Comment # 9 on bug 1199909 from Peng Fan

seems a phy driver is not under modules for phy-fsl-imx8mq-usb.o.

ttymxc0:install:/modules # cat /config | grep -i 8MQ
CONFIG_PINCTRL_IMX8MQ=y
CONFIG_CLK_IMX8MQ=y
CONFIG_PHY_FSL_IMX8MQ_USB=m
CONFIG_INTERCONNECT_IMX8MQ=m
ttymxc0:install:/modules # ls phy
phy-generic.ko.zst             phy-rockchip-dp.ko.zst        
phy-rockchip-typec.ko.zst      phy-xgene.ko.zst
phy-intel-keembay-emmc.ko.zst  phy-rockchip-emmc.ko.zst      
phy-tegra-usb.ko.zst           phylink.ko.zst
phy-intel-keembay-usb.ko.zst   phy-rockchip-inno-usb2.ko.zst 
phy-tegra-xusb.ko.zst
phy-mvebu-cp110-comphy.ko.zst  phy-rockchip-pcie.ko.zst      
phy-tegra194-p2u.ko.zst
ttymxc0:install:/modules # ls * | grep 8mq

the attached rc1 is RC1 log which has phy driver probed.
