From af3c0380ebb1de0cd688a9e02d75da3cc79e43f6 Mon Sep 17 00:00:00 2001 From: Florian Vaussard Date: Fri, 7 Mar 2014 20:22:11 +0100 Subject: ARM: dts: overo: reorganize include files Currently, overo-related include files are organized as follow: omap3-overo.dtsi | | omap34xx.dtsi omap3-overo-tobi-common.dtsi omap36xx.dtsi | | | | --------------- --------------- | | omap3-overo-tobi.dts omap3-overo-storm-tobi.dts This is unpractical when one has to deal with SoC-specific pinmux belonging to the omap3_pmx_core2 (defined in omap34xx/omap36xx), for pins related to the processor board. With the current hierarchy, such pinmux has to be defined in the expansion board's .dts, which is not logical. This patches reorganizes the files to add (yet another) abstraction layer between the processor and the expansion boards. omap34xx.dtsi omap3-overo-base.dtsi omap36xx.dtsi | | | | --------------- --------------- | | omap3-overo.dtsi omap3-overo-storm.dtsi | | -------- ------ | omap3-overo-tobi-common.dtsi | | | | | --------------- --------------- | | omap3-overo-tobi.dts omap3-overo-storm-tobi.dts Signed-off-by: Florian Vaussard Signed-off-by: Tony Lindgren --- arch/arm/boot/dts/omap3-overo-base.dtsi | 94 +++++++++++++++++++++++++++++++++ 1 file changed, 94 insertions(+) create mode 100644 arch/arm/boot/dts/omap3-overo-base.dtsi (limited to 'arch/arm/boot/dts/omap3-overo-base.dtsi') diff --git a/arch/arm/boot/dts/omap3-overo-base.dtsi b/arch/arm/boot/dts/omap3-overo-base.dtsi new file mode 100644 index 000000000000..597099907f8e --- /dev/null +++ b/arch/arm/boot/dts/omap3-overo-base.dtsi @@ -0,0 +1,94 @@ +/* + * Copyright (C) 2012 Florian Vaussard, EPFL Mobots group + * + * 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. + */ + +/* + * The Gumstix Overo must be combined with an expansion board. + */ + +/ { + pwmleds { + compatible = "pwm-leds"; + + overo { + label = "overo:blue:COM"; + pwms = <&twl_pwmled 1 7812500>; + max-brightness = <127>; + linux,default-trigger = "mmc0"; + }; + }; + + sound { + compatible = "ti,omap-twl4030"; + ti,model = "overo"; + + ti,mcbsp = <&mcbsp2>; + ti,codec = <&twl_audio>; + }; +}; + +&i2c1 { + clock-frequency = <2600000>; + + twl: twl@48 { + reg = <0x48>; + interrupts = <7>; /* SYS_NIRQ cascaded to intc */ + interrupt-parent = <&intc>; + + twl_audio: audio { + compatible = "ti,twl4030-audio"; + codec { + }; + }; + }; +}; + +#include "twl4030.dtsi" +#include "twl4030_omap3.dtsi" + +/* i2c2 pins are used for gpio */ +&i2c2 { + status = "disabled"; +}; + +/* on board microSD slot */ +&mmc1 { + vmmc-supply = <&vmmc1>; + bus-width = <4>; +}; + +/* optional on board WiFi */ +&mmc2 { + bus-width = <4>; +}; + +&twl_gpio { + ti,use-leds; +}; + +&usb_otg_hs { + interface-type = <0>; + usb-phy = <&usb2_phy>; + phys = <&usb2_phy>; + phy-names = "usb2-phy"; + mode = <3>; + power = <50>; +}; + +&omap3_pmx_core { + uart3_pins: pinmux_uart3_pins { + pinctrl-single,pins = < + 0x16e (PIN_INPUT | PIN_OFF_WAKEUPENABLE | MUX_MODE0) /* uart3_rx_irrx.uart3_rx_irrx */ + 0x170 (PIN_OUTPUT | MUX_MODE0) /* uart3_tx_irtx.uart3_tx_irtx */ + >; + }; +}; + +&uart3 { + pinctrl-names = "default"; + pinctrl-0 = <&uart3_pins>; +}; -- cgit v1.2.1
