This file allows to factor the common parts between the various Keymile Kirkwood Designs.
kirkwood-km_common configures the peripherals that are currently common to all our Kirkwood designs: PCIe, pinctrl, bitbang I2C, NAND Flash controller. The kirkwood-km_kirkwood file is then changed to include this common file. Signed-off-by: Valentin Longchamp <[email protected]> --- Changes in v2: - introduce kirkwood-km_common.dtsi to allow factoring some nodes between boards arch/arm/boot/dts/kirkwood-km_common.dtsi | 48 ++++++++++++++++++++++++++++++ arch/arm/boot/dts/kirkwood-km_kirkwood.dts | 38 +---------------------- 2 files changed, 49 insertions(+), 37 deletions(-) create mode 100644 arch/arm/boot/dts/kirkwood-km_common.dtsi diff --git a/arch/arm/boot/dts/kirkwood-km_common.dtsi b/arch/arm/boot/dts/kirkwood-km_common.dtsi new file mode 100644 index 0000000..b241135 --- /dev/null +++ b/arch/arm/boot/dts/kirkwood-km_common.dtsi @@ -0,0 +1,48 @@ +/ { + chosen { + bootargs = "console=ttyS0,115200n8 earlyprintk"; + stdout-path = &uart0; + }; + + mbus { + pcie-controller { + status = "okay"; + + pcie@1,0 { + status = "okay"; + }; + }; + }; + + ocp@f1000000 { + pinctrl: pin-controller@10000 { + pinctrl-0 = < &pmx_i2c_gpio_sda &pmx_i2c_gpio_scl >; + pinctrl-names = "default"; + + pmx_i2c_gpio_sda: pmx-gpio-sda { + marvell,pins = "mpp8"; + marvell,function = "gpio"; + }; + pmx_i2c_gpio_scl: pmx-gpio-scl { + marvell,pins = "mpp9"; + marvell,function = "gpio"; + }; + }; + + serial@12000 { + status = "ok"; + }; + }; + + i2c@0 { + compatible = "i2c-gpio"; + gpios = < &gpio0 8 GPIO_ACTIVE_HIGH /* sda */ + &gpio0 9 GPIO_ACTIVE_HIGH>; /* scl */ + i2c-gpio,delay-us = <2>; /* ~100 kHz */ + }; +}; + +&nand { + status = "okay"; + chip-delay = <25>; +}; diff --git a/arch/arm/boot/dts/kirkwood-km_kirkwood.dts b/arch/arm/boot/dts/kirkwood-km_kirkwood.dts index 61139bf..235bf38 100644 --- a/arch/arm/boot/dts/kirkwood-km_kirkwood.dts +++ b/arch/arm/boot/dts/kirkwood-km_kirkwood.dts @@ -2,6 +2,7 @@ #include "kirkwood.dtsi" #include "kirkwood-98dx4122.dtsi" +#include "kirkwood-km_common.dtsi" / { model = "Keymile Kirkwood Reference Design"; @@ -11,43 +12,6 @@ device_type = "memory"; reg = <0x00000000 0x08000000>; }; - - chosen { - bootargs = "console=ttyS0,115200n8 earlyprintk"; - stdout-path = &uart0; - }; - - ocp@f1000000 { - pinctrl: pin-controller@10000 { - pinctrl-0 = < &pmx_i2c_gpio_sda &pmx_i2c_gpio_scl >; - pinctrl-names = "default"; - - pmx_i2c_gpio_sda: pmx-gpio-sda { - marvell,pins = "mpp8"; - marvell,function = "gpio"; - }; - pmx_i2c_gpio_scl: pmx-gpio-scl { - marvell,pins = "mpp9"; - marvell,function = "gpio"; - }; - }; - - serial@12000 { - status = "ok"; - }; - }; - - i2c@0 { - compatible = "i2c-gpio"; - gpios = < &gpio0 8 GPIO_ACTIVE_HIGH /* sda */ - &gpio0 9 GPIO_ACTIVE_HIGH>; /* scl */ - i2c-gpio,delay-us = <2>; /* ~100 kHz */ - }; -}; - -&nand { - status = "okay"; - chip-delay = <25>; }; &mdio { -- 1.8.0.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
