[PATCH v2 0/6] Add two board-families from Theobroma-Systems

[PATCH v2 0/6] Add two board-families from Theobroma-Systems

[Heiko Stuebner]

Both the Cobra and PP1516 boards are based around the PX30 SoC and can be
found with a variety of display options.

As new boards should not use the deprecated snps,reset-* properties
in the gmac node, I also added a core mdio-node for the gmac and
converted the Theobroma Ringneck board over.

Testing with the new node both before and after converting Ringneck
showed the board finding its network both when booting locally and
from the tftp/nfs.

changes in v2:
- add received Acks/Reviews
- drop "rockchip" prefix from system-power-controller (Diederik)
- split out prototype-pins to prototype variant
- address Quentin's review comments
  - ethernet0 alias for Cobra
  - a number more pinctrl entries for gpios
  - drop unused slp pinctrl entries
  - additional comments
  - use gpio-constants for pmic int
  - ordering (nodes + properties)
  - clarify vccio_sd more
  - interrupt line for pp1516 accelerometer

[PATCH v2 1/6] arm64: dts: rockchip: add basic mdio node to px30

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner@cherry.de>

Using snps,reset-* properties for handling the phy-reset is deprecated
and instead a real phy node should be defined that then contains the
reset-gpios handling.

To facilitate this, add the core mdio node under the px30's gmac, similar
to how the other Rockchip socs already do this.

[PATCH v2 5/6] dt-bindings: arm: rockchip: add PX30-PP1516 boards from Theobroma Systems

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner@cherry.de>

PP1516 are Touchscreen devices built around the PX30 SoC and companion
devices to PX30-Cobra, again with multiple display options.

The devices feature an EMMC, OTG port and a 720x1280 display with a
touchscreen and camera

Please order the properties alphabetically, system-power-controller is 
not where it should be.

I would actually have a pull down here to hold the display in reset 
until the driver is probed and goes through the reset procedure?

With the two above done:

The accelerometer is not in the camera module like some of our other 
products, but on the PCBA directly, so I would put it in a different 
section in the pinctrl node.

Can you have it this way too:

rockchip,pins =
         <2 RK_PB4 RK_FUNC_GPIO &pcfg_pull_none>;

so it is consistent with the other ones?

Same remark as for Cobra, I assume we want a pull down here, to keep in 
reset until the driver probe drives the pin to orchestrate the reset?
