| Subject: phy: renesas: rcar-gen3-usb2: fix vbus_ctrl for role sysfs |
| |
| From: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> |
| |
| [ Upstream commit 09938ea9d136243e8d1fed6d4d7a257764f28f6d ] |
| |
| This patch fixes and issue that the vbus_ctrl is disabled by |
| rcar_gen3_init_from_a_peri_to_a_host(), so a usb host cannot |
| supply the vbus. |
| |
| Note that this condition will exit when the otg irq happens |
| even if we don't apply this patch. |
| |
