[PATCH v2 0/3] board: rockchip: add OneThing Edge Cube series

[Jun Yan]

This series adds support for the OneThing Edge Cube series, which were
initially marketed by OneThing Tech as PCDN (P2P Content Delivery Network) 
devices. The Edge Cube series is based on Rockchip RK3566 SoC and is designed
for PCDN applications.

The V2 patches adds a new device, the OneThing OEC. Together with the V1 patch 
OneThing OEC-turbo, these two devices share identical hardware specifications
except for the RAM capacity, enabling convenient support implementation.

The V1 patch was submitted quite some time ago and is now in an archived state[1].
it has not been processed due to scheduling conflicts – apologies for this.

Changes in v2:
- Fix typo in vendor-prefixes.
- Simplify company and device names.
- Add the new device OEC as part of the OneThing Edge Cube series for support.
- Set display-subsystem node to "disabled" instead of using "delete-node".
- Using generic node names for leds.
- Follow DTS codeing style in vcc5v0_usb_host_en pinctrl node.
- Modify the phy_mode of GMAC from rgmii to rgmii-id.
- Adjust device tree node ordering to follow code style.

[PATCH 2/3] dt-bindings: arm: rockchip: Add OneThing Edge Cube series

[Jun Yan]

Add devicetree binding for the OneThing OEC and OEC-turbo

The OneThing Edge Cube (OEC) series features the RK3566 SoC, 8GB
eMMC storage, and supports one SATA interface, one Gigabit Ethernet
port, and one USB 3.0 port.
Among the lineup, the standard OEC model comes with 2GB of RAM, while
the OEC-turbo features 4GB of RAM; The rest of the specifications are
identical.

The OneThing Edge Cube series (shipping with the vendor firmware) is
originally designed as a PCDN (P2P Content Delivery Network) device.

This doesn't match your dts, so clearly you have not tested this
sufficiently. oec and oec-turbo should be in an enum.

Sorry for that. Following Dragan Simic's suggestion, I will merge 
these two board items into one in the V3 patch set.

Other than the difference in RAM capacity, the OEC and OEC-turbo are
identical in all other specifications.

  Specification:
    - Rockchip RK3566
    - LPDDR4X 2GB (OEC) / 4GB (OEC-turbo)
    - eMMC 8GB
    - Gigabit Ethernet port x 1
    - USB 3.0 port x 1
    - USB-C 2.0 port x 1
    - 12V DC Power supply
    - SATA 3.0 connector x 1

The only difference between the two OneThing OEC board variants is, as
far as I can tell, the amount of LPDDR4X DRAM they have, so I don't think
it's justified to have two separate board dts files that descend from the
common dtsi ancestor.

Having different amounts of DRAM on the same board design is present on
virtually all boards from other manufacturers, and some kind of special
DT treatment is needed only in some special cases, such as when different
types of DRAM are used for different capacities.

The different naming of the two board variants could be solved by having
something like this is the single board dts file:

  model = "OneThing OEC/OEC-turbo";

Having two separate board dts files only makes it harder down the road,
such as having to build and provide two separate U-Boot builds, with no
real benefits.  Every user can run free(1) to check the amount of available
DRAM on their board, which also tells them the board variant.

I agree with your suggestion and will implement it in the V3 patch set. 
Thanks for your valuable feedback!
