+Subject: [PATCH] usb: host: xhci-plat: add firmware for the R-Car M3-W xHCI
+ controllers
+
+This patch adds a firmware for the USB 3.0 host controllers of Renesas
+R-Car M3-W SoC.
+
+ - This firmware is possible to be used on R-Car H2 and M2. However,
+ this version causes performance degradation on such SoCs.
+ - This firmware is impossible to be used on R-Car H3 because data
+ transfer might not work correctly.
+
+So, we would like to keep the v1 and v2 firmware.
