From: Christopher Spinrath <christopher.spinrath@xxxxxxxxxxxxxx> The cm-fx6 module has an on-board spi-flash chip for its firmware, an eeprom (containing e.g. the mac address of the on-board Ethernet), a sata port, a pcie controller, an USB hub, and an USB otg port. Enable support for them. In addition, enable syscon poweroff support. Signed-off-by: Christopher Spinrath <christopher.spinrath@xxxxxxxxxxxxxx> --- Changes since v1: - remove regulator pseudo-bus - remove partition layout from spi flash node - remove unneeded label of the spi flash node - convert downstream power-on-gpio property of pcie node to a proper regulator - sort usb* related nodes alphabetically - make use of GPIO_ACTIVE_{LOW,HIGH} defines - replace 0x80000000 iomuxc configs by proper defaults obtained from u-boot arch/arm/boot/dts/imx6q-cm-fx6.dts | 125 +++++++++++++++++++++++++++++++++++++ 1 file changed, 125 insertions(+) diff --git a/arch/arm/boot/dts/imx6q-cm-fx6.dts b/arch/arm/boot/dts/imx6q-cm-fx6.dts index 21c513f..c6f0e58 100644 --- a/arch/arm/boot/dts/imx6q-cm-fx6.dts +++ b/arch/arm/boot/dts/imx6q-cm-fx6.dts @@ -12,6 +12,7 @@ */ /dts-v1/; +#include <dt-bindings/gpio/gpio.h> #include "imx6q.dtsi" / { @@ -31,6 +32,49 @@ linux,default-trigger = "heartbeat"; }; }; + + reg_pcie_power_on_gpio: regulator-pcie-power-on-gpio { + compatible = "regulator-fixed"; + regulator-name = "regulator-pcie-power-on-gpio"; + regulator-min-microvolt = <3300000>; + regulator-max-microvolt = <3300000>; + gpio = <&gpio2 24 GPIO_ACTIVE_HIGH>; + enable-active-high; + }; + + reg_usb_h1_vbus: usb_h1_vbus { + compatible = "regulator-fixed"; + regulator-name = "usb_h1_vbus"; + regulator-min-microvolt = <5000000>; + regulator-max-microvolt = <5000000>; + gpio = <&gpio7 8 GPIO_ACTIVE_HIGH>; + enable-active-high; + }; + + reg_usb_otg_vbus: usb_otg_vbus { + compatible = "regulator-fixed"; + regulator-name = "usb_otg_vbus"; + regulator-min-microvolt = <5000000>; + regulator-max-microvolt = <5000000>; + gpio = <&gpio3 22 GPIO_ACTIVE_HIGH>; + enable-active-high; + }; +}; + +&ecspi1 { + fsl,spi-num-chipselects = <2>; + cs-gpios = <&gpio2 30 GPIO_ACTIVE_HIGH>, <&gpio3 19 GPIO_ACTIVE_HIGH>; + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_ecspi1>; + status = "okay"; + + m25p80@0 { + #address-cells = <1>; + #size-cells = <1>; + compatible = "st,m25p", "jedec,spi-nor"; + spi-max-frequency = <20000000>; + reg = <0>; + }; }; &fec { @@ -46,7 +90,30 @@ status = "okay"; }; +&i2c3 { + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_i2c3>; + status = "okay"; + clock-frequency = <100000>; + + eeprom@50 { + compatible = "at24,24c02"; + reg = <0x50>; + pagesize = <16>; + }; +}; + &iomuxc { + pinctrl_ecspi1: ecspi1grp { + fsl,pins = < + MX6QDL_PAD_EIM_D16__ECSPI1_SCLK 0x100b1 + MX6QDL_PAD_EIM_D17__ECSPI1_MISO 0x100b1 + MX6QDL_PAD_EIM_D18__ECSPI1_MOSI 0x100b1 + MX6QDL_PAD_EIM_EB2__GPIO2_IO30 0x100b1 + MX6QDL_PAD_EIM_D19__GPIO3_IO19 0x100b1 + >; + }; + pinctrl_enet: enetgrp { fsl,pins = < MX6QDL_PAD_RGMII_RXC__RGMII_RXC 0x1b0b0 @@ -90,12 +157,55 @@ >; }; + pinctrl_i2c3: i2c3grp { + fsl,pins = < + MX6QDL_PAD_GPIO_3__I2C3_SCL 0x4001b8b1 + MX6QDL_PAD_GPIO_6__I2C3_SDA 0x4001b8b1 + >; + }; + + pinctrl_pcie: pciegrp { + fsl,pins = < + MX6QDL_PAD_ENET_RXD1__GPIO1_IO26 0x1b0b1 + MX6QDL_PAD_EIM_CS1__GPIO2_IO24 0x1b0b1 + >; + }; + pinctrl_uart4: uart4grp { fsl,pins = < MX6QDL_PAD_KEY_COL0__UART4_TX_DATA 0x1b0b1 MX6QDL_PAD_KEY_ROW0__UART4_RX_DATA 0x1b0b1 >; }; + + pinctrl_usbh1: usbh1grp { + fsl,pins = < + MX6QDL_PAD_SD3_RST__GPIO7_IO08 0x1b0b1 + >; + }; + + pinctrl_usbotg: usbotggrp { + fsl,pins = < + MX6QDL_PAD_ENET_RX_ER__USB_OTG_ID 0x17059 + MX6QDL_PAD_EIM_D22__GPIO3_IO22 0x130b0 + >; + }; +}; + +&pcie { + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_pcie>; + reset-gpio = <&gpio1 26 GPIO_ACTIVE_HIGH>; + vdd-supply = <®_pcie_power_on_gpio>; + status = "okay"; +}; + +&sata { + status = "okay"; +}; + +&snvs_poweroff { + status = "okay"; }; &uart4 { @@ -103,3 +213,18 @@ pinctrl-0 = <&pinctrl_uart4>; status = "okay"; }; + +&usbh1 { + vbus-supply = <®_usb_h1_vbus>; + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_usbh1>; + status = "okay"; +}; + +&usbotg { + vbus-supply = <®_usb_otg_vbus>; + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_usbotg>; + dr_mode = "otg"; + status = "okay"; +}; -- 2.8.3 -- 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
