Subject: Re: [PATCH] arm64: dts: rockchip: add reg property to brcmf sub node

Hi,

Question for Heiko or rob+dt.
Where would should #address-cells and #size-cells go in the dts or to the dtsi.
In case they become required in a futhure rockchip-dw-mshc.yaml?
ie. Should we patch all XXX rockchip,rk3288-dw-mshc nodes with them?

Thanks
