Thanks very much. I'm also working with a tree with some hacked-in regulators and a new qcom clock controller. I seem to be missing the driver for the chipidea block. I don't have anything in my tree with a compatible string of "qcom,ci-hdrc". I do have an ehci-msm.c file, with a compatible string of "qcom,ehci-host". Sorry for asking newbie questions, but I'm trying to figure out the relationship between the different files, drivers and IP blocks, and which are applicable to the OTG port on the dragonboard. (I did find that the other ports all seem to go through external USB hub chips). Can you tell me what driver in your tree has the compatible string of "qcom,ci-hdrc"? Thanks for any direction you can provide. -- Tim On Thu, Jan 30, 2014 at 7:20 AM, Ivan T.
