Yeah, I worked on it a bit around -rc4 time, but didn't get a chance to complete the cleanup & testing before I had to shift to some other tasks. If you are interested, I can share my branch. I will mostly get back to this towards the latter half of next week. Anyway, I am expecting 4.19-rc1 to be in a better shape w.r.t Davinci platform as the genpd and CCF stuff comes in, and the pm_runtime usage for clocking in my PRUSS drivers will fit well with those available. regards Suman -- 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
