This patch add support for Two Dimensional Animation and Compositing Engine (2D-ACE) on the Freescale SoCs. 2D-ACE is a Freescale display controller. 2D-ACE describes the functionality of the module extremely well its name is a value that cannot be used as a token in programming languages. Instead the valid token "DCU" is used to tag the register names and function names. The Display Controller Unit (DCU) module is a system master that fetches graphics stored in internal or external memory and displays them on a TFT LCD panel. A wide range of panel sizes is supported and the timing of the interface signals is highly configurable. Graphics are read directly from memory and then blended in real-time, which allows for dynamic content creation with minimal CPU intervention. The features: (1) Full RGB888 output to TFT LCD panel. (2) Blending of each pixel using up to 4 source layers dependent on size of panel. (3) Each graphic layer can be placed with one pixel resolution in either axis. (4) Each graphic layer support RGB565 and RGB888 direct colors without alpha channel and BGRA8888 BGRA4444 ARGB1555 direct colors with an alpha channel and YUV422 format. (5) Each graphic layer support alpha blending with 8-bit resolution. This is a simplified version, only one primary plane, one framebuffer, one crtc, one connector and one encoder for TFT LCD panel.

A couple of fixes from the previous pull request as well as gl3 support. There is one drm core change, an export of a previously private function. Take 2 implementing screen targets, this time with the fbdev code adjusted accordingly. Also there is an implementation of register-driven command buffers, that overrides the FIFO ring for command processing. It's needed for our upcoming hardware revision. * 'vmwgfx-next' of git://people.freedesktop.org/~thomash/linux: (35 commits) drm/vmwgfx: Fix copyright headers drm/vmwgfx: Add DX query support.

drm/tegra: Changes for v4.3-rc1 There are a bunch of non-critical fixes here that I've collected over the past few months, but the biggest part is Tegra210 support, in the DC, DSI and SOR/HDMI drivers.

Commit 4c21b8fd ("MIPS: seccomp: Handle indirect system calls (o32)") fixed indirect system calls on O32 but it also introduced a bug for MIPS64 where it erroneously modified the v0 (syscall) register with the assumption that the sycall offset hasn't been taken into consideration. This breaks seccomp on MIPS64 n64 and n32 ABIs. We fix this by replacing the addition with a move instruction.

struct exynos_drm_encoder was justing wrapping struct drm_encoder, it had only a drm_encoder member and the internal exynos_drm_encoders ops that was directly mapped to the drm_encoder helper funcs. So now exynos DRM uses struct drm_encoder directly, this removes completely the struct exynos_drm_encoder. v2: add empty .mode_fixup() and .mode_set() to DSI and DPI to avoid null pointer.

This functions was just hiding the encoder and connector creation in a way that was less clean than if we get rid of it. For example, exynos_encoder ops had .create_connector() defined only because we were handing off the encoder and connector creation to exynos_drm_create_enc_conn(). Without this function we can directly call the create_connector function internally in the code, without the need of any vtable access. It also does some refactoring in the code like creating a bind function for dpi devices. Signed-off-by:

This struct was just representing encoder information, it was a member of struct exynos_drm_encoder, so any code trying to access encoder data would have to go through the encoder struct, get the display struct and then get the data it want.
