Subject: [PATCH 00/18] ARM: Add minimal Raspberry Pi 4 support
Date: Mon, 22 Jul 2019 07:54:31 +0200 [thread overview]
Message-ID: <1563774880-8061-1-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 BMC2711
Patch 6-10: Enable support for emmc2 on BCM2711
Patch 11-12: Enable pinctrl for BCM2711
Patch 13-17: Add Raspberry Pi 4 DTS support
Patch 18: Update MAINTAINERS
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].
Changes since RFC:
- change BCM2838 -> BCM2711 as discussed in RFC
- update MAINTAINERS accordingly
- drop "spi: bcm2835: enable shared interrupt support" from series
- squash all pinctrl-bcm2835 changes into one patch
- introduce SoC specific clock registration as suggested by Florian
- fix watchdog probing for Raspberry Pi 4
- convert brcm,bcm2835.txt to json-schema
- move VC4 node to bcm2835-common.dtsi
- fallback to legacy pull config for Raspberry Pi 4
- revert unintended change of mailbox in bcm283x.dtsi
- add reference for arm64
