USB: change bInterval default to 10 ms

2016-09-29T09:14:25+00:00

commit 08c5cd37480f59ea39682f4585d92269be6b1424 upstream.

Some full-speed mceusb infrared transceivers contain invalid endpoint
descriptors for their interrupt endpoints, with bInterval set to 0.
In the past they have worked out okay with the mceusb driver, because
the driver sets the bInterval field in the descriptor to 1,
overwriting whatever value may have been there before.  However, this
approach was never sanctioned by the USB core, and in fact it does not
work with xHCI controllers, because they use the bInterval value that
was present when the configuration was installed.

Currently usbcore uses 32 ms as the default interval if the value in
the endpoint descriptor is invalid.  It turns out that these IR
transceivers don't work properly unless the interval is set to 10 ms
or below.  To work around this mceusb problem, this patch changes the
endpoint-descriptor parsing routine, making the default interval value
be 10 ms rather than 32 ms.

usb: renesas_usbhs: fix clearing the {BRDY,BEMP}STS condition

2016-09-29T09:14:25+00:00

commit 519d8bd4b5d3d82c413eac5bb42b106bb4b9ec15 upstream.

The previous driver is possible to stop the transfer wrongly.
For example:
 1) An interrupt happens, but not BRDY interruption.
 2) Read INTSTS0. And than state->intsts0 is not set to BRDY.
 3) BRDY is set to 1 here.
 4) Read BRDYSTS.
 5) Clear the BRDYSTS. And then. the BRDY is cleared wrongly.

Remarks:
 - The INTSTS0.BRDY is read only.
  - If any bits of BRDYSTS are set to 1, the BRDY is set to 1.
  - If BRDYSTS is 0, the BRDY is set to 0.

So, this patch adds condition to avoid such situation. (And about
NRDYSTS, this is not used for now. But, avoiding any side effects,
this patch doesn't touch it.)
