No can do. This isn't _this_ device's register offset, this is a syscfg register offset which a) there is no driver to apply specific register offsets to and b) are liable to change oversubsequent SoCs. > The syscfg phandle is elegant though, really like that. -- Lee Jones Linaro STMicroelectronics Landing Team Lead Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
