+From 19a0ac654994661f63f7c9e099ed91a1210af161 Mon Sep 17 00:00:00 2001
+From: Stefan Wahren <wahrenst@gmx.net>
+Date: Sun, 6 Oct 2019 15:41:25 +0200
+Subject: [PATCH] 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
