Hi Sergei,

You're right, I haven't seen the pxa2xx.dtsi statement before.

As such, could you amend a bit your patch please to :
 - add:
Fixes: 0ec1939668e5 ("ARM: dts: pxa: add the usb host controller")
 - make the same change in pxa3xx.dtsi, as the same error is there
 - and more globally align pxa2xx.dtsi, pxa27x.dtsi and pxa3xx.dtsi
 - remove the compatible, reg, interrupts and status from both pxa27x.dtsi and
   pxa3xx.dtsi as they are redundant with the included pxa2xxx.dsti one

I'm even wondering if the proper change wouldn't be to scrap the ohci
declarations from pxa27x.dtsi and pxa3xx.dtsi, and only add the "clocks"
property to pxa2xx.dtsi ...

Cheers.
