This set of patches adds support for Tegra20 and Tegra30 host1x and 2D. It is based on linux-next-20130307. Changes in this version: * host1x memory data structures refactored * Some "nvhost" leftovers renamed to host1x Changes in previous version 6: * Rebased on latest tegradrm * Renamed tegradrm's host1x to host1x_drm * Indentation and line split fixed to follow tegradrm convention * Pointers to platform_device replaced with pointers to device * Added host1x allocator, and wired it in * Debug spew code fixed to access mem handles from host1x_job * CDMA code doesn't keep the mem handles anymore * Push buffer ops have been made generic code * Removed the pin_array optimization in host1x_job to simplify code * Large number of smaller changes The driver implements an allocator using the DRM CMA helper. Each buffer is assigned an ops structure to operate on it. In future the DRM CMA helper will be replaced with an own allocator to implement IOMMU support. host1x is the driver that controls host1x hardware. It supports host1x command channels, synchronization, and memory management. It is sectioned into logical driver under drivers/gpu/host1x and physical driver under drivers/host1x/hw. The physical driver is compiled with the hardware headers of the particular host1x version. The hardware units are described (briefly) in the Tegra2 TRM. Wiki page http://http.download.nvidia.com/tegra-public-appnotes/host1x.html also contains a short description of the functionality. The patch set merges tegradrm into host1x and adds 2D driver, which uses host1x channels and sync points. The patch set also adds user space API to tegradrm for accessing host1x and 2D.
