2018-10-29fsl/usb: Workaround for USB erratum-A005275Chris Packham
Workaround makes FS as default mode on all affected socs. Add support to check erratum-A005275 validity for an soc. This info is required to determine whether a given soc is affected by this erratum. Add quirk for this erratum "has_fsl_erratum_a005275" . This quirk is used to enable workaround for the errata Force FS mode as default by: - making EPS as FS - setting PFSC bit to disable HS chirping This workaround can be disabled by mentioning "no_erratum_a005275" in hwconfig string Signed-off-by: Chris Packham <judge.packham@gmail.com> Reviewed-by: York Sun <york.sun@nxp.com>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2016-09-27drivers: usb: xhci-fsl: Implement Erratum A-010151 for FSL USB3 controllerSriram Dash
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.

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>

2014-03-07powerpc/usb: Workaround for erratum-A006261Suresh Gupta
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.
