libdrm: add exynos drm support
this patch adds libdrm_exynos helper layer that inclues some intefaces for exynos specific gem and virtual display driver and also adds exynos module name to modtest and vbltest. Changelog v2: - fixed exynos broken ioctl. the pointer of uint64_t *edid should be removed. - removed unnecessary definitions. - added drm prime interfaces. this feature is used to share a buffer between drivers or memory managers and for this, please, refer to below links: http://www.mjmwired.net/kernel/Documentation/dma-buf-sharing.txt http://lwn.net/Articles/488664/ this patch is based on a link below: git://anongit.freedesktop.org/mesa/drm commit id: d72a44c7c4f5eea9c1e5bb0c36cb9e0224b9ca22 Reviewed-by: Rob Clark <rob@ti.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Rob Clark <rob@ti.com>
