Subject: [PATCH 1/1] usb: chipidea: ci_hdrc_imx: Pass DISABLE_DEVICE_STREAMING flag to imx6ul
Date: Mon,  7 Dec 2020 10:09:09 +0800	[thread overview]
Message-ID: <20201207020909.22483-2-peter.chen@kernel.org> (raw)
In-Reply-To: <20201207020909.22483-1-peter.chen@kernel.org>

From: Fabio Estevam <festevam@gmail.com>

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.
