This is an attempt at providing a DRM version of drivers/staging/fbtft. The tinydrm library provides a very simplified view of DRM in particular for tiny displays that has onboard video memory and is connected through a slow bus like SPI/I2C. Only core patches this time. Noralf. Changes since version 1: - Add tinydrm.rst - Set tdev->fbdev_cma=NULL on unregister (lastclose is called after that). - Remove some DRM_DEBUG*() - Write-combined memory has uncached reads, so speed up by copying/buffering one pixel line before conversion.
