I guess the fin_pll parts of the binding description are not needed then. This isn't a big issue, but I think that someone reading that binding (like myself) might conclude that there is some relationship between the clock controller and the external clock, which seems not to be the case. > > BTW, I've applied this series with Tomasz Figa's reviewed tag and sent out to arm-soc today so if any concerns on this, please let me know immediately. As far as I can tell the fin_pll paragraph can be removed at a later date. It isn't part of any real DT binding description such as a property or definition.
