Unfortunately this results in USB not working on exynos5420-peach-pit and exynos5800-peach-pi with such a kernel configuration unless manually change the mode. To resolve that explicitly configure the dual role mode as host Signed-off-by: Sjoerd Simons Reviewed-by: Andreas Färber --- Changes in v2: alphabetically sort the dts entries Changes in v3: Fix typo in commit message Changes in v4: Rebased on linux-samsung for-next arch/arm/boot/dts/exynos5420-peach-pit.dts | 8 ++++++++ arch/arm/boot/dts/exynos5420.dtsi | 4 ++-- arch/arm/boot/dts/exynos5800-peach-pi.dts | 8 ++++++++ 3 files changed, 18 insertions(+), 2 deletions(-) diff --git a/arch/arm/boot/dts/exynos5420-peach-pit.dts b/arch/arm/boot/dts/exynos5420-peach-pit.dts index 17dae508..9a050e1 100644 --- a/arch/arm/boot/dts/exynos5420-peach-pit.dts +++ b/arch/arm/boot/dts/exynos5420-peach-pit.dts @@ -841,6 +841,14 @@ status = "okay"; }; +&usbdrd_dwc3_0 { + dr_mode = "host"; +}; + +&usbdrd_dwc3_1 { + dr_mode = "host"; +}; + &usbdrd_phy0 { vbus-supply = <&usb300_vbus_reg>; }; diff --git a/arch/arm/boot/dts/exynos5420.dtsi b/arch/arm/boot/dts/exynos5420.dtsi index bfe056d..8617a03 100644 --- a/arch/arm/boot/dts/exynos5420.dtsi +++ b/arch/arm/boot/dts/exynos5420.dtsi @@ -815,7 +815,7 @@ #size-cells = <1>; ranges; - dwc3 { + usbdrd_dwc3_0: dwc3 { compatible = "snps,dwc3"; reg = <0x12000000 0x10000>; interrupts = <0 72 0>; @@ -841,7 +841,7 @@ #size-cells = <1>; ranges; - dwc3 { + usbdrd_dwc3_1: dwc3 { compatible = "snps,dwc3"; reg = <0x12400000 0x10000>; interrupts = <0 73 0>; diff --git a/arch/arm/boot/dts/exynos5800-peach-pi.dts b/arch/arm/boot/dts/exynos5800-peach-pi.dts index 4d1492e..e8fdda8 100644 --- a/arch/arm/boot/dts/exynos5800-peach-pi.dts +++ b/arch/arm/boot/dts/exynos5800-peach-pi.dts @@ -829,6 +829,14 @@ status = "okay"; }; +&usbdrd_dwc3_0 { + dr_mode = "host"; +}; + +&usbdrd_dwc3_1 { + dr_mode = "host"; +}; + &usbdrd_phy0 { vbus-supply = <&usb300_vbus_reg>; };
