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 [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 Phil Elwell (1): ARM: bcm2835: DMA can only address 1GB Stefan Wahren (17): ARM: bcm283x: Reduce register ranges for UART, SPI and I2C ARM: dts: bcm283x: Move BCM2835/6/7 specific to bcm2835-common.dtsi ARM: dts: bcm283x: Define MMC interfaces at board level ARM: dts: bcm283x: Define memory at board level dt-bindings: bcm2835-cprman: Add bcm2711 support clk: bcm2835: Introduce SoC specific clock registration clk: bcm2835: Add BCM2711_CLOCK_EMMC2 support dt-bindings: sdhci-iproc: Add brcm,bcm2711-emmc2 mmc: sdhci-iproc: Add support for emmc2 of the BCM2711 dt-bindings: pinctrl: bcm2835: Add brcm,bcm2711 compatible pinctrl: bcm2835: Add support for BCM2711 pull-up functionality dt-bindings: arm: Convert BCM2835 board/soc bindings to json-schema dt-bindings: arm: bcm2835: Add Raspberry Pi 4 to DT schema ARM: bcm2835: Add bcm2711 compatible string ARM: dts: Add minimal Raspberry Pi 4 support arm64: dts: broadcom: Add reference to RPi 4 B MAINTAINERS: Add BCM2711 to BCM2835 ARCH .../devicetree/bindings/arm/bcm/bcm2835.yaml | 51 ++ .../devicetree/bindings/arm/bcm/brcm,bcm2835.txt | 67 --- .../bindings/clock/brcm,bcm2835-cprman.txt | 4 +- .../devicetree/bindings/mmc/brcm,sdhci-iproc.txt | 4 +- .../bindings/pinctrl/brcm,bcm2835-gpio.txt | 1 + MAINTAINERS | 3 +- arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/bcm2711-rpi-4-b.dts | 120 ++++ arch/arm/boot/dts/bcm2711.dtsi | 667 +++++++++++++++++++++ arch/arm/boot/dts/bcm2835-common.dtsi | 177 ++++++ arch/arm/boot/dts/bcm2835-rpi-a-plus.dts | 12 + arch/arm/boot/dts/bcm2835-rpi-a.dts | 12 + arch/arm/boot/dts/bcm2835-rpi-b-plus.dts | 12 + arch/arm/boot/dts/bcm2835-rpi-b-rev2.dts | 12 + arch/arm/boot/dts/bcm2835-rpi-b.dts | 12 + arch/arm/boot/dts/bcm2835-rpi-cm1-io1.dts | 7 + arch/arm/boot/dts/bcm2835-rpi-cm1.dtsi | 5 + arch/arm/boot/dts/bcm2835-rpi-zero-w.dts | 12 + arch/arm/boot/dts/bcm2835-rpi-zero.dts | 12 + arch/arm/boot/dts/bcm2835-rpi.dtsi | 18 - arch/arm/boot/dts/bcm2835.dtsi | 1 + arch/arm/boot/dts/bcm2836-rpi-2-b.dts | 8 + arch/arm/boot/dts/bcm2836.dtsi | 1 + arch/arm/boot/dts/bcm2837-rpi-3-a-plus.dts | 1 + arch/arm/boot/dts/bcm2837-rpi-3-b-plus.dts | 1 + arch/arm/boot/dts/bcm2837-rpi-3-b.dts | 1 + arch/arm/boot/dts/bcm2837-rpi-cm3-io3.dts | 7 + arch/arm/boot/dts/bcm2837-rpi-cm3.dtsi | 1 + arch/arm/boot/dts/bcm2837.dtsi | 1 + arch/arm/boot/dts/bcm283x.dtsi | 160 +---- arch/arm/mach-bcm/board_bcm2835.c | 2 + arch/arm64/boot/dts/broadcom/Makefile | 3 +- arch/arm64/boot/dts/broadcom/bcm2711-rpi-4-b.dts | 2 + drivers/clk/bcm/clk-bcm2835.c | 117 +++- drivers/mmc/host/sdhci-iproc.c | 9 + drivers/pinctrl/bcm/pinctrl-bcm2835.c | 105 +++- include/dt-bindings/clock/bcm2835.h | 2 + 37 files changed, 1365 insertions(+), 266 deletions(-) create mode 100644 Documentation/devicetree/bindings/arm/bcm/bcm2835.yaml delete mode 100644 Documentation/devicetree/bindings/arm/bcm/brcm,bcm2835.txt create mode 100644 arch/arm/boot/dts/bcm2711-rpi-4-b.dts create mode 100644 arch/arm/boot/dts/bcm2711.dtsi create mode 100644 arch/arm/boot/dts/bcm2835-common.dtsi create mode 100644 arch/arm64/boot/dts/broadcom/bcm2711-rpi-4-b.dts -- 2.7.4
