From mboxrd@z Thu Jan 1 00:00:00 1970 From: wens@csie.org (Chen-Yu Tsai) Date: Tue, 4 Nov 2014 12:07:19 +0800 Subject: [PATCH 6/6] ARM: dts: sun9i: Enable USB support on A80 Optimus board In-Reply-To: <1415074039-16590-1-git-send-email-wens@csie.org> References: <1415074039-16590-1-git-send-email-wens@csie.org> Message-ID: <1415074039-16590-7-git-send-email-wens@csie.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Signed-off-by: Chen-Yu Tsai --- This patch does not use sunxi-common-regulators.dtsi, but adds the regulators directly. To use the common regulators file, we would need to use phandles and switch to preprocessor includes to support that. --- arch/arm/boot/dts/sun9i-a80-optimus.dts | 72 +++++++++++++++++++++++++++++++++ 1 file changed, 72 insertions(+) diff --git a/arch/arm/boot/dts/sun9i-a80-optimus.dts b/arch/arm/boot/dts/sun9i-a80-optimus.dts index 506948f..31010c1 100644 --- a/arch/arm/boot/dts/sun9i-a80-optimus.dts +++ b/arch/arm/boot/dts/sun9i-a80-optimus.dts @@ -59,6 +59,40 @@ }; soc { + ehci0: usb at 00a00000 { + status = "okay"; + }; + + ohci0: usb at 00a00400 { + status = "okay"; + }; + + usbphy0: phy at 00a00800 { + vbus-supply = <®_usb0_vbus>; + status = "okay"; + }; + + ehci1: usb at 00a01000 { + status = "okay"; + }; + + usbphy1: phy at 00a01800 { + status = "okay"; + }; + + ehci2: usb at 00a02000 { + status = "okay"; + }; + + ohci2: usb at 00a02400 { + status = "okay"; + }; + + usbphy2: phy at 00a02800 { + vbus-supply = <®_usb2_vbus>; + status = "okay"; + }; + pio: pinctrl at 06000800 { i2c3_pins_a: i2c3 at 0 { /* Enable internal pull-up */ @@ -76,6 +110,20 @@ /* Enable internal pull-up */ allwinner,pull = <1>; }; + + usb0_vbus_pin_optimus: usb0_vbus_pin at 1 { + allwinner,pins = "PH4"; + allwinner,function = "gpio_out"; + allwinner,drive = <0>; + allwinner,pull = <0>; + }; + + usb2_vbus_pin_optimus: usb2_vbus_pin at 1 { + allwinner,pins = "PH5"; + allwinner,function = "gpio_out"; + allwinner,drive = <0>; + allwinner,pull = <0>; + }; }; uart0: serial at 07000000 { @@ -116,4 +164,28 @@ gpios = <&pio 7 0 0>; }; }; + + reg_usb0_vbus: usb0-vbus { + compatible = "regulator-fixed"; + pinctrl-names = "default"; + pinctrl-0 = <&usb0_vbus_pin_optimus>; + regulator-name = "usb0-vbus"; + regulator-min-microvolt = <5000000>; + regulator-max-microvolt = <5000000>; + enable-active-high; + gpio = <&pio 7 4 0>; /* PH4 */ + status = "okay"; + }; + + reg_usb2_vbus: usb2-vbus { + compatible = "regulator-fixed"; + pinctrl-names = "default"; + pinctrl-0 = <&usb2_vbus_pin_optimus>; + regulator-name = "usb2-vbus"; + regulator-min-microvolt = <5000000>; + regulator-max-microvolt = <5000000>; + enable-active-high; + gpio = <&pio 7 5 0>; /* PH5 */ + status = "okay"; + }; }; -- 2.1.1
