When people add multiple or common YAML files, they usually perform a full
dt_binding_check. Unfortunately, some YAML files cannot pass the self-check.
The errors or warning are listed below. It is necessary to eliminate them,
so that people's time and energy are not wasted every time when execute
comprehensive dt_binding_check.

This error is fixed by Patch 1:
/root/leizhen/linux-next/Documentation/devicetree/bindings/leds/leds-lp55xx.example.dt.yaml: led-controller@33: multi-led@2:color:0:0: 9 is greater than the maximum of 8
        From schema: /root/leizhen/linux-next/Documentation/devicetree/bindings/leds/leds-lp55xx.yaml

These errors are fixed by Patch 2:
/root/leizhen/linux-next/Documentation/devicetree/bindings/chrome/google,cros-ec-typec.example.dt.yaml: ec@0: 'typec' does not match any of the regexes: 'pinctrl-[0-9]+'

        From schema: /root/leizhen/linux-next/Documentation/devicetree/bindings/mfd/google,cros-ec.yaml

These errors are fixed by Patch 3 and 4:

The color value of multi-led is fixed to "const: 8 #LED_COLOR_ID_MULTI",
which is required by leds-class-multicolor.yaml.

There are so many properties have not been described in this yaml file,
and a lot of errors will be reported. Especially, some yaml files such as
google,cros-ec-typec.yaml, extcon-usbc-cros-ec.yaml can not pass the
self-check, because of the examples. So temporarily allow additional
properties to keep the comprehensive dt_binding_check result clean.

scripts/dtc/checks.c:
if (get_property(node, "spi-slave"))
	spi_addr_cells = 0;
if (node_addr_cells(node) != spi_addr_cells)
	FAIL(c, dti, node, "incorrect #address-cells for SPI bus");
if (node_size_cells(node) != 0)
	FAIL(c, dti, node, "incorrect #size-cells for SPI bus");

The above code in check_spi_bus_bridge() require that the number of address
cells must be 0. So we should explicitly declare "#address-cells = <0>".

Delete the old property "#address-cells" and then explicitly add it with
zero value. The value of "#size-cells" is already zero, so keep it no
change.

This is not correct.  ID_RGB is the correct variable here.

Correct fix is to update the leds-class-multicolor.yaml

My preference is to fix the binding to pass the checks and not just work 
around the issues. Working around the issues may mean the issues never 
get fixed.

Look at the search result below. It seems that the driver have not been merged into mainline.
But the property name is really used as cmd-gpio at mmp2-olpc-xo-1-75.dts:235, I don't think
the mmp2-olpc-xo-1-75.dts can make a mistake. Otherwise, the driver will not work properly.
Meanwhile, Both names cmd-gpios and cmd-gpio seem to be in use. But I prefer cmd-gpio, after
all, only one gpio is assigned now. The motorola,cmd-gpios add "s" because it contains 3 gpio.

I agree with your first sentence：don't just work around the issues. But these
errors are so annoying. Hope someone can add the description of the missing properties.
I'm not familiar with this module anyway.

And I don't fully agree with your last sentence. After all, the main properties are listed,
and the ones that are not listed should be minor ones.

Applied, thanks!

Note that I tried fixing this in dtc, but that was rejected. So this 
gets the schema in sync with dtc.

Yes, in drivers/platform/olpc/olpc-xo175-ec.c.

Your mistake is the gpiod api takes just 'cmd' as the GPIO core handles 
both forms.

The preference is it is always '-gpios' just like it's always 
'interrupts' or 'clocks'.

However, whether to change this is really up to the OLPC folks. Given 
the driver has always supported both forms, it should be okay to change 
the dts. Though there could be other users besides the kernel.

OK, thanks for your information. I have found that it defined by gpio_suffixes[].

If both "cmd-gpios" and "cmd-gpio" are supported, should we use enum to list both
of them in yaml? or use patternProperties?

I'm going to send v2 based on this idea.

Thanks for the patch.

I've sent out an equivalent one some time ago:
https://lore.kernel.org/lkml/20200925234805.228251-3-lkundrak@v3.sk/

In any case, either is fine with me.

Geert Uytterhoeven just replied me that the *-gpio form is deprecated. So your
patch is the correct one.

No, we pick one or the other. Given Lubomir is okay with a dts change,
we should use just 'cmd-gpios'.
