There are two external USB ports (UTMI ports 0/2 and USB3 ports 0/1) and an internal USB port (UTMI port 1). PCIe lanes 0 and 1 are used by the USB3 ports. Signed-off-by: Andrew Bresticker <abrestic@...omium.org> Reviewed-by: Stephen Warren <swarren@...dia.com> --- Changes from v4: - Updated regulator and pinconfig properties. No changes from v3. Changes from v2: - Updated VBUS power supply names. Changes from v1: - Updated USB power supplies. --- arch/arm/boot/dts/tegra124-venice2.dts | 79 ++++++++++++++++++++++------------ 1 file changed, 51 insertions(+), 28 deletions(-) diff --git a/arch/arm/boot/dts/tegra124-venice2.dts b/arch/arm/boot/dts/tegra124-venice2.dts index 1300885..24a8bb8 100644 --- a/arch/arm/boot/dts/tegra124-venice2.dts +++ b/arch/arm/boot/dts/tegra124-venice2.dts @@ -744,7 +744,7 @@ regulator-always-on; }; - ldo0 { + avdd_1v05_run: ldo0 { regulator-name = "+1.05V_RUN_AVDD"; regulator-min-microvolt = <1050000>; regulator-max-microvolt = <1050000>; @@ -886,6 +886,56 @@ status = "okay"; }; + usb@0,70090000 { + status = "okay"; + phys = <&padctl TEGRA_XUSB_PADCTL_UTMI_P0>, /* 1st USB A */ + <&padctl TEGRA_XUSB_PADCTL_UTMI_P1>, /* Internal USB */ + <&padctl TEGRA_XUSB_PADCTL_UTMI_P2>, /* 2nd USB A */ + <&padctl TEGRA_XUSB_PADCTL_USB3_P0>, /* 1st USB A */ + <&padctl TEGRA_XUSB_PADCTL_USB3_P1>; /* 2nd USB A */ + phy-names = "utmi-0", "utmi-1", "utmi-2", "usb3-0", "usb3-1"; + 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-0-supply = <&vdd_usb1_vbus>; + vbus-1-supply = <&vdd_run_cam>; + vbus-2-supply = <&vdd_usb3_vbus>; + + padctl_default: pinmux { + otg { + nvidia,lanes = "otg-0", "otg-1", "otg-2"; + nvidia,function = "xusb"; + }; + + usb3p0 { + nvidia,lanes = "pcie-0"; + nvidia,function = "usb3"; + nvidia,iddq = <0>; + nvidia,usb2-port = <0>; + nvidia,usb3-port = <0>; + }; + + usb3p1 { + nvidia,lanes = "pcie-1"; + nvidia,function = "usb3"; + nvidia,iddq = <0>; + nvidia,usb2-port = <2>; + nvidia,usb3-port = <1>; + }; + }; + }; + sdhci@0,700b0400 { cd-gpios = <&gpio TEGRA_GPIO(V, 2) GPIO_ACTIVE_HIGH>; power-gpios = <&gpio TEGRA_GPIO(R, 0) GPIO_ACTIVE_HIGH>; @@ -906,33 +956,6 @@ }; }; - usb@0,7d000000 { - status = "okay"; - }; - - usb-phy@0,7d000000 { - status = "okay"; - vbus-supply = <&vdd_usb1_vbus>; - }; - - usb@0,7d004000 { - status = "okay"; - }; - - usb-phy@0,7d004000 { - status = "okay"; - vbus-supply = <&vdd_run_cam>; - }; - - usb@0,7d008000 { - status = "okay"; - }; - - usb-phy@0,7d008000 { - status = "okay"; - vbus-supply = <&vdd_usb3_vbus>; - }; - backlight: backlight { compatible = "pwm-backlight"; -- 2.1.0.rc2.206.gedb03e5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
