Platform devices are a Linux abstraction that don't correspond to any particular bus type in reality. We have some "*-generic" bindings. A name of that form might be more appropriate. Or we could choose an arbitrary OHCI implementation's vendor,ochi string and everything else can declare compatibility with that. > + - reg: Address range of the ohci registers. > + - interrupts: Should contain the ohci interrupt. > + > +Optional properties: > + - clocks: array of clocks > + - clock-names: clock names "ahb" and/or "ohci" A description of what the clocks are might be helpful. How about something like: - clocks: a list of phandle + clock specifier pairs, one for each entry in clock-names. - clock-names: Should contain: * "ahb" - some description here. * "ohci" - some description here.
