BeagleBone Black Wireless is clone of the BeagleBone Black (BBB) with the Ethernet replaced by a TI wl1835 wireless module. This board can be indentified by the BWAx value after A335BNLT (BBB) in the at24 eeprom: BWAx [aa 55 33 ee 41 33 33 35 42 4e 4c 54 42 57 41 35 |.U3.A335BNLTBWA5|] http://beagleboard.org/black-wireless https://github.com/beagleboard/beaglebone-black-wireless firmware: https://github.com/beagleboard/beaglebone-black-wireless/tree/master/firmware wl18xx mac address: /proc/device-tree/ocp/ethernet@4a100000/slave@4a100200/mac-address Signed-off-by: Robert Nelson <robertcnelson@xxxxxxxxx> CC: Tony Lindgren <tony@xxxxxxxxxxx> CC: Jason Kridner <jkridner@xxxxxxxxxxxxxxx> --- arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/am335x-boneblack-wireless.dts | 109 ++++++++++++++++++++++++ 2 files changed, 110 insertions(+) create mode 100644 arch/arm/boot/dts/am335x-boneblack-wireless.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index cccdbcb557b6..9415a49bd11b 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -563,6 +563,7 @@ dtb-$(CONFIG_SOC_AM33XX) += \ am335x-base0033.dtb \ am335x-bone.dtb \ am335x-boneblack.dtb \ + am335x-boneblack-wireless.dtb \ am335x-bonegreen.dtb \ am335x-chiliboard.dtb \ am335x-cm-t335.dtb \ diff --git a/arch/arm/boot/dts/am335x-boneblack-wireless.dts b/arch/arm/boot/dts/am335x-boneblack-wireless.dts new file mode 100644 index 000000000000..105bd10655f7 --- /dev/null +++ b/arch/arm/boot/dts/am335x-boneblack-wireless.dts @@ -0,0 +1,109 @@ +/* + * Copyright (C) 2012 Texas Instruments Incorporated - http://www.ti.com/ + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + */ +/dts-v1/; + +#include "am33xx.dtsi" +#include "am335x-bone-common.dtsi" +#include "am335x-boneblack-common.dtsi" +#include <dt-bindings/interrupt-controller/irq.h> + +/ { + model = "TI AM335x BeagleBone Black Wireless"; + compatible = "ti,am335x-bone-black-wireless", "ti,am335x-bone-black", "ti,am335x-bone", "ti,am33xx"; + + wlan_en_reg: fixedregulator@2 { + compatible = "regulator-fixed"; + regulator-name = "wlan-en-regulator"; + regulator-min-microvolt = <1800000>; + regulator-max-microvolt = <1800000>; + startup-delay-us= <70000>; + + /* WL_EN */ + gpio = <&gpio3 9 0>; + enable-active-high; + }; +}; + +&am33xx_pinmux { + bt_pins: pinmux_bt_pins { + pinctrl-single,pins = < + AM33XX_IOPAD(0x928, PIN_OUTPUT_PULLUP | MUX_MODE7) /* gmii1_txd0.gpio0_28 - BT_EN */ + >; + }; + + mmc3_pins: pinmux_mmc3_pins { + pinctrl-single,pins = < + AM33XX_IOPAD(0x93c, PIN_INPUT_PULLUP | MUX_MODE6 ) /* (L15) gmii1_rxd1.mmc2_clk */ + AM33XX_IOPAD(0x914, PIN_INPUT_PULLUP | MUX_MODE6 ) /* (J16) gmii1_txen.mmc2_cmd */ + AM33XX_IOPAD(0x918, PIN_INPUT_PULLUP | MUX_MODE5 ) /* (J17) gmii1_rxdv.mmc2_dat0 */ + AM33XX_IOPAD(0x91c, PIN_INPUT_PULLUP | MUX_MODE5 ) /* (J18) gmii1_txd3.mmc2_dat1 */ + AM33XX_IOPAD(0x920, PIN_INPUT_PULLUP | MUX_MODE5 ) /* (K15) gmii1_txd2.mmc2_dat2 */ + AM33XX_IOPAD(0x908, PIN_INPUT_PULLUP | MUX_MODE5 ) /* (H16) gmii1_col.mmc2_dat3 */ + >; + }; + + uart3_pins: pinmux_uart3_pins { + pinctrl-single,pins = < + AM33XX_IOPAD(0x934, PIN_INPUT_PULLUP | MUX_MODE1) /* gmii1_rxd3.uart3_rxd */ + AM33XX_IOPAD(0x938, PIN_OUTPUT_PULLDOWN | MUX_MODE1) /* gmii1_rxd2.uart3_txd */ + AM33XX_IOPAD(0x948, PIN_INPUT | MUX_MODE3) /* mdio_data.uart3_ctsn */ + AM33XX_IOPAD(0x94c, PIN_OUTPUT_PULLDOWN | MUX_MODE3) /* mdio_clk.uart3_rtsn */ + >; + }; + + wl18xx_pins: pinmux_wl18xx_pins { + pinctrl-single,pins = < + AM33XX_IOPAD(0x92c, PIN_OUTPUT_PULLDOWN | MUX_MODE7) /* gmii1_txclk.gpio3_9 WL_EN */ + AM33XX_IOPAD(0x944, PIN_INPUT_PULLDOWN | MUX_MODE7) /* rmii1_refclk.gpio0_29 WL_IRQ */ + AM33XX_IOPAD(0x930, PIN_OUTPUT_PULLUP | MUX_MODE7) /* gmii1_rxclk.gpio3_10 LS_BUF_EN */ + >; + }; +}; + +&mac { + status = "disabled"; +}; + +&mmc3 { + dmas = <&edma_xbar 12 0 1 + &edma_xbar 13 0 2>; + dma-names = "tx", "rx"; + status = "okay"; + vmmc-supply = <&wlan_en_reg>; + bus-width = <4>; + non-removable; + cap-power-off-card; + ti,needs-special-hs-handling; + keep-power-in-suspend; + pinctrl-names = "default"; + pinctrl-0 = <&mmc3_pins &wl18xx_pins>; + + #address-cells = <1>; + #size-cells = <0>; + wlcore: wlcore@2 { + compatible = "ti,wl1835"; + reg = <2>; + interrupt-parent = <&gpio0>; + interrupts = <29 IRQ_TYPE_EDGE_RISING>; + }; +}; + +&uart3 { + pinctrl-names = "default"; + pinctrl-0 = <&uart3_pins &bt_pins>; + status = "okay"; +}; + +&gpio3 { + ls_buf_en { + gpio-hog; + gpios = <10 GPIO_ACTIVE_HIGH>; + output-high; + line-name = "LS_BUF_EN"; + }; +}; -- 2.11.0 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
