This commit adds an include file for this, +avoiding the need to copy and paste the dts code. + +For sun5i-a13 based board the reference design uses a gpio on the pmic, which +we don't support yet. Still for consistency with all the other dts files also +add a sun5i-a13-usb-vbus-reg.dtsi files, without a gpio reference for now. + +Signed-off-by: Hans de Goede <hdegoede@redhat.com> +--- + arch/arm/boot/dts/sun5i-a10s-usb-vbus-reg.dtsi | 36 ++++++++++++++++++++++++++ + arch/arm/boot/dts/sun5i-a13-usb-vbus-reg.dtsi | 23 ++++++++++++++++ + 2 files changed, 59 insertions(+) + create mode 100644 arch/arm/boot/dts/sun5i-a10s-usb-vbus-reg.dtsi + create mode 100644 arch/arm/boot/dts/sun5i-a13-usb-vbus-reg.dtsi + +diff --git a/arch/arm/boot/dts/sun5i-a10s-usb-vbus-reg.dtsi b/arch/arm/boot/dts/sun5i-a10s-usb-vbus-reg.dtsi +new file mode 100644 +index 0000000..bb1a693 +--- /dev/null ++++ b/arch/arm/boot/dts/sun5i-a10s-usb-vbus-reg.dtsi +@@ -0,0 +1,36 @@ ++/* ++ * sun5i a10s boards usb vbus supply common code ++ * ++ * Copyright 2014 - Hans de Goede <hdegoede@redhat.com> ++ * ++ * The code contained herein is licensed under the GNU General Public ++ * License.
