No partition info yet configured though. Also looks like the PULL_ENA bit is inverted on dm816x like on am33xx so at some point we probably want to have a arch/arm/boot/dts/include/dt-bindings/pinctrl/dm816x.h. Regards, Tony 8< ------------- From: Tony Lindgren <tony@xxxxxxxxxxx> Date: Wed, 14 Jan 2015 17:45:22 -0800 Subject: [PATCH] ARM: dts: Add minimal support for dm8168-evm This allows booting the device with basic functionality. Note that at least on my revision c board the DDR3 does not seem to work properly and only some of the memory can be reliably used. Also, the mainline u-boot does not seem to properly initialize the ethernet, so I've been using the old TI u-boot at: http://arago-project.org/git/projects/?p=u-boot-omap3.git;a=summary Cc: Brian Hutchinson <b.hutchman@xxxxxxxxx> Signed-off-by: Tony Lindgren <tony@xxxxxxxxxxx> --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -348,6 +348,7 @@ dtb-$(CONFIG_ARCH_OMAP3) += am3517-craneboard.dtb \ omap3-sbc-t3730.dtb \ omap3-thunder.dtb \ omap3-zoom3.dtb +dtb-$(CONFIG_SOC_TI81XX) += dm8168-evm.dtb dtb-$(CONFIG_SOC_AM33XX) += am335x-base0033.dtb \ am335x-bone.dtb \ am335x-boneblack.dtb \ diff --git a/arch/arm/boot/dts/dm8168-evm.dts b/arch/arm/boot/dts/dm8168-evm.dts new file mode 100644 index 0000000..857d028 --- /dev/null +++ b/arch/arm/boot/dts/dm8168-evm.dts @@ -0,0 +1,129 @@ +/* + * 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 "dm816x.dtsi" + +/ { + model = "DM8168 EVM"; + compatible = "ti,dm8168-evm", "ti,dm8168"; + + memory { + device_type = "memory"; + reg = <0x80000000 0x40000000 /* 1 GB */ + 0xc0000000 0x40000000>; /* 1 GB */ + }; + + /* FDC6331L controlled by SD_POW pin */ + vmmcsd_fixed: fixedregulator@0 { + compatible = "regulator-fixed"; + regulator-name = "vmmcsd_fixed"; + regulator-min-microvolt = <3300000>; + regulator-max-microvolt = <3300000>; + }; +}; + +&dm816x_pinmux { + mcspi1_pins: pinmux_mcspi1_pins { + pinctrl-single,pins = < + DM816X_IOPAD(0x0a94, PIN_INPUT | MUX_MODE0) /* SPI_SCLK */ + DM816X_IOPAD(0x0a98, PIN_OUTPUT | MUX_MODE0) /* SPI_SCS0 */ + DM816X_IOPAD(0x0aa8, PIN_INPUT | MUX_MODE0) /* SPI_D0 */ + DM816X_IOPAD(0x0aac, PIN_INPUT | MUX_MODE0) /* SPI_D1 */ + >; + }; +}; + +&i2c1 { + extgpio0: pcf8575@20 { + compatible = "nxp,pcf8575"; + reg = <0x20>; + gpio-controller; + #gpio-cells = <2>; + }; +}; + +&i2c2 { + extgpio1: pcf8575@20 { + compatible = "nxp,pcf8575"; + reg = <0x20>; + gpio-controller; + #gpio-cells = <2>; + }; +}; + +&gpmc { + ranges = <0 0 0x04000000 0x01000000>; /* CS0: 16MB for NAND */ + + nand@0,0 { + linux,mtd-name= "micron,mt29f2g16aadwp"; + reg = <0 0 4>; /* CS0, offset 0, IO size 4 */ + #address-cells = <1>; + #size-cells = <1>; + ti,nand-ecc-opt = "bch8"; + nand-bus-width = <16>; + gpmc,device-width = <2>; + gpmc,sync-clk-ps = <0>; + gpmc,cs-on-ns = <0>; + gpmc,cs-rd-off-ns = <44>; + gpmc,cs-wr-off-ns = <44>; + gpmc,adv-on-ns = <6>; + gpmc,adv-rd-off-ns = <34>; + gpmc,adv-wr-off-ns = <44>; + gpmc,we-on-ns = <0>; + gpmc,we-off-ns = <40>; + gpmc,oe-on-ns = <0>; + gpmc,oe-off-ns = <54>; + gpmc,access-ns = <64>; + gpmc,rd-cycle-ns = <82>; + gpmc,wr-cycle-ns = <82>; + gpmc,wait-on-read = "true"; + gpmc,wait-on-write = "true"; + gpmc,bus-turnaround-ns = <0>; + gpmc,cycle2cycle-delay-ns = <0>; + gpmc,clk-activation-ns = <0>; + gpmc,wait-monitoring-ns = <0>; + gpmc,wr-access-ns = <40>; + gpmc,wr-data-mux-bus-ns = <0>; + partition@0 { + label = "X-Loader"; + reg = <0 0x80000>; + }; + partition@0x80000 { + label = "U-Boot"; + reg = <0x80000 0x1c0000>; + }; + partition@0x1c0000 { + label = "Environment"; + reg = <0x240000 0x40000>; + }; + partition@0x280000 { + label = "Kernel"; + reg = <0x280000 0x500000>; + }; + partition@0x780000 { + label = "Filesystem"; + reg = <0x780000 0xf880000>; + }; + }; +}; + +&mcspi1 { + pinctrl-names = "default"; + pinctrl-0 = <&mcspi1_pins>; + + m25p80@0 { + compatible = "w25x32"; + spi-max-frequency = <48000000>; + reg = <0>; + #address-cells = <1>; + #size-cells = <1>; + }; +}; + +&mmc1 { + vmmc-supply = <&vmmcsd_fixed>; +}; --- a/include/dt-bindings/pinctrl/omap.h +++ b/include/dt-bindings/pinctrl/omap.h @@ -61,6 +61,7 @@ #define OMAP3430_CORE2_IOPAD(pa, val) OMAP_IOPAD_OFFSET((pa), 0x25d8) (val) #define OMAP3630_CORE2_IOPAD(pa, val) OMAP_IOPAD_OFFSET((pa), 0x25a0) (val) #define OMAP3_WKUP_IOPAD(pa, val) OMAP_IOPAD_OFFSET((pa), 0x2a00) (val) +#define DM816X_IOPAD(pa, val) OMAP_IOPAD_OFFSET((pa), 0x0800) (val) #define AM33XX_IOPAD(pa, val) OMAP_IOPAD_OFFSET((pa), 0x0800) (val) #define AM4372_IOPAD(pa, val) OMAP_IOPAD_OFFSET((pa), 0x0800) (val) #define DRA7XX_CORE_IOPAD(pa, val) OMAP_IOPAD_OFFSET((pa), 0x3400) (val) -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
