We'd need separate DT files for each OMAP ES version. you can overwrite attributes on your board dts file, right ? Meaning that e.g. omap4.dtsi would have: dss1: dss@xxxx { compatible = "ti, omap4-dss"; }; then on omap4-based-board.dts: &dss1 { compatible = "ti,omap4-based-board-dss"; }; or something similar. Isn't that doable ? Benoit, would this work on DTS ? -- balbi
