Add support for Moxa UC-2101 open platform The UC-2101 computing platform is designed for industrial embedded data acquisition and processing applications. The features of UC-2101 are: * eMMC * SPI flash * 1x LAN * 1x RS-232/422/485 ports, software-selectable * EEPROM * TPM 2.0 * Watchdog * RTC * User gpio-keys * User LEDs * User button Signed-off-by: Wes Huang (黃淵河) <wes.huang@xxxxxxxx> Signed-off-by: Fero JD Zhou (周俊達) <FeroJD.Zhou@xxxxxxxx> Signed-off-by: SZ Lin (林上智) <sz.lin@xxxxxxxx> --- .../devicetree/bindings/arm/omap/omap.txt | 3 + arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/am335x-moxa-uc-2101.dts | 63 +++++++++++++++++++ 3 files changed, 67 insertions(+) create mode 100644 arch/arm/boot/dts/am335x-moxa-uc-2101.dts diff --git a/Documentation/devicetree/bindings/arm/omap/omap.txt b/Documentation/devicetree/bindings/arm/omap/omap.txt index 2ecc712bf707..c5ca3d6a8099 100644 --- a/Documentation/devicetree/bindings/arm/omap/omap.txt +++ b/Documentation/devicetree/bindings/arm/omap/omap.txt @@ -157,6 +157,9 @@ Boards: - AM335X phyCORE-AM335x: Development kit compatible = "phytec,am335x-pcm-953", "phytec,am335x-phycore-som", "ti,am33xx" +- AM335X UC-2100: Wireless-enabled palm-sized industrial computing platform + compatible = "moxa,uc-2101", "ti,am33xx" + - AM335X UC-8100-ME-T: Communication-centric industrial computing platform compatible = "moxa,uc-8100-me-t", "ti,am33xx"; diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index b5bd3de87c33..6167c068601c 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -706,6 +706,7 @@ dtb-$(CONFIG_SOC_AM33XX) += \ am335x-evmsk.dtb \ am335x-icev2.dtb \ am335x-lxm.dtb \ + am335x-moxa-uc-2101.dtb \ am335x-moxa-uc-8100-me-t.dtb \ am335x-nano.dtb \ am335x-pdu001.dtb \ diff --git a/arch/arm/boot/dts/am335x-moxa-uc-2101.dts b/arch/arm/boot/dts/am335x-moxa-uc-2101.dts new file mode 100644 index 000000000000..d0c1eea4a6c9 --- /dev/null +++ b/arch/arm/boot/dts/am335x-moxa-uc-2101.dts @@ -0,0 +1,63 @@ +// SPDX-License-Identifier: GPL-2.0 +/* + * Copyright (C) 2018 MOXA Inc. - https://www.moxa.com/ + * + * Authors: SZ Lin (林上智) <sz.lin@xxxxxxxx> + * Wes Huang (黃淵河) <wes.huang@xxxxxxxx> + * Fero JD Zhou (周俊達) <FeroJD.Zhou@xxxxxxxx> + */ + +/dts-v1/; + +#include "am335x-moxa-uc-2100-common.dtsi" + +/ { + model = "Moxa UC-2101"; + compatible = "moxa,uc-2101", "ti,am33xx"; + + leds { + compatible = "gpio-leds"; + led1 { + label = "UC2100:GREEN:USER"; + gpios = <&gpio3 10 GPIO_ACTIVE_HIGH>; + default-state = "off"; + }; + }; +}; + +&am33xx_pinmux { + pinctrl-names = "default"; + + cpsw_default: cpsw_default { + pinctrl-single,pins = < + /* Slave 1 */ + AM33XX_IOPAD(0x90c, PIN_INPUT_PULLDOWN | MUX_MODE1) /* mii1_crs.rmii1_crs_dv */ + AM33XX_IOPAD(0x910, PIN_INPUT_PULLUP | MUX_MODE1) /* mii1_rxerr.rmii1_rxerr */ + AM33XX_IOPAD(0x914, PIN_OUTPUT_PULLDOWN | MUX_MODE1) /* mii1_txen.rmii1_txen */ + AM33XX_IOPAD(0x924, PIN_OUTPUT_PULLDOWN | MUX_MODE1) /* mii1_txd1.rmii1_txd1 */ + AM33XX_IOPAD(0x928, PIN_OUTPUT_PULLDOWN | MUX_MODE1) /* mii1_txd0.rmii1_txd0 */ + AM33XX_IOPAD(0x93c, PIN_INPUT_PULLUP | MUX_MODE1) /* mii1_rxd1.rmii1_rxd1 */ + AM33XX_IOPAD(0x940, PIN_INPUT_PULLUP | MUX_MODE1) /* mii1_rxd0.rmii1_rxd0 */ + AM33XX_IOPAD(0x944, PIN_INPUT_PULLDOWN | MUX_MODE0) /* mii1_refclk.rmii1_refclk */ + >; + }; + + spi1_pins: pinmux_spi1 { + pinctrl-single,pins = < + AM33XX_IOPAD(0x964, PIN_INPUT_PULLUP | MUX_MODE4) /* ecap0_in_pwm0_out.spi1_sclk */ + AM33XX_IOPAD(0x978, PIN_INPUT_PULLUP | MUX_MODE4) /* uart1_ctsn.spi1_cs0 */ + AM33XX_IOPAD(0x968, PIN_INPUT_PULLUP | MUX_MODE4) /* uart0_ctsn.spi1_d0 */ + AM33XX_IOPAD(0x96c, PIN_INPUT_PULLUP | MUX_MODE4) /* uart0_rtsn.spi1_d1 */ + >; + }; +}; + +&cpsw_emac0 { + status = "okay"; + phy_id = <&davinci_mdio>, <0x4>; + phy-mode = "rmii"; +}; + +&cpsw_emac1 { + status = "disable"; +}; -- 2.19.0.rc1
