This kind of interface needs a LCD with an embedded graphic controller partially controlled by GPIO. I want to link it with an OLED DD12832. How have I to write this driver : One driver for SLCDC and one driver for DD12832 ? How to link them together ? Maybe use similar philosophy than soc-camera ? I have written a driver for kernel 2.6.22 but SLCDC and DD12832 are in the same driver. Thank you for your help. Gaëtan Carlier ps : I attach my previous driver for a better overview (this is a working draft for test purpose) --------------080906090607040704010200 Content-Type: text/x-csrc;
