Hi Philipp, I am working on the USB2.0 IP block that has a USB2PHY control, this is mainly to control reset and power down of the USB2PHY. I have modelled the USB2PHY control block as a reset driver. There is one register bit which I need to set in this block depending on the USB channel if its host/function. Only the USB PHY can know if it's a host/function so this somehow needs to be propagated to the USB2PHY control reset driver to set the appropriate bits. The current reset core does not have any api to do so. Currently I was thinking of the below (yet to implement), - add a new callback in reset_control_ops (int(*configure)(struct reset_controller_dev *rcdev, void *data);) - from the USB phy driver get the reset pointer - Call the configure() callback from USB phy driver Can you please let me know if this approach should be OK? or let me know if there is an alternative way to solve this. Cheers, Prabhakar
