* drivers: usb: xhci-fsl: Implement Erratum A-010151 for FSL USB3 controllerSriram Dash2016-09-27-0/+1
| | | | | | | | | | | Currently the controller by default enables the Receive Detect feature in P3 mode in USB 3.0 PHY. However, USB 3.0 PHY does not reliably support receive detection in P3 mode. Enabling the USB3 controller to configure USB in P2 mode whenever the Receive Detect feature is required.

* drivers: usb: fsl: Workaround for Erratum A004477Nikhil Badola2015-05-04-0/+29
| | | | | | | | | | Add a delay of 1 microsecond before issuing soft reset to the controller to let ongoing ULPI transaction complete. This prevents corruption of ULPI Function Control Register which eventually prevents phy clock from entering to low power mode Signed-off-by: Nikhil Badola <nikhil.badola@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>

* powerpc/usb: Workaround for erratum-A006261Suresh Gupta2014-03-07-2/+21
| | | | | | | | | | | USB spec says that the minimum disconnect threshold should be over 525 mV. However, internal USB PHY threshold value is below this specified value. Due to this some devices disconnect at run-time. Hence, phy settings are tweaked to increased disconnect threshold to be above 525mV by using this workaround.
