The problem with accepting this patch as is, is that the burden of creating the uclass (which is actually not that large at all) falls on the second driver submitter, as well as the burden of converting your driver. In practice what happens is that no one can be bothered. See UCLASS_PCH for a simple uclass. You just need to define the API (which may just be empty), any uclass-private struct then add something to test.dst and a simple test to test/dm/extcon.c Regards Simon

First of all, thanks for your reviews, all of them apart from those I have responded to are fairly reasonable and will be implemented. About extcon uclass. My vision is to leave this driver as is in misc for some time and check if there will be any other extcon devices added. In case these devices become at least sometimes used on supported devices there will be good reasons to create a new uclass. As for now, it is a bit pointless to waste time for a new uclass and new framework for only one device used by one board. Best regards, Svyatoslav R.
