2014-12-11fb: Add DCU framebuffer driver for LS1021A platformXiubo Li
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) For the current LCD panel, WQVGA "480x272" is supported. (3) Blending of each pixel using up to 4 source layers dependent on size of panel. (4) Each graphic layer can be placed with one pixel resolution in either axis. (5) Each graphic layer support RGB565 and RGB888 direct colors without alpha channel and BGRA8888 direct colors with an alpha channel. (6) Each graphic layer support alpha blending with 8-bit resolution.

2014-04-10net: sysrq via icmpCarsten Emde
There are (probably rare) situations when a system crashed and the system console becomes unresponsive but the network icmp layer still is alive. Wouldn't it be wonderful, if we then could submit a sysreq command via ping? This patch provides this facility. Please consult the updated documentation Documentation/sysrq.txt for details.
