Well, turns out that part of the "Import device-tree files from Linux 5.14" is: = https://cgit.freebsd.org/src/commit/sys/contrib/device-tree/src/arm64/rock= chip/rk3328-rock64.dts?id=3D5956d97f4b32 which has: diff --git = a/sys/contrib/device-tree/src/arm64/rockchip/rk3328-rock64.dts = b/sys/contrib/device-tree/src/arm64/rockchip/rk3328-rock64.dts index 3bef1f39bc6e..1b0f7e4551ea 100644 --- a/sys/contrib/device-tree/src/arm64/rockchip/rk3328-rock64.dts +++ b/sys/contrib/device-tree/src/arm64/rockchip/rk3328-rock64.dts @@ -381,6 +381,11 @@ status =3D "okay"; }; =20 +&usbdrd3 { + dr_mode =3D "host"; + status =3D "okay"; +}; + &usb_host0_ehci { status =3D "okay"; }; usbdrd3 is for USB3, so "host" now has a sort of dtb change in the interfacing for supporting host-mode USB3. The old: /usr/main-src/sys/dts/arm64/overlays/rk3328-dwc3.dtso has, in part: usbdrd3: usb@ff600000 { compatible =3D "rockchip,rk3328-dwc3"; clocks =3D <&cru SCLK_USB3OTG_REF>, <&cru = SCLK_USB3OTG_SUSPEND>, <&cru ACLK_USB3OTG>; clock-names =3D "ref_clk", "suspend_clk", "bus_clk"; #address-cells =3D <2>; #size-cells =3D <2>; ranges; status =3D "okay"; usbdrd_dwc3: dwc3@ff600000 { compatible =3D "snps,dwc3"; reg =3D <0x0 0xff600000 0x0 0x100000>; interrupts =3D <GIC_SPI 67 IRQ_TYPE_LEVEL_HIGH>; dr_mode =3D "host"; phy_type =3D "utmi_wide"; snps,dis_enblslpm_quirk; snps,dis-u2-freeclk-exists-quirk; snps,dis_u2_susphy_quirk; snps,dis_u3_susphy_quirk; snps,dis-del-phy-power-chg-quirk; snps,dis-tx-ipgap-linecheck-quirk; status =3D "okay"; }; }; which looks to me to likely now conflict with the below --given the added "host" usage as of 5.14 reported above: /usr/main-src/sys/contrib/device-tree/src/arm64/rockchip/rk3328.dtsi that, as of the 5.13 import, has: usbdrd3: usb@ff600000 { compatible =3D "rockchip,rk3328-dwc3", "snps,dwc3"; reg =3D <0x0 0xff600000 0x0 0x100000>; interrupts =3D <GIC_SPI 67 IRQ_TYPE_LEVEL_HIGH>; clocks =3D <&cru SCLK_USB3OTG_REF>, <&cru = SCLK_USB3OTG_SUSPEND>, <&cru ACLK_USB3OTG>; clock-names =3D "ref_clk", "suspend_clk", "bus_clk"; dr_mode =3D "otg"; phy_type =3D "utmi_wide"; snps,dis-del-phy-power-chg-quirk; snps,dis_enblslpm_quirk; snps,dis-tx-ipgap-linecheck-quirk; snps,dis-u2-freeclk-exists-quirk; snps,dis_u2_susphy_quirk; snps,dis_u3_susphy_quirk; status =3D "disabled"; }; My guess would be that some kernel changes are required in order to track this structural changes, not just avoiding the old .dtbo . Testing showed that disabling the load of the .dtbo was insufficient to fix things. =3D=3D=3D Mark Millard marklmi at yahoo.com
