From: Ilya Ledvich <ilya@xxxxxxxxxxxxxx> Add basic support for CompuLab cm-t335 module based on AM335X SoC. CM-T335 is a tiny computer-on-module (CoM) / system-on-module (SoM) The module is built around the Texas Instruments Sitara AM3352/4 system-on-chip. The CPU is supplemented with up-to 512MB DDR3 and up-to 1GB of on-board NAND storage, WiFi connected to SPI, Bluetooth, Analog audio, Gigabit Ethernet, CAN bus. Current patch adds support: UART0 and GPIO LED Detailed description can be found at the module site: http://www.compulab.co.il/products/computer-on-modules/cm-t335/ Signed-off-by: Ilya Ledvich <ilya@xxxxxxxxxxxxxx> [uri.mashiach@xxxxxxxxxxxxxx: the default RAM amount reduced to 128MB to support also the minimal module configuration] Signed-off-by: Uri Mashiach <uri.mashiach@xxxxxxxxxxxxxx> Acked-by: Igor Grinberg <grinberg@xxxxxxxxxxxxxx> --- v1 -> v2: integrate AM33XX_IOPAD macro in pinmux definitions .../devicetree/bindings/arm/omap/omap.txt | 3 ++ arch/arm/boot/dts/Makefile | 7 +-- arch/arm/boot/dts/am335x-cm-t335.dts | 63 ++++++++++++++++++++++ 3 files changed, 70 insertions(+), 3 deletions(-) create mode 100644 arch/arm/boot/dts/am335x-cm-t335.dts diff --git a/Documentation/devicetree/bindings/arm/omap/omap.txt b/Documentation/devicetree/bindings/arm/omap/omap.txt index 9f4e513..2154f97 100644 --- a/Documentation/devicetree/bindings/arm/omap/omap.txt +++ b/Documentation/devicetree/bindings/arm/omap/omap.txt @@ -138,6 +138,9 @@ Boards: - AM335X phyBOARD-WEGA: Single Board Computer dev kit compatible = "phytec,am335x-wega", "phytec,am335x-phycore-som", "ti,am33xx" +- AM335X CM-T335 : System On Module, built around the Sitara AM3352/4 + compatible = "compulab,cm-t335", "ti,am33xx" + - OMAP5 EVM : Evaluation Module compatible = "ti,omap5-evm", "ti,omap5" diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index bb8fa02..0e011dc 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -446,13 +446,14 @@ dtb-$(CONFIG_SOC_AM33XX) += \ am335x-base0033.dtb \ am335x-bone.dtb \ am335x-boneblack.dtb \ - am335x-sl50.dtb \ + am335x-chiliboard.dtb \ + am335x-cm-t335.dtb \ am335x-evm.dtb \ am335x-evmsk.dtb \ + am335x-lxm.dtb \ am335x-nano.dtb \ am335x-pepper.dtb \ - am335x-lxm.dtb \ - am335x-chiliboard.dtb \ + am335x-sl50.dtb \ am335x-wega-rdk.dtb dtb-$(CONFIG_ARCH_OMAP4) += \ omap4-duovero-parlor.dtb \ diff --git a/arch/arm/boot/dts/am335x-cm-t335.dts b/arch/arm/boot/dts/am335x-cm-t335.dts new file mode 100644 index 0000000..719658e --- /dev/null +++ b/arch/arm/boot/dts/am335x-cm-t335.dts @@ -0,0 +1,63 @@ +/* + * am335x-cm-t335.dts - Device Tree file for Compulab CM-T335 + * + * Copyright (C) 2014 - 2015 CompuLab Ltd. - http://www.compulab.co.il/ + * + * 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" + +/ { + model = "CompuLab CM-T335"; + compatible = "compulab,cm-t335", "ti,am33xx"; + + memory { + device_type = "memory"; + reg = <0x80000000 0x8000000>; /* 128 MB */ + }; + + leds { + compatible = "gpio-leds"; + pinctrl-names = "default"; + pinctrl-0 = <&gpio_led_pins>; + led@0 { + label = "cm_t335:green"; + gpios = <&gpio2 0 GPIO_ACTIVE_LOW>; /* gpio2_0 */ + linux,default-trigger = "heartbeat"; + }; + }; +}; + +&am33xx_pinmux { + pinctrl-names = "default"; + pinctrl-0 = <>; + + gpio_led_pins: pinmux_gpio_led_pins { + pinctrl-single,pins = < + /* gpmc_csn3.gpio2_0 */ + AM33XX_IOPAD(0x888, PIN_OUTPUT | MUX_MODE7) + >; + }; + + uart0_pins: pinmux_uart0_pins { + pinctrl-single,pins = < + /* uart0_rxd.uart0_rxd */ + AM33XX_IOPAD(0x970, PIN_INPUT_PULLUP | MUX_MODE0) + /* uart0_txd.uart0_txd */ + AM33XX_IOPAD(0x974, PIN_OUTPUT_PULLDOWN | MUX_MODE0) + >; + }; +}; + +&uart0 { + pinctrl-names = "default"; + pinctrl-0 = <&uart0_pins>; + + status = "okay"; +}; + -- 2.5.0 -- 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
