There is a fundamental question - should the bindings be considered an ABI, even though there is no mainline "*.dts" implementation basing on these bindings? This patch fixes the issues of bindings in a way that would change the ABI, if only it existed. But it apparently doesn't exist in mainline. Unless a DT documentation itself constitutes an ABI. I'd like to have it clarified at this occasion, and that's why I kindly ask for DT maintainer's ack or NACK for this modification of bindings. For a reference we have a nice summary of the MFD driver and related bindings' flaws in [0] and [1].
