory Manager (DMM) is a hardware block in the OMAP4+ processor that contains at least one TILER instance. TILER, or Tiling and Isometric Lightweight Engine for Rotation, provides IOMMU capabilities through the use of a physical address translation table. The TILER also provides zero cost rotation and mirroring. The TILER provides both 1D and 2D access by providing different views or address ranges that can be used to access the physical memory that has been mapped in through the PAT. Access to the 1D view results in linear access to the underlying memory. Access to the 2D views result in tiled access to the underlying memory resulted in increased efficiency. The TILER address space is managed by a tiler container manager (TCM) and allocates the address space through the use of the Simple Tiler Allocation algorithm (SiTA). The purpose of the algorithm is to keep fragmentation of the address space as low as possible.

omapdrm-y := omap_drv.o \
staging: drm/omap: use omapdss low level API This patch changes the omapdrm KMS to bypass the omapdss "compat" layer and use the core omapdss API directly. This solves some layering issues that would cause unpin confusion vs GO bit status, because we would not know whether a particular pageflip or overlay update has hit the screen or not. Now instead we explicitly manage the GO bits in dispc and handle the vblank/framedone interrupts ourself so that we always know which buffers are being scanned out at any given time, and so on. As an added bonus, we no longer leave the last overlay buffer pinned when the display is disabled, and have been able to add the previously missing vblank event handling. v1: original v2: rebased on latest staging-next and omapdss patches from Tomi and review comments from Archit Taneja Signed-off-by: Rob Clark <robdclark@gmail.com> Reviewed-by: Archit Taneja <archit@ti.com> Reviewed-by: Sumit Semwal <sumit.semwal@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

omap_crtc.o \
staging: drm/omap: add drm_plane support Because framebuffer layer and overlay scanout video pipes are basically thing in OMAP display subsystem (the only difference being that the first video pipe does not support scaling or YUV formats), much of the CRTC code is pulled into the plane implementation, and a private plane object is used by the CRTC object. This avoids code duplication between the plane and CRTC. Signed-off-by: Rob Clark <rob@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
