With the -introduction of an I2C mux to share I2C0 between the camera/display -connectors and the IDC headers, the difference between the two versions -becomes too great to comfortably manage with tweaking, hence this split. - -Upstream DTS files already have bcm2835-rpi-b.dts and -bcm2835-rpi-b-rev2.dts, but for backwards compatibility the new file is -being added as bcm2708-rpi-b-rev1.dts, rather than renaming the old -shared version to bcm2708-rpi-b-rev2.dts. - -Signed-off-by: Phil Elwell <phil@raspberrypi.com> ---- - arch/arm/boot/dts/Makefile | 1 + - arch/arm/boot/dts/bcm2708-rpi-b-rev1.dts | 127 +++++++++++++++++++++++ - arch/arm/boot/dts/bcm270x-rpi.dtsi | 4 + - 3 files changed, 132 insertions(+) - create mode 100644 arch/arm/boot/dts/bcm2708-rpi-b-rev1.dts - ---- a/arch/arm/boot/dts/Makefile -+++ b/arch/arm/boot/dts/Makefile -@@ -2,6 +2,7 @@ - - dtb-$(CONFIG_ARCH_BCM2835) += \ - bcm2708-rpi-b.dtb \ -+ bcm2708-rpi-b-rev1.dtb \ - bcm2708-rpi-b-plus.dtb \ - bcm2708-rpi-cm.dtb \ - bcm2708-rpi-zero.dtb \ ---- /dev/null -+++ b/arch/arm/boot/dts/bcm2708-rpi-b-rev1.dts -@@ -0,0 +1,127 @@ -+/dts-v1/; -+ -+#include "bcm2708.dtsi" -+#include "bcm2708-rpi.dtsi" -+#include "bcm283x-rpi-smsc9512.dtsi" -+#include "bcm283x-rpi-csi1-2lane.dtsi" -+ -+/ { -+ compatible = "raspberrypi,model-b", "brcm,bcm2835"; -+ model = "Raspberry Pi Model B"; -+}; -+ -+&gpio { -+ spi0_pins: spi0_pins { -+ brcm,pins = <9 10 11>; -+ brcm,function = <4>; /* alt0 */ -+ }; -+ -+ spi0_cs_pins: spi0_cs_pins { -+ brcm,pins = <8 7>; -+ brcm,function = <1>; /* output */ -+ }; -+ -+ i2c0_pins: i2c0 { -+ brcm,pins = <0 1>; -+ brcm,function = <4>; -+ }; -+ -+ i2c1_pins: i2c1 { -+ brcm,pins = <2 3>; -+ brcm,function = <4>; -+ }; -+ -+ i2s_pins: i2s { -+ brcm,pins = <28 29 30 31>; -+ brcm,function = <6>; /* alt2 */ -+ }; -+ -+ audio_pins: audio_pins { -+ brcm,pins = <40 45>; -+ brcm,function = <4>; -+ }; -+}; -+ -+&uart0 { -+ status = "okay"; -+}; -+ -+&spi0 { -+ pinctrl-names = "default"; -+ pinctrl-0 = <&spi0_pins &spi0_cs_pins>; -+ cs-gpios = <&gpio 8 1>, <&gpio 7 1>; -+ -+ spidev0: spidev@0{ -+ compatible = "spidev"; -+ reg = <0>; /* CE0 */ -+ #address-cells = <1>; -+ #size-cells = <0>; -+ spi-max-frequency = <125000000>; -+ }; -+ -+ spidev1: spidev@1{ -+ compatible = "spidev"; -+ reg = <1>; /* CE1 */ -+ #address-cells = <1>; -+ #size-cells = <0>; -+ spi-max-frequency = <125000000>; -+ }; -+}; -+ -+/delete-node/ &i2c0mux; -+ -+i2c0: &i2c0if { -+ pinctrl-names = "default"; -+ pinctrl-0 = <&i2c0_pins>; -+ clock-frequency = <100000>; -+}; -+ -+i2c_csi_dsi: &i2c1 { -+ pinctrl-names = "default"; -+ pinctrl-0 = <&i2c1_pins>; -+ clock-frequency = <100000>; -+}; -+ -+/ { -+ aliases { -+ i2c0 = &i2c0; -+ }; -+ -+ __overrides__ { -+ i2c0 = <&i2c0>, "status"; -+ }; -+}; -+ -+&i2c2 { -+ clock-frequency = <100000>; -+}; -+ -+&i2s { -+ pinctrl-names = "default"; -+ pinctrl-0 = <&i2s_pins>; -+}; -+ -+&leds { -+ act_led: act { -+ label = "led0"; -+ linux,default-trigger = "mmc0"; -+ gpios = <&gpio 16 1>; -+ }; -+}; -+ -+&hdmi { -+ hpd-gpios = <&gpio 46 GPIO_ACTIVE_HIGH>; -+}; -+ -+&audio { -+ pinctrl-names = "default"; -+ pinctrl-0 = <&audio_pins>; -+}; -+ -+/ { -+ __overrides__ { -+ act_led_gpio = <&act_led>,"gpios:4"; -+ act_led_activelow = <&act_led>,"gpios:8"; -+ act_led_trigger = <&act_led>,"linux,default-trigger"; -+ }; -+}; ---- a/arch/arm/boot/dts/bcm270x-rpi.dtsi -+++ b/arch/arm/boot/dts/bcm270x-rpi.dtsi -@@ -110,6 +110,10 @@ - status = "disabled"; - }; - -+&i2c0mux { -+ status = "disabled"; -+}; -+ - &i2c1 { - status = "disabled"; - }; |
