[v1,35/43] ARM: dts: add device tree for ep93xx Soc
Commit Message
This adds a divice for Cirrus ep93xx SoC amd ts7250 board that has been
my testing target for ep93xx device support.
Also inluded device tree for Liebherr BK3.1 board through it's not a
complete support.

Notes:
v0 -> v1:
- add empty chosen node
- s/dallas,rtc-m48t86/st,m48t86/
- changed phy_id to phy-handle
- dropped gpio chip-label's
- s/eth@80010000/ethernet@80010000
- s/use_dma/ep9301,use-dma
- added i2s to bk3

Thank you for your patch. There is something to discuss/improve.

Split adding DTSI from adding boards.

Use proper defines for flags.

Up to you, but I seriously recommend keeping all labels ordered by name.
Avoids conflicts.

??? I don't understand. Why would you do this?

Broken wrapping. Align these with previous ".

Just "reboot" (and fix bindings)... but why would you need it in the
first place? I think something is seriously missing in your bindings.

I would expect somewhere two groups since you explicitly allow it.

compatible first, reg is second. ranges if present - third. Fix it

This should scream with dtbs_check. serial.
It does not look like you tested the DTS against bindings. Please run
`make dtbs_check` (see

Your SoC comes with mdio? If so, why is this empty?

defines... but why is it here in the first place? Rarely CS gpios are
part of the SoC. I have several of such questions further as well, so
this looks like you are mixing SoC and boards in one file.

Wait, what? Why this is disabled? If this is part of the SoC, although
hardly looks like, then it should be complete. What is missing? How one
could design SoC with incomplete GPIO I2C controller?

I really doubt this is property of the SoC. Please double check as it
really looks wrong.

You are right - it's SoC specific, but currently we only have boards
with ep9302 with according device trees:
- ts7250
- bk3
- edb9302
We were hoping someone with other SoC's will join - like Hartley
Sweeten with Vision Engraving Systems EP9307 SoM, but no one showed up.
I've changed added compatible "cirrus,ep9301-pinctrl" in ep93xx.dtsi as
default and removed from all other board .dts.

It has a builtin MDIO and only reason for this is to provide phy-id via
device tree in a correct way:
```
ð0 {
phy-handle = <&phy0>;
};
&mdio0 {
phy0: ethernet-phy@1 {
reg = <1>;
device_type = "ethernet-phy";
};
};
```
There is no other purpose for this node.
Thank you Krzysztof!
All other issues fixed.
