From dc929d49dce577149157f0676973e5eafbbdc098 Mon Sep 17 00:00:00 2001 From: Anand Moon Date: Sun, 7 Jun 2015 21:23:47 +0930 Subject: [PATCH] ARM: dts: Enable USB3 regulators for exynos5422-odroidxu3 Enable regulator for usbdrd3_0 and usbdrd3_1. Looking at the schematic pin diagram for MAX77802 USB3_0 and USB3_1 is regulated by LDO9 and LD011. This removes following warnings during boot: [ 3.503539] exynos-dwc3 usb@12000000: Looking up vdd33-supply from device tree [ 3.503556] exynos-dwc3 usb@12000000: Looking up vdd33-supply property in node /usb@12000000 failed [ 3.503568] usb@12000000 supply vdd33 not found, using dummy regulator [ 3.509154] exynos-dwc3 usb@12000000: Looking up vdd10-supply from device tree [ 3.509170] exynos-dwc3 usb@12000000: Looking up vdd10-supply property in node /usb@12000000 failed [ 3.509181] usb@12000000 supply vdd10 not found, using dummy regulator [ 3.917548] exynos-dwc3 usb@12400000: Looking up vdd33-supply from device tree [ 3.917565] exynos-dwc3 usb@12400000: Looking up vdd33-supply property in node /usb@12400000 failed [ 3.917578] usb@12400000 supply vdd33 not found, using dummy regulator [ 3.922731] exynos-dwc3 usb@12400000: Looking up vdd10-supply from device tree [ 3.922747] exynos-dwc3 usb@12400000: Looking up vdd10-supply property in node /usb@12400000 failed Signed-off-by: Anand Moon Tested-by: Krzysztof Kozlowski Signed-off-by: Krzysztof Kozlowski Signed-off-by: Kukjin Kim --- arch/arm/boot/dts/exynos5422-odroidxu3-common.dtsi | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/arch/arm/boot/dts/exynos5422-odroidxu3-common.dtsi b/arch/arm/boot/dts/exynos5422-odroidxu3-common.dtsi index 8adf455744e9..deb8d78dff02 100644 --- a/arch/arm/boot/dts/exynos5422-odroidxu3-common.dtsi +++ b/arch/arm/boot/dts/exynos5422-odroidxu3-common.dtsi @@ -477,3 +477,13 @@ &usbdrd_dwc3_1 { dr_mode = "otg"; }; + +&usbdrd3_0 { + vdd33-supply = <&ldo9_reg>; + vdd10-supply = <&ldo11_reg>; +}; + +&usbdrd3_1 { + vdd33-supply = <&ldo9_reg>; + vdd10-supply = <&ldo11_reg>; +}; -- 2.39.5
