usb: chipidea: usbmisc_imx: fix a possible NULL dereference

2015-11-18T07:27:12+00:00

of_match_device could return NULL, and so cause a NULL pointer
dereference later. Renaming tmp_dev to of_id (like all others do) in the
process.

usb: chipidea: usbmisc_imx: add non-burst setting for imx6

2015-08-14T02:03:56+00:00

With this setting and AHBBRST at SBUSCFG as "Incremental burst of
unspecified length", each non-burst size can be taken as single
transfer. It is benefit for non-burst size transfer.

usb: chipidea: usbmisc_imx: add imx6sx initialization routine

2015-03-18T15:19:10+00:00

Except the same process with earlier imx6, it has below two features:

- Choose which vbus voltage as vbus wakeup source
We choose B_SESSION_VALID as vbus wakeup source since when the system
goes to suspend, the vbus comparator can't compare the vbus voltage
for VBUS_VALID.

- Disable dp/dm (linestate) change as wakeup source at device mode
when the vbus is not there, we don't expect dp/dm change waking up
usb controller at this situation.

usb: chipidea: usbmisc_imx: add .set_wakeup interface

2015-03-18T15:19:09+00:00

This API is used to enable/disable usb wakeup, only imx6 series are
added, since I don't have other imx hardware on hand. Other imx users
can add their API according to reference manual after testing.

usb: chipidea: usbmisc_imx: delete clock information

2015-03-18T15:19:08+00:00

All imx usb controller's non core registers uses the same clock gate with
core registers, the usbmisc_imx is the library for imx glue driver, the
glue keeps clock on when it calls usbmisc_imx API to change non-core register.

Besides, we will support runtime pm in the future, it also needs to
close this clock when the usb is not in use.

Philipp Zabel also verifies it at imx6q platform, see
