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.

[1] - https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2711/rpi_DATA_2711_1p0_preliminary.pdf
[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

Martin Sperl (1):
  spi: bcm2835: enable shared interrupt support

Phil Elwell (2):
  ARM: bcm2835: DMA can only address 1GB

  dt-bindings: bcm2835-cprman: Add bcm2838 support
  clk: bcm2835: Add BCM2838_CLOCK_EMMC2 support
  dt-bindings: sdhci-iproc: Add brcm,bcm2838-emmc2
  mmc: sdhci-iproc: Add support for emmc2 of the BCM2838
