I know that Bjorn had previously sent an R-b, and Johan as well, but since the code changed, I didn't bring them forward. If I'm doing something wrong, please let me know! --steev

While unfortunately not mentioned in the cover letter, this one should go through the qcom tree once the binding and driver patches have been merged (i.e. Bjorn will pick it up). Johan

Please take only driver and bindings. The DTS should always go via Qualcomm SoC tree (as we want to be sure 100% that it is independent of driver). Best regards, Krzysztof
