[PATCH 4.19 083/346] usb: chipidea: ci_hdrc_imx: Pass DISABLE_DEVICE_STREAMING flag to imx6ul

From: Greg Kroah-Hartman
Date: Mon Dec 28 2020 - 08:23:56 EST


From: Fabio Estevam <festevam@xxxxxxxxx>

commit c7721e15f434920145c376e8fe77e1c079fc3726 upstream.

According to the i.MX6UL Errata document:
https://www.nxp.com/docs/en/errata/IMX6ULCE.pdf

ERR007881 also affects i.MX6UL, so pass the
CI_HDRC_DISABLE_DEVICE_STREAMING flag to workaround the issue.
