This patch set is based on v4.17-rc1. In last week, I submitted a patch as v1 [1]. But, the v1 patch doesn't use graphs to get usb host device pointer. So, I modified some frameworks for it. Since the patch 4 "of: platform: add device connection parsing" has TODOs, I marked this patch set as "RFC". Before I resolve them, I would like to know whether this way is good or not.
