The RPi 4 is available in 3 different variants (1, 2 and 4 GB RAM), so leave the memory size to zero and let the bootloader take care of it. The DWC2 is still usable as peripheral via the USB-C port. Other differences to the Raspberry Pi 3: - additional GIC 400 Interrupt controller - new thermal IP and HWRNG - additional MMC interface (emmc2) - additional UART, I2C, SPI and PWM interfaces - clock stretching bug in I2C IP has been fixed Signed-off-by: Stefan Wahren Acked-by: Eric Anholt --- arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/bcm2711-rpi-4-b.dts | 121 ++++ arch/arm/boot/dts/bcm2711.dtsi | 662 ++++++++++++++++++++++ arch/arm/boot/dts/bcm283x-rpi-usb-peripheral.dtsi | 7 + arch/arm/boot/dts/bcm283x.dtsi | 4 +- 5 files changed, 793 insertions(+), 2 deletions(-) create mode 100644 arch/arm/boot/dts/bcm2711-rpi-4-b.dts create mode 100644 arch/arm/boot/dts/bcm2711.dtsi create mode 100644 arch/arm/boot/dts/bcm283x-rpi-usb-peripheral.dtsi -- 2.7.4 diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 9159fa2..031ca32 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -83,6 +83,7 @@ dtb-$(CONFIG_ARCH_BCM2835) += \ bcm2837-rpi-3-b.dtb \ bcm2837-rpi-3-b-plus.dtb \ bcm2837-rpi-cm3-io3.dtb \ + bcm2711-rpi-4-b.dtb \ bcm2835-rpi-zero.dtb \ bcm2835-rpi-zero-w.dtb dtb-$(CONFIG_ARCH_BCM_5301X) += \ diff --git a/arch/arm/boot/dts/bcm2711-rpi-4-b.dts b/arch/arm/boot/dts/bcm2711-rpi-4-b.dts new file mode 100644 index 0000000..3825273 --- /dev/null +++ b/arch/arm/boot/dts/bcm2711-rpi-4-b.dts @@ -0,0 +1,121 @@ +// SPDX-License-Identifier: GPL-2.0 +/dts-v1/;
