[PATCH RFC 1/4] usb: chipidea: udc: move write barrier into hw_ep_prime

Since there should be a write barrier before every call of hw_ep_prime we could move it into hw_ep_prime. Signed-off-by: Stefan Wahren --- drivers/usb/chipidea/udc.c |8 +++- 1 file changed, 3 insertions(+), 5 deletions(-) diff --git a/drivers/usb/chipidea/udc.c b/drivers/usb/chipidea/u

[PATCH RFC 3/4] usb: chipidea: udc: Avoid busy wait in reset ISR

Since there is no dependency from this busy wait in the reset ISR we could remove it. Signed-off-by: Stefan Wahren --- drivers/usb/chipidea/udc.c |4 1 file changed, 4 deletions(-) diff --git a/drivers/usb/chipidea/udc.c b/drivers/usb/chipidea/udc.c index fdcdcc6..bb51ae8 100644 --- a/

[PATCH] usb: misc: Add driver for usb4604

This is a minimal driver to support bringing a usb4604 device from microchip out of reset and into hub mode. The usb4604 device is related to the usb3503 device, but it didn't seem close enough to warrant putting both into the same file. This patch borrows some of the usb3503 structure and trims it

[PATCH] usb: ulpi: Automatically set driver::owner with ulpi_driver_register()

Let's follow other driver registration functions and automatically set the driver's owner member to THIS_MODULE when ulpi_driver_register() is called. This allows ulpi driver writers to forget about this boiler plate detail and avoids common bugs in the process. Cc: Heikki Krogerus Signed-off-by:
