This is a note to let you know that I've just added the patch titled usb: renesas_usbhs: fix usbhsc_resume() for !USBHSF_RUNTIME_PWCTRL to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 59a0879a0e17b2e43ecdc5e3299da85b8410d7ce Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda <yoshihiro.shimoda.uh@xxxxxxxxxxx> Date: Wed, 19 Jul 2017 16:16:54 +0900 Subject: usb: renesas_usbhs: fix usbhsc_resume() for !USBHSF_RUNTIME_PWCTRL This patch fixes an issue that some registers may be not initialized after resume if the USBHSF_RUNTIME_PWCTRL is not set. Otherwise, if a cable is not connected, the driver will not enable INTENB0.VBSE after resume. And then, the driver cannot detect the VBUS.
