USB1 and USB3 are routed to two external connectors, while USB2 is used for the integrated webcam.
Signed-off-by: Thierry Reding <[email protected]> --- Note: connecting a USB mouse to USB3 works properly and lsusb also detects the integrated webcam, though I haven't tested whether the camera actually works. USB1 doesn't seem to work, but I suspect that might just be because it's used for recovery mode and we can't switch it around at runtime yet. --- arch/arm/boot/dts/tegra124-venice2.dts | 47 +++++++++++++++++++++++++++++++++- 1 file changed, 46 insertions(+), 1 deletion(-) diff --git a/arch/arm/boot/dts/tegra124-venice2.dts b/arch/arm/boot/dts/tegra124-venice2.dts index b770e903fabb..efdf93e6f5cc 100644 --- a/arch/arm/boot/dts/tegra124-venice2.dts +++ b/arch/arm/boot/dts/tegra124-venice2.dts @@ -534,7 +534,7 @@ ams,enable-tracking; }; - ldo4 { + cam_2v8_reg: ldo4 { regulator-name = "avdd_cam"; regulator-min-microvolt = <2800000>; regulator-max-microvolt = <2800000>; @@ -715,6 +715,33 @@ }; }; + usb@7d000000 { + status = "okay"; + }; + + usb-phy@7d000000 { + status = "okay"; + vbus-supply = <&usb1_vbus_reg>; + }; + + usb@7d004000 { + status = "okay"; + }; + + usb-phy@7d004000 { + status = "okay"; + vbus-supply = <&cam_2v8_reg>; + }; + + usb@7d008000 { + status = "okay"; + }; + + usb-phy@7d008000 { + status = "okay"; + vbus-supply = <&usb3_vbus_reg>; + }; + backlight: backlight { compatible = "pwm-backlight"; @@ -788,6 +815,24 @@ gpio = <&gpio TEGRA_GPIO(P, 2) 0 GPIO_ACTIVE_HIGH>; enable-active-high; }; + + usb1_vbus_reg: regulator@3 { + compatible = "regulator-fixed"; + reg = <3>; + regulator-name = "usb1_vbus"; + regulator-min-microvolt = <5000000>; + regulator-max-microvolt = <5000000>; + regulator-boot-on; + }; + + usb3_vbus_reg: regulator@4 { + compatible = "regulator-fixed"; + reg = <4>; + regulator-name = "usb3_vbus"; + regulator-min-microvolt = <5000000>; + regulator-max-microvolt = <5000000>; + regulator-boot-on; + }; }; sound { -- 1.8.4.2 -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
