Okay. I will revise the description. >> + it is necessary to reference the sys link. > This tells me nothing. You must be specific - WHAT IS THE PURPOSE of > this syscon usage in USB2 PHY? Sorry, I misunderstood. I will correct the description. Thank you for the reminder. > Best regards, > Krzysztof Best regards, Hui-Ping Chen
