Subject: [PATCH v3 3/4] arm64: dts: marvell: Add Armada 98DX2530 SoC and RD-AC5X board
The 98DX2530 SoC is the Control and Management CPU integrated into
the Marvell 98DX25xx and 98DX35xx series of switch chip (internally
referred to as AlleyCat5 and AlleyCat5X).
These files have been taken from the Marvell SDK and lightly cleaned

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 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.
