2019-06-13drm/mcde: Fix an uninitialized variableDan Carpenter1-1/+1
We never set "vblank" to "false". Current versions of GCC will initialize it to zero automatically at certain optimization levels so that's probably why this didn't show up in testing.

2019-05-24drm/mcde: Add new driver for ST-Ericsson MCDELinus Walleij8-0/+3726
This adds a new DRM driver for the ST-Ericsson Multi Channel Display Engine, MCDE display controller. This hardware has three independent DSI hosts and can composit and display several memory buffers onto an LCD display. It was developed for several years inside of ST-Ericsson and shipped with a few million mobile phones from Sony and Samsung, as well as with the Snowball community development board. The driver is currently pretty rudimentary but supports a simple framebuffer so we can get penguins and graphics when using these SoCs.
