AM57 and DRA7 are more or less the same thing from a s/w view of the world. I do have a few more descope patches to send upstream, but I am holding off on that since the promised TRM and data sheet update that was supposed to happen in March seems to have skipped that update, and I dont plan on posting code not backed by TI official documentation. > >>> From TI's perspective, despite a few of us community involved folks, >>> there is very less interest in investigating all the missing >>> features on OMAP5 at this point in time. >> Right, so for omap5 PM, it's mostly the omap5 PRCM related parts that >> are missing.

Yes, it should be. PRCM is a module inside the SoC that is responsible for Power Reset and Clock Management (hence PRCM).. all TI public TRMs based on SoCs using PRCM have it already. > We probably have them in our datasheets, but can the community add the > support? It is all there. -- Regards, Nishanth Menon -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
