Assign USB ports previously owned by the EHCI controllers to the xHCI controller. There is a mini-PCIe USB port (UTMI port 1) and a USB A connector (UTMI port 2, USB3 port 0). PCIe lane 0 is used for USB3 port 0. Signed-off-by: Andrew Bresticker <abrestic@xxxxxxxxxxxx> Reviewed-by: Stephen Warren <swarren@xxxxxxxxxx> --- No changes from v5. Changes from v4: - Updated regulator and pinconfig properties. Changes from v3: - Assigned otg-0 to XUSB to avoid USB2.0 flakiness. Changes from v2: - Updated VBUS power supply names. Changes from v1: - Updated USB power supplies. --- arch/arm/boot/dts/tegra124-jetson-tk1.dts | 46 +++++++++++++++++-------------- 1 file changed, 26 insertions(+), 20 deletions(-) diff --git a/arch/arm/boot/dts/tegra124-jetson-tk1.dts b/arch/arm/boot/dts/tegra124-jetson-tk1.dts index 51b373f..be93710 100644 --- a/arch/arm/boot/dts/tegra124-jetson-tk1.dts +++ b/arch/arm/boot/dts/tegra124-jetson-tk1.dts @@ -1687,15 +1687,40 @@ target-12v-supply = <&vdd_12v0_sata>; }; + usb@0,70090000 { + status = "okay"; + phys = <&padctl TEGRA_XUSB_PADCTL_UTMI_P1>, /* mini-PCIe USB */ + <&padctl TEGRA_XUSB_PADCTL_UTMI_P2>, /* USB A */ + <&padctl TEGRA_XUSB_PADCTL_USB3_P0>; /* USB A */ + phy-names = "utmi-1", "utmi-2", "usb3-0"; + avddio-pex-supply = <&vdd_1v05_run>; + dvddio-pex-supply = <&vdd_1v05_run>; + avdd-usb-supply = <&vdd_3v3_lp0>; + avdd-pll-utmip-supply = <&vddio_1v8>; + avdd-pll-erefe-supply = <&avdd_1v05_run>; + avdd-usb-ss-pll-supply = <&vdd_1v05_run>; + hvdd-usb-ss-supply = <&vdd_3v3_lp0>; + hvdd-usb-ss-pll-e-supply = <&vdd_3v3_lp0>; + }; + padctl@0,7009f000 { pinctrl-0 = <&padctl_default>; pinctrl-names = "default"; + vbus-2-supply = <&vdd_usb3_vbus>; + padctl_default: pinmux { + otg { + nvidia,lanes = "otg-0", "otg-1", "otg-2"; + nvidia,function = "xusb"; + }; + usb3 { - nvidia,lanes = "pcie-0", "pcie-1"; + nvidia,lanes = "pcie-0"; nvidia,function = "usb3"; nvidia,iddq = <0>; + nvidia,usb2-port = <2>; + nvidia,usb3-port = <0>; }; pcie { @@ -1736,25 +1761,6 @@ }; }; - /* mini-PCIe USB */ - usb@0,7d004000 { - status = "okay"; - }; - - usb-phy@0,7d004000 { - status = "okay"; - }; - - /* USB A connector */ - usb@0,7d008000 { - status = "okay"; - }; - - usb-phy@0,7d008000 { - status = "okay"; - vbus-supply = <&vdd_usb3_vbus>; - }; - clocks { compatible = "simple-bus"; #address-cells = <1>; -- 2.1.0.rc2.206.gedb03e5 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
