Subject: [PATCH] usb: chipidea: imx: don't request QoS for imx8ulp
Git-commit: 9a070e8e208995a9d638b538ed7abf28bd6ea6f0
Patch-mainline: v6.5-rc1
References: git-fixes

Use dedicated imx8ulp usb compatible to remove QoS request
since imx8ulp has no such limitation of imx7ulp: DMA will
not work if system enters idle.
