The directory should perhaps be something like ti-lcdc? Probably not relevant, but I wonder if the same LCDC was used in omap1... It'd be nice to get rid of the omap1 fb driver. I'm not very enthusiastic about adding ti-lcdc specific panel/chip drivers. It's not really a big deal if it's only kernel code, but you add device-tree bindings also, which is an external API that you need to support after adding it. I'd rather see the energy put to common display framework, and get this whole panel/chip driver issue solved in a generic manner. Tomi
