From 7dbe8c62ceeb8898d2c12d95c0714306d1cfba25 Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Sun, 6 Oct 2019 15:41:25 +0200 Subject: ARM: dts: Add minimal Raspberry Pi 4 support This adds minimal support for the new Raspberry Pi 4 without the fancy stuff like GENET, PCIe, xHCI, 40 bit DMA and V3D. 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 Acked-by: Florian Fanelli --- arch/arm/boot/dts/bcm283x.dtsi | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'arch/arm/boot/dts/bcm283x.dtsi') diff --git a/arch/arm/boot/dts/bcm283x.dtsi b/arch/arm/boot/dts/bcm283x.dtsi index addf3bea15c9..3caaa57eb6c8 100644 --- a/arch/arm/boot/dts/bcm283x.dtsi +++ b/arch/arm/boot/dts/bcm283x.dtsi @@ -53,7 +53,7 @@ #address-cells = <1>; #size-cells = <1>; - timer@7e003000 { + system_timer: timer@7e003000 { compatible = "brcm,bcm2835-system-timer"; reg = <0x7e003000 0x1000>; interrupts = <1 0>, <1 1>, <1 2>, <1 3>; @@ -64,7 +64,7 @@ clock-frequency = <1000000>; }; - txp@7e004000 { + txp: txp@7e004000 { compatible = "brcm,bcm2835-txp"; reg = <0x7e004000 0x20>; interrupts = <1 11>; -- cgit
