This patch set is based on renesas-drivers-2018-04-17-v4.17-rc1 tag of renesas-drivers.git In last week, I submitted a patch as RFC [1]. But, I completely misunderstood the discussion of previous' one [2]. I marked this patch set as "RFC" because dtsi patch and udc patch are not good for upstreaming (should separate a few patches). I would like to know whether this way is good or not. [1] https://patchwork.kernel.org/patch/10347511/ [2] https://patchwork.kernel.org/patch/10332865/ Changes from RFC: - Remove "device-connection-id" and "usb role switch driver" dt-bingings. - Remove drivers/of code. - Add a new API for find the connection by using graph on devcon.c and roles.c. - Use each new API on the rcar usb role switch and renesas_usb3 drivers. - Update the dtsi file for r8a7795.
