TDA2HG: How to force usb as full-speed.

Part Number: TDA2HG

Hi,

My dts:

			usb@488d0000 {
				compatible = "snps,dwc3";
				reg = <0x488d0000 0x17000>;
				interrupts = <0x0 0x49 0x4 0x0 0x49 0x4 0x0 0x57 0x4>;
				interrupt-names = "peripheral", "host", "otg";
				phys = <0xd8>;
				phy-names = "usb2-phy";
				maximum-speed = "full-speed";
				dr_mode = "host";
				snps,dis_u3_susphy_quirk;
				snps,dis_u2_susphy_quirk;
				snps,dis_metastability_quirk;
			};

But when I execute "dmesg|grep usb" I got :

[   11.809245] usb usb2: We don't know the algorithms for LPM for this host, disabling LPM.
[   11.817716] usb usb2: New USB device found, idVendor=1d6b, idProduct=0003, bcdDevice= 4.19

It still show as "high-speed".

so, is there anything I missed?

Thanks!
