Hi! This series adds support for an 8-bit clut mode in the atmel-hlcdc driver. For various reasons I have only tested it with the fbdev interface, and am therefore not really sure if it works w/o patch 2 and 3. Also, when using it with the fbdev emulation layer, something seems to allocate the first 16 clut entries, which throws my users of ioctl(fb, FBIOPUTCMAP, ...) when index 0 in the given clut is really pixel value 16. If anyone can shed some light on that, I'd be most greatful! Further, I suspect I might need to lock the crtc state when accessing it in patch 3/3?
