Why do we need yet another binding to describe something that's completely discoverable? I'm working on *removing* any need to set the bus width, either from th= e driver or from the DT, so I see this patch as step backwards. Can anyone help me understand if there's *any* valid use case where we want to specify a-priori the bus width, considering it's completely discoverable at run-time? --=20 Ezequiel Garc=C3=ADa, Free Electrons Embedded Linux, Kernel and Android Engineering http://free-electrons.com -- To unsubscribe from this list: send the line "unsubscribe devicetree" i= n the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
