These files have been taken from the Marvell SDK and lightly cleaned up with the License and copyright retained. Signed-off-by: Chris Packham Reviewed-by: Andrew Lunn --- Notes: The Marvell SDK has a number of new compatible strings. I've brought through some of the drivers or where possible used an in-tree alternative (e.g. there is SDK code for a ac5-gpio but two instances of the existing marvell,orion-gpio seems to cover what is needed if you use an appropriate binding). I expect that there will a new series of patches when I get some different hardware (or additions to this series depending on if/when it lands). Changes in v5: - add #{address,size}-cells property to i2c nodes - make i2c nodes disabled in the SoC and enable them in the board - add interrupt controller attributes to gpio nodes - Move fixed-clock nodes up a level and remove unnecessary @0 Changes in v4: - use 'phy-handle' instead of 'phy' - move status="okay" on usb nodes to board dts - Add review from Andrew Changes in v3: - Move memory node to board - Use single digit reg value for phy address - Remove MMC node (driver needs work) - Remove syscon & simple-mfd for pinctrl Changes in v2: - Make pinctrl a child node of a syscon node - Use marvell,armada-8k-gpio instead of orion-gpio - Remove nand peripheral. The Marvell SDK does have some changes for the ac5-nand-controller but I currently lack hardware with NAND fitted so I can't test it right now. I've therefore chosen to omit the node and not attempted to bring in the driver or binding. - Remove pcie peripheral. Again there are changes in the SDK and I have no way of testing them. - Remove prestera node. - Remove "marvell,ac5-ehci" compatible from USB node as "marvell,orion-ehci" is sufficient - Remove watchdog node. There is a buggy driver for the ac5 watchdog in the SDK but it needs some work so I've dropped the node for now. arch/arm64/boot/dts/marvell/Makefile | 1 + .../boot/dts/marvell/armada-98dx2530.dtsi | 310 ++++++++++++++++++ arch/arm64/boot/dts/marvell/rd-ac5x.dts | 90 +++++ 3 files changed, 401 insertions(+) create mode 100644 arch/arm64/boot/dts/marvell/armada-98dx2530.dtsi create mode 100644 arch/arm64/boot/dts/marvell/rd-ac5x.dts diff --git a/arch/arm64/boot/dts/marvell/Makefile b/arch/arm64/boot/dts/marvell/Makefile index 1c794cdcb8e6..3905dee558b4 100644 --- a/arch/arm64/boot/dts/marvell/Makefile +++ b/arch/arm64/boot/dts/marvell/Makefile @@ -24,3 +24,4 @@ dtb-$(CONFIG_ARCH_MVEBU) += cn9132-db.dtb dtb-$(CONFIG_ARCH_MVEBU) += cn9132-db-B.dtb dtb-$(CONFIG_ARCH_MVEBU) += cn9130-crb-A.dtb dtb-$(CONFIG_ARCH_MVEBU) += cn9130-crb-B.dtb +dtb-$(CONFIG_ARCH_MVEBU) += rd-ac5x.dtb diff --git a/arch/arm64/boot/dts/marvell/armada-98dx2530.dtsi b/arch/arm64/boot/dts/marvell/armada-98dx2530.dtsi new file mode 100644 index 000000000000..ec4cfb17a260 --- /dev/null +++ b/arch/arm64/boot/dts/marvell/armada-98dx2530.dtsi @@ -0,0 +1,310 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Device Tree For AC5. + * + * Copyright (C) 2021 Marvell + * + */ + +/dts-v1/;
