Know that you will need some power and clock management for properly free devices that do not depend on a binary only RTOS which does _everything_ behind our backs.
I didn't read the binding document[1], which I should have done. If simpledrm claims to be compatible with simple-framebuffer I assume it should support the entire binding doc which includes clocks, regulators and having the node under /chosen. I will lift the necessary code from simplefb.c and put it in the next version. The binding doc also mentions an optional display phandle property, but I can't find any reference to this in simplefb.c. Noralf.
