I realized that you are using same CONFIG option as the old one to build this driver. This causes new driver to fail to probe as old driver would bind to the node instead (both drivers will be built into the kernel and both drivers have same compatible). So, you should remove the old driver. Could you also include patches removing old driver? New driver and bindings are anyways backward compatible with existing one -- Regards Vignesh
