this has to be system-power-controller;

And you have it correctly here:
https://gitlab.postmarketos.org/postmarketOS/pmaports/-/blob/master/device/community/linux-postmarketos-omap/0002-arm-dts-Add-common-dtsi-for-espresso.patch?ref_type=heads#L532

so, please double-check if you are trying to mainline the right branch.
No need to respin just for this line. There is still a lot other stuff
to fix here but I want to make sure we are looking at the right thing.

Regards,
Andreas

> this has to be system-power-controller;

I am so sorry for the mess up, I was on the wrong branch which is almost the same as pmOS but a bit older, hence the entire mess up. I'll run a quick diff from pmOS and this patch and fix them accordingly.

> There is still a lot other stuff to fix here but I want to make sure we are looking at the right thing.

Could you please go ahead and mention them as well.

Best Regards,
Mithil

well, that takes time, I wanted to start that on the right thing.

1. make dtbs shows warnings

2. make CHECK_DTBS=y ti/omap/omap4-samsung-espresso7.dtb is too noisy
(probably same for espresso10).

a lot comes from the dtsi files, so you need to ignore a lot, probably
either strip down the new dts to almost nothing besides dtsi includes
to determine the background noise or take a similar device, redirect
output and errors, diff that output with the full devicetree.
I am trying to clean that dtsi warning mess up, linux-next shows a lot
less warnings but that takes time.

One of the warnings that should be fixed:
dts/ti/omap/omap4-samsung-espresso7.dtb: lvds-encoder: compatible:
'oneOf' conditional failed, one must be fixed: ['lvds-encoder'] is too
short 'lvds-encoder' is not one of ['ti,ds90c185', 'ti,ds90c187',
'ti,sn75lvds83'] 'lvds-encoder' is not one of ['ti,ds90cf364a',
'ti,ds90cf384a', 'ti,sn65lvds94'] 'lvds-encoder' is not one of
['thine,thc63lvdm83d'] from schema $id:

Yes indeed, I'll be more careful the next time, again sorry for the 
trouble, I am not used to the process of mailing lists and may have done
some mistakes there as well.

Oh, I was not aware of such tool, ran it and yeah there are a ton of
warnings, where can I ask for assitance if I need it while fixing them.

Ah right, I have to add the encoder (doestek, dtc34lm85am) in bindings and
in vendor, this patchset may grow too big I assume.

probably you did not notice an error in make dtbs and the old
devicetree on the device was still there and was used.

I hope you understood that warnings like this:
arch/arm/boot/dts/ti/omap/omap4-samsung-espresso7.dtb:
/ocp/interconnect@4a000000/segment@0/target-module@4000/cm1@0/clocks/pad_clks_ck@108:
failed to match any schema with compatible: ['ti,gate-clock']

are not the ones you need to fix, so just the diff between old and new.

You can do the binding stuff separately, lvds-encoder/panel should be
trivial, so one patch for vendor prefix if needed and one for the
binding.

I messed up my PowerVR tree with mainline, hence the problems. I've fixed
it now locally.

> are not the ones you need to fix, so just the diff between old and new.

Yeah, I ran the command for espresso and then panda for a comparision.
The diff is what i worked on, but I have some doubts which I'd like to ask

dts/ti/omap/omap4-samsung-espresso7.dtb: /: irled@0: 'anyOf' conditional 
	failed, one must be fixed:
        'reg' is a required property
        'ranges' is a required property
        from schema $id: http://devicetree.org/schemas/root-node.yaml# 

Documentation/devicetree/bindings/leds/irled/gpio-ir-tx.yaml does not say
those properties to be required, is the node placed incorrectly?

/home/mighty/linux/arch/arm/boot/dts/ti/omap/omap4-samsung-espresso7.dtb:
 /: pwm@10: 'anyOf' conditional failed, one must be fixed:
        'reg' is a required property
        'ranges' is a required property
        from schema $id: http://devicetree.org/schemas/root-node.yaml#

Similarly here as well.

/home/mighty/linux/arch/arm/boot/dts/ti/omap/omap4-samsung-espresso7.dtb:
current-sense-shunt: 'io-channel-ranges' does not match any of the 
regexes: 'pinctrl-[0-9]+'
        from schema $id: 
	http://devicetree.org/schemas/iio/afe/current-sense-shunt.yaml#

I tried searching the tree for "io-channel-ranges" which has only one
example - ste-ux500-samsung-janice.dts. In that dts the node is same as
in espresso.

Mithil

Well, anything with @ in the node nade needs reg as a property. So
probably best is led-ir since having reg does not make any sense here
since we are not on a bus with devices having addresses on that bus.

Same issue here, too.

Not documented, so not allowed. There is code using it in kernel, but
that might only come into effect if current-sense-shunt has children
nodes. So drop it and check functionality.
