-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
