ARM: dts: turris-omnia: Add mcu node
PATCH 1/1 ARM: dts: turris-omnia: Add mcu node
At i2c address 0x2a is MCU command interface which provides access to GPIOs connected to Turris Omnia MCU. So define mcu node in Turris Omnia DTS file.
---
Same change was already sent to U-Boot project together with driver. As Turris Omnia DTS file is shared between Linux kernel U-Boot, I'm sending this change also in Linux. There is a plan to write also Linux driver for Turris Omnia MCU, like there is already in U-Boot.

I'm also not sure what the DT people will say about the node name mcu. I don't see any examples of that in the binding documentation. They might request you rename it to gpio-controller, unless it does more than GPIO? And if it does do more than GPIO we are then into mfd territory, and the binding then becomes much more interesting.

Most probably mfd territory. It is at least a gpio-controller, reset-controller and watchdog.

O.K.
Then i suggest we wait for the actual drivers before committing any DT. The binding will need revier, and could change.

I'm not going to send any new yaml dt binding document as I see that dt bindings is clearly deprecated project. Either patches for dt bindings are waiting without any answer for months (maybe year?) or patches are ignored/not accepted by beyond reasons or there are request for changes which cannot work on the real hardware or that new yaml cannot be parsed/validated due to ton of bugs in other schemas.
Sorry, this is just a waste of time and energy to write new those yamls as it does not bring any value.

Yes, there is already driver. See my previous email, I mentioned it and also I wrote link for this driver. Moreover now driver is merged in upstream u-boot.
Driver has currently implemented only GPIO support, but other functions supported by MCU would be implemented later.

I'm not comfortable accepting a DT binding for a driver which does not exist in Linux. As i said, there are interesting ABI issues here, and it could be the MFD, GPIO or reset Maintainers don't accept a binding until a Linux driver exists.
At minimum, you need an Acked-by from the GPIO Maintainer, of the binding before this DT change is merged via MVEBU.

Pali, you wrote in the past that you cannot run one command to install dtschema ("pip") thus for you this automated testing is difficult/broken/non working. If running one "pip" command is not possible, what I can say more? Shall I login to your machine and set it up? Or did you configure your machine that way, that it is not possible to run one pip command?
Whether the patches are waiting for months and years is difficult to address to, without actual links. Because for sure you will be able to find one patch which was missed in our inboxes and you did not get an answer... With Rob we both work much more than reasonable/healthy 8h per day... Yet I recall you always received feedback, just not always what you expected or wanted.

It brings quite nice value - allows to check whether your bindings and your DTS are correct. Any difficulty to install and run dtschema is not equal to "does not bring any value"...
Anyway devices cannot go without bindings, thus it's a NAK.

It brings quite nice value - allows to check whether your bindings and your DTS are correct. Any difficulty to install and run dtschema is not equal to "does not bring any value"...
It just took lot of my time and did nothing useful. Hence for it it has zero value.
Sorry to hear. When I was very, very small, C also took a lot of my time and did nothing useful. Nothing useful in that stage of my knowledge, of course.
Best regards,
Krzysztof

Same change was already sent to U-Boot project together with driver. As Turris Omnia DTS file is shared between Linux kernel U-Boot, I'm sending this change also in Linux. There is a plan to write also Linux driver for Turris Omnia MCU, like there is already in U-Boot.https://source.denx.de/u-boot/u-boot/-/commit/832738974806e6264a3d0ac2aaa92d0f662fd128

I'm not going to send any new yaml dt binding document as I see that dt bindings is clearly deprecated project. Either patches for dt bindings are waiting without any answer for months (maybe year?) or patches are ignored/not accepted by beyond reasons or there are request for changes which cannot work on the real hardware or that new yaml cannot be parsed/validated due to ton of bugs in other schemas.

These are some pretty hard statements that are not nearly true, maybe they are based upon your past experience, but Rob and Krysztof provide feedback within a few days at most on DT bindings and DTS files.

Pali, you wrote in the past that you cannot run one command to install dtschema ("pip") thus for you this automated testing is difficult/broken/non working. If running one "pip" command is not possible, what I can say more? Shall I login to your machine and set it up? Or did you configure your machine that way, that it is not possible to run one pip command?
Sorry no, it is too late. I have already lost interested in it. For me it is like a ride on the dead horse.

Whether the patches are waiting for months and years is difficult to address to, without actual links. Because for sure you will be able to find one patch which was missed in our inboxes and you did not get an answer... With Rob we both work much more than reasonable/healthy 8h per day... Yet I recall you always received feedback, just not always what you expected or wanted.

Now I have replied to one example email without a reaction.
Which was not a patch. You asked us for some knowledge and Rob provided you answers. Or maybe you think that our job is to solve each technical problem of everyone in the world till asking person is happy? Sounds like nice job. :)
No and no. You were unhappy with my last patches, so this time I first send an email asking how to do it prevent sending something which would be rejected. And now you are saying that it is a technical problem, not answer. Nice way how to demotivate to try to do any new contribution into this project area.

Another
example is this https://github.com/devicetree-org/dt-schema/pull/64
which completely blocked any improvements which I proposed in PCIe core code for fixing PCIe state machine. After half of year of waiting I decided to stop any work on this as I see it is dead those schemas.It finished with Rob comments, so ball is on your side, isn't it?
Yes, after half o year? And I should continue to wait another half year for another round? Why? And why should I wait again? Demotivate?

Other examples are that received feedback suggest to do change which does not work on the real hardware. So yes, I cannot accept, expect or want something like that. Schema which works in that ultra-supper-duper software but DTS written according to it does not work on the real hardware is for me useless...

Seems that you just want to demotivate, nothing more.
