Signed-off-by: Matthias Klein --- Changes in v2: - move the common parts between the B and B+ model into the new bcm2835-rpi.dtsi file - add the I2S signals to the B+ file which fix the problem that USB is not working with the current bcm2835-rpi-b.dts file on the B+. --- arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/bcm2835-rpi-b-plus.dts | 30 +++++++++++++++++++ arch/arm/boot/dts/bcm2835-rpi-b.dts | 46 ++-------------------------- arch/arm/boot/dts/bcm2835-rpi.dtsi | 51 ++++++++++++++++++++++++++++++++ 4 files changed, 85 insertions(+), 43 deletions(-) create mode 100644 arch/arm/boot/dts/bcm2835-rpi-b-plus.dts create mode 100644 arch/arm/boot/dts/bcm2835-rpi.dtsi diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index aaae0d6..29e18ee 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -54,6 +54,7 @@ dtb-$(CONFIG_ARCH_AT91) += at91-sama5d4ek.dtb dtb-$(CONFIG_ARCH_ATLAS6) += atlas6-evb.dtb dtb-$(CONFIG_ARCH_AXXIA) += axm5516-amarillo.dtb dtb-$(CONFIG_ARCH_BCM2835) += bcm2835-rpi-b.dtb +dtb-$(CONFIG_ARCH_BCM2835) += bcm2835-rpi-b-plus.dtb dtb-$(CONFIG_ARCH_BCM_5301X) += bcm4708-netgear-r6250.dtb dtb-$(CONFIG_ARCH_BCM_63XX) += bcm963138dvt.dtb dtb-$(CONFIG_ARCH_BCM_MOBILE) += bcm28155-ap.dtb \ diff --git a/arch/arm/boot/dts/bcm2835-rpi-b-plus.dts b/arch/arm/boot/dts/bcm2835-rpi-b-plus.dts new file mode 100644 index 0000000..e479515 --- /dev/null +++ b/arch/arm/boot/dts/bcm2835-rpi-b-plus.dts @@ -0,0 +1,30 @@ +/dts-v1/; +/include/ "bcm2835-rpi.dtsi" + +/ { + compatible = "raspberrypi,model-b-plus", "brcm,bcm2835"; + model = "Raspberry Pi Model B+"; + + leds { + act { + gpios = <&gpio 47 0>; + }; + + pwr { + label = "PWR"; + gpios = <&gpio 35 0>; + default-state = "keep"; + linux,default-trigger = "default-on"; + }; + }; +}; + +&gpio { + pinctrl-0 = <&gpioout &alt0 &i2s_alt0 &alt3>; + + /* I2S interface */ + i2s_alt0: i2s_alt0 { + brcm,pins = <18 19 20 21>; + brcm,function = <4>; /* alt0 */ + }; +}; diff --git a/arch/arm/boot/dts/bcm2835-rpi-b.dts b/arch/arm/boot/dts/bcm2835-rpi-b.dts index 58a0d60..bafa46f 100644 --- a/arch/arm/boot/dts/bcm2835-rpi-b.dts +++ b/arch/arm/boot/dts/bcm2835-rpi-b.dts @@ -1,63 +1,23 @@ /dts-v1/; -/include/ "bcm2835.dtsi" +/include/ "bcm2835-rpi.dtsi" / { compatible = "raspberrypi,model-b", "brcm,bcm2835"; model = "Raspberry Pi Model B"; - memory { - reg = <0 0x10000000>; - }; - leds { - compatible = "gpio-leds"; - act { - label = "ACT"; gpios = <&gpio 16 1>; - default-state = "keep"; - linux,default-trigger = "heartbeat"; }; }; }; &gpio { - pinctrl-names = "default"; - pinctrl-0 = <&gpioout &alt0 &alt2 &alt3>; - - gpioout: gpioout { - brcm,pins = <6>; - brcm,function = <1>; /* GPIO out */ - }; - - alt0: alt0 { - brcm,pins = <0 1 2 3 4 5 7 8 9 10 11 14 15 40 45>; - brcm,function = <4>; /* alt0 */ - }; - - alt3: alt3 { - brcm,pins = <48 49 50 51 52 53>; - brcm,function = <7>; /* alt3 */ - }; + pinctrl-0 = <&gpioout &alt0 &i2s_alt2 &alt3>; /* I2S interface */ - alt2: alt2 { + i2s_alt2: i2s_alt2 { brcm,pins = <28 29 30 31>; brcm,function = <6>; /* alt2 */ }; }; - -&i2c0 { - status = "okay"; - clock-frequency = <100000>; -}; - -&i2c1 { - status = "okay"; - clock-frequency = <100000>; -}; - -&sdhci { - status = "okay"; - bus-width = <4>; -}; diff --git a/arch/arm/boot/dts/bcm2835-rpi.dtsi b/arch/arm/boot/dts/bcm2835-rpi.dtsi new file mode 100644 index 0000000..c706448 --- /dev/null +++ b/arch/arm/boot/dts/bcm2835-rpi.dtsi @@ -0,0 +1,51 @@ +/include/ "bcm2835.dtsi" + +/ { + memory { + reg = <0 0x10000000>; + }; + + leds { + compatible = "gpio-leds"; + + act { + label = "ACT"; + default-state = "keep"; + linux,default-trigger = "heartbeat"; + }; + }; +}; + +&gpio { + pinctrl-names = "default"; + + gpioout: gpioout { + brcm,pins = <6>; + brcm,function = <1>; /* GPIO out */ + }; + + alt0: alt0 { + brcm,pins = <0 1 2 3 4 5 7 8 9 10 11 14 15 40 45>; + brcm,function = <4>; /* alt0 */ + }; + + alt3: alt3 { + brcm,pins = <48 49 50 51 52 53>; + brcm,function = <7>; /* alt3 */ + }; +}; + +&i2c0 { + status = "okay"; + clock-frequency = <100000>; +}; + +&i2c1 { + status = "okay"; + clock-frequency = <100000>; +}; + +&sdhci { + status = "okay"; + bus-width = <4>; +}; -- 2.1.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
