Signed-off-by: Maxime Ripard [wens@csie.org: enable usbphy, ehci0, ohci0 for on-board usb hub; add pcf8563 rtc node; add comments for i2c0 and mmc0 pull-ups; correct ethernet phy address to 0x01; drop uart2 (BT chip has no power) and uart3 (no device); use proper commit message] Signed-off-by: Chen-Yu Tsai --- arch/arm/boot/dts/sun6i-a31-hummingbird.dts | 119 ++++++++++++++++++++++++++++ 1 file changed, 119 insertions(+) create mode 100644 arch/arm/boot/dts/sun6i-a31-hummingbird.dts (limited to 'arch/arm/boot/dts/sun6i-a31-hummingbird.dts') diff --git a/arch/arm/boot/dts/sun6i-a31-hummingbird.dts b/arch/arm/boot/dts/sun6i-a31-hummingbird.dts new file mode 100644 index 000000000000..f142065b3c1f --- /dev/null +++ b/arch/arm/boot/dts/sun6i-a31-hummingbird.dts @@ -0,0 +1,119 @@ +/* + * Copyright 2014 Maxime Ripard + * + * Maxime Ripard + * + * The code contained herein is licensed under the GNU General Public + * License.
