2016-07-18drm/fsl-dcu: make fbdev support really optionalTobias Jakobi1-5/+0
Currently enabling Freescale DCU DRM support automatically pulls in fbdev dependency. However this dep is unnecessary since DRM core already handles this for us (DRM_FBDEV_EMULATION).

2016-05-03drm/fsl-dcu: add COMMON_CLK dependencyArnd Bergmann1-1/+1
The fsl dcu now uses the clk-provider interfaces, which are not available when CONFIG_COMMON_CLK is disabled: drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_drv.c: In function 'fsl_dcu_drm_probe': drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_drv.c:362:20: error: implicit declaration of function '__clk_get_name' [-Werror=implicit-function-declaration] pix_clk_in_name = __clk_get_name(pix_clk_in); This adds a Kconfig dependency to prevent the driver from being enabled in this case.

2015-08-19drm/layerscape: Add Freescale DCU DRM driverJianwei Wang1-0/+18
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.
