How/why do you think so ? At some point, the PDs from the Audiomix IP block will be added to the drivers/soc/imx/imx8mp-blk-ctrl.c. Then, you'll have 2 drivers with the same address range and the imx8mp-blk-ctrl also has runtime PM enabled. My worry here is the possibility of imx8mp-blk-ctrl audiomix (when that will be added) will mess with the PD leaving your clock provider driver hanging. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
