Subject: [PATCH 2/2] ARM: dts: imx6qdl-udoo: Enable USB host
Date: Sun, 31 Mar 2024 23:33:47 -0300 [thread overview]
Message-ID: <20240401023347.3114484-2-festevam@gmail.com> (raw)
In-Reply-To: <20240401023347.3114484-1-festevam@gmail.com>
From: Fabio Estevam <festevam@denx.de>
Commit 8f2ca252ee1f ("ARM: dts: imx6qdl-udoo: Disable USB host to
work around boot issues") disabled USB host to avoid boot hang.
Properly describe the USB2514 USB hub to fix this issue.
Tested on a imx6q-udoo board and verified that it boots fine
and USB host functionality works.
