As time has passed, we have moved forward and learned something. We would not write a binding like this today. Admittedly I went dormant (did not provide an update) since v6. There are several issues. - The MPC512x DMA completely lacks a binding document, so one should get added. - The MPC8308 hardware is similar and can re-use the MPC512x binding, which should be stated. - The Linux implementation currently has no OF based channel lookup support, so '#dma-cells' is "a future feature". I guess the binding can and should already discuss the feature, regardless of whether all implementations support it. virtually yours Gerhard Sittig -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr. 5, D-82194 Groebenzell, Germany Phone: +49-8142-66989-0 Fax: +49-8142-66989-80 Email: office@xxxxxxx -- 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
