Add support for the Libretech cottonwood board family.
These 2 boards are based on the same PCB, with an RPi B form factor.
The "Alta" board uses an a311d while the "Solitude" variant uses an s905d3.

I think those sound model properties should be coherent with the
other Libre Computer boards:
arch/arm64/boot/dts/amlogic/meson-gx-libretech-pc.dtsi: model = "LIBRETECH-PC";
arch/arm64/boot/dts/amlogic/meson-gxl-s805x-libretech-ac.dts: model = "LIBRETECH-AC";
arch/arm64/boot/dts/amlogic/meson-gxl-s905x-libretech-cc-v2.dts: model = "LIBRETECH-CC-V2";
arch/arm64/boot/dts/amlogic/meson-gxl-s905x-libretech-cc.dts: model = "LIBRETECH-CC";
It's ok to change the scheme since it's tried to keep the name under the 15 characters limit,
will the next board keep this naming ?

Are you sure you want this enabled ?
AFAIK if etnaviv is enabled, it will be used first as a render node by mesa and fail.

Not sure the PHY is the right place to put the USB HUB,
and it's probable the HUB is connected to both the USB2 and USB3 lines
so you should have both USB IDs in DT like it'd done for the Odroid-C4:
/ {
...
/* USB hub supports both USB 2.0 and USB 3.0 root hub */
usb-hub {
dr_mode = "host";
#address-cells = <1>;
#size-cells = <0>;
/* 2.0 hub on port 1 */
hub_2_0: hub@1 {
compatible = "usb2109,2817";
reg = <1>;
peer-hub = <&hub_3_0>;
reset-gpios = <&gpio GPIOH_4 GPIO_ACTIVE_LOW>;
vdd-supply = <&vcc_5v>;
};
/* 3.1 hub on port 4 */
hub_3_0: hub@2 {
compatible = "usb2109,817";
reg = <2>;
peer-hub = <&hub_2_0>;
reset-gpios = <&gpio GPIOH_4 GPIO_ACTIVE_LOW>;
vdd-supply = <&vcc_5v>;
};
};
...
};
if it only has a single USB ID, then it should go under the dwc3 node.

Apart that, it looks fine,

I think the formal model name is best, maybe with LC prefix.
eg. LC-AML-A311D-CC and LC-AML-S905D3-CC

USBHOST_A_DM and USBHOST_A_DP are connected to the USB 3 hub DM0 and DP0.
Not sure if this counts?

It should indeed be removed.

The first is valid. The second will be truncated to LC-AML-S905D3-C by the
alsa 15-character naming limit (mentioned below).
So name/rename them to:
LC-XXXXXXXXXXXX <= MAX SIZE (15 Chars)
LC-LEPOTATO
LC-LEPOTATO-V2
LC-LAFRITE
LC-TARTIFLETTE
LC-ALTA
LC-SOLITUDE
Personally I think the plain codenames (no "LC-“) work best as they are all
distinctive. Whenever I see lists of the official board names they look/read
the same at first glance and then I have to spot-the-difference to tell them
apart.
At the moment AFAIK these names are just cosmetic as there’s no Amlogic alsa
ucm confs using board model (only downstream confs based on driver name). So
IMHO rework the names now before the confs go upstream.

The USB bindings the USB devices nodes should be under the controller's node,
not the PHY, see:
Documentation/devicetree/bindings/usb/usb-hcd.yaml
...
patternProperties:
"^.*@[0-9a-f]{1,2}$":
description: The hard wired USB devices
type: object
$ref: /schemas/usb/usb-device.yaml
...
and the example.
Subnodes aren't allowed in the PHY node.

We changed them already because there was a clash from the 15 characters max width,
but now it's different.
So I think it's time to start a new clean scheme for the future LC boards, so:
LC-ALTA
LC-SOLITUDE
seems ok for me.
Using LC-AML-A311D-CC and LC-AML-S905D3-CC goes beyond the 15 chars limit.

Ditto, but you can simply use "led" since it's the only one.

The trigger does exist though. The other way is to extend the DT doc.
I don't really care one way or the other
I'll defer to Da on this one

That I do care. The schematics refer to the leds by name. There is no
number assigned, much less hex. Making one up makes no sense.
User should be able to quickly (and easily) link what they see in the
schematics with DT.
So I'd prefer to submit a change for the regex rather than changing this

It should (and initally was)
It was coming funny '(null)-standby' in sysfs and I did really checked
why
I can change it back, no problem

We can and should use heartbeat to both be consistent and also show

I don't get why the LEDs should be hex either. It's contradictory to
https://www.kernel.org/doc/html/latest/leds/leds-class.html
I did a simple grep and didn't find any references to
LED_COLOR_ID_ORANGE. We can debug this later.

Ok, that is what schema says.
HW wise there is possible problem though.
The phy node has the power supply to the bus.
In that case it is a controllable one.
If fixed USB devices go under the controller instead of the PHY, isn't
it possible that the kernel may attempt to probe them before the bus is
powered ? For this particular board, it would make the reset we are
trying to apply useless.

The usb core has a special handling for those usb hubs doing the power
up at the right time during the USB setup, including the PHY powering up.
So the power sequence should be fine.
This has been done on Odroid-C2 and Odroid-N2 already.

Tried it. Unfortunately something is off with the hub under the dwc3 node
I often get this error (like once in 3 boots):

While it works reliably when the onboard-usb-hub is under the phy node.
I added the 5v supply as vdd under the hub for good measure.

The .reset_us you used from genesys_gl852g is probably too low, you may need to use a bigger one then.
