Also, Exynos SoC doesn't include the physical otg block to detect the type of external connector(HOST or Peripheral). So, our team member and me are preparing the patches to identify the type of external connector with extcon This approach is not dependent on any specific SoC. Maybe, we will send the RFC patches within this month. -- Best Regards, Chanwoo Choi S/W R&D Center Samsung Electronics
