Sure, but I had the understanding based on our last communication that you are going to go with partial support for now and multiple domain thing will be done later on. > What I have been testing with these patches is to move a single user (MMC, which BTW does not > have to put requests on multiple powerdomains) to use this solution on a db820c (msm8996) device.

Even on that I thought that you will artificially vote for a high requirement for those devices from some platform code initially, and remove that code once all the device drivers (you need) are updated to post their own requirements. -- viresh -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
