Subject: [PATCH RFC 00/18] ARM: Add minimal Raspberry Pi 4 support
Date: Wed, 17 Jul 2019 21:50:08 +0200
Message-ID: <1563393026-17118-1-git-send-email-wahrenst@gmx.net> (raw)
This series adds minimal support for the new Raspberry Pi 4, so we are able
to login via debug UART.
Patch 1-5: Prepare platform and DTS for the new SoC BMC2838
Patch 6-9: Enable support for emmc2 on BCM2838
Patch 10-14: Enable pinctrl for BCM2838
Patch 15: Enable SPI support for BCM2838
Patch 16-18: Add Raspberry Pi 4 DTS support
Unfortunately the Raspberry Pi Foundation didn't released a
peripheral documentation for the new SoC yet. So we only have a preliminary
datasheet [1] and reduced schematics [2].
This series is marked as RFC because some parts (e.g. pinctrl) are still
work in progress.

[2] - https://www.raspberrypi.org/documentation/hardware/raspberrypi/schematics/rpi_SCH_4b_4p0_reduced.pdf
Discussible things:
- SoC compatible BCM2711 (as on the SoC label) vs BCM2838 (existing naming scheme)
- ARCH membership ARCH_BCM2835 vs ARCH_BCMSTB
...
Al Cooper (1):
pinctrl: bcm2835: bcm7211: Add support for 7211 pull-up functionality
