The usb2-phy projected here is actually the UTMI+ phy which is present as a part of a hybrid PHY controller (that includes both UTMI+ as well as PIPE3 phys). And the exynos5-usbdrd phy driver also differentiates between the two PHYs. It does try to separate out the initializations for UTMI+ and PIPE3 phy, if you notice the functions: exynos5_usbdrd_utmi_init() and exynos5_usbdrd_pipe3_init(). I don't think this change seems valid. > > Signed-off-by: Jaewon Kim <jaewon02.kim@xxxxxxxxxxx> > --- > arch/arm/boot/dts/exynos5250.dtsi | 4 ++-- > arch/arm/boot/dts/exynos5420.dtsi | 8 ++++---- > 2 files changed, 6 insertions(+), 6 deletions(-) > > diff --git a/arch/arm/boot/dts/exynos5250.dtsi b/arch/arm/boot/dts/exynos5250.dtsi > index 9bb1b0b..b58b169 100644 > --- a/arch/arm/boot/dts/exynos5250.dtsi > +++ b/arch/arm/boot/dts/exynos5250.dtsi > @@ -565,8 +565,8 @@ > compatible = "synopsys,dwc3"; > reg = <0x12000000 0x10000>; > interrupts = <0 72 0>; > - phys = <&usbdrd_phy 0>, <&usbdrd_phy 1>; > - phy-names = "usb2-phy", "usb3-phy"; > + phys = <&usbdrd_phy 0>; > + phy-names = "usb3-phy"; > }; > }; > > diff --git a/arch/arm/boot/dts/exynos5420.dtsi b/arch/arm/boot/dts/exynos5420.dtsi > index 9dc2e97..0df14bb 100644 > --- a/arch/arm/boot/dts/exynos5420.dtsi > +++ b/arch/arm/boot/dts/exynos5420.dtsi > @@ -845,8 +845,8 @@ > compatible = "snps,dwc3"; > reg = <0x12000000 0x10000>; > interrupts = <0 72 0>; > - phys = <&usbdrd_phy0 0>, <&usbdrd_phy0 1>; > - phy-names = "usb2-phy", "usb3-phy"; > + phys = <&usbdrd_phy0 0>; > + phy-names = "usb3-phy"; > }; > }; > > @@ -871,8 +871,8 @@ > compatible = "snps,dwc3"; > reg = <0x12400000 0x10000>; > interrupts = <0 73 0>; > - phys = <&usbdrd_phy1 0>, <&usbdrd_phy1 1>; > - phy-names = "usb2-phy", "usb3-phy"; > + phys = <&usbdrd_phy1 1>; > + phy-names = "usb3-phy"; > }; > }; > > -- > 1.7.9.5 > > -- > To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- Best Regards Vivek Gautam Samsung R&D Institute, Bangalore India -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
