usb: isp1760: udc: add missing usb_ep_set_maxpacket_limit()

2015-07-31T13:58:00+00:00

Since maxpacket_limit was introduced all UDC drivers should use
usb_ep_set_maxpacket_limit() function instead of setting maxpacket value
manually. ep.maxpacket_limit contains actual maximum maxpacket value
supported by hardware which is needed by epautoconf.

usb: isp1760: check for null return from kzalloc

2015-06-08T21:25:04+00:00

isp1760_ep_alloc_request allocates a structure with kzalloc without checking
for NULL and then returns a pointer to one of the structure fields. As the
field happens to be the first in the structure the caller can properly check
for NULL, but this is risky if the structure layout is changed later. Add an
explicit NULL check for the kzalloc return value

Detected with smatch static analysis:

drivers/usb/isp1760/isp1760-udc.c:816 isp1760_ep_alloc_request()
  error: potential null dereference 'req'.  (kzalloc returns null)

usb: isp1760: hcd: use new USB_RESUME_TIMEOUT

Make sure we're using the new macro, so our
resume signaling will always pass certification.

usb: isp1760: fix spin unlock in the error path of isp1760_udc_start

2015-03-24T16:38:58+00:00

Commit a124820de5fd ("usb: isp1760: fix possible deadlock in
isp1760_udc_irq") replaced spin_{un,}lock with spin_{un,}lock_irq{save,restore}.
However it missed an error path resulting in the smatch warning as below:

drivers/usb/isp1760/isp1760-udc.c:1230 isp1760_udc_start() warn: inconsistent returns 'irqsave:flags'.
Locked on:   line 1207
Unlocked on: line 1199

This patch fixes the spin unlock in the error path in isp1760_udc_start
thereby removing the smatch warning mentioned above.

usb: isp1760: add peripheral/device controller chip id

2015-03-10T20:33:24+00:00

As per the SAF1761 data sheet[0], the DcChipID register represents
the hardware version number (0001h) and the chip ID (1582h) for the
Peripheral Controller.

However as per the ISP1761 data sheet[1], the DcChipID register
represents the hardware version number (0015h) and the chip ID (8210h)
for the Peripheral Controller.

This patch adds support for both the chip ID values.
