It's sort of indirectly related, anyway, I utterly hope that the generic IC drivers will be ready and accepted for v4.21, see https://lwn.net/ml/devicetree/20181008211205.2900-1-vz@mleia.com/ Adding more ICs and cell devices to the framework is appreciated, in the queue there are DS90UB913, DS90Ux929, DS90Ux947, DS90UB964. Steve, in case if you're unaware, that's FYI also. -- Best wishes, Vladimir
