So you want to make the code conform to the common spec which has bus-width as a required property. Is this really worth it to add an incompatible change to our devicetrees?I do want to have our implementation conform to common spec. At the current stage devicetrees are not stable anyway, so we should make them right as much as possible before they start getting maintained separately from kernel tree, where we will be asked to maintain devicetree compatibility a lot harder.
Ok, how about this: - I add a bus-width = <4> property to all i.MX dtsi files - we merge the patch adding bus-width as an optional property - Make the bus-width option mandatory in the next step. This way we can merge the mmc related patches through the mmc tree and the dts changes through arm-soc.
