[RFC PATCH] dt-bindings: PCI: ti,j721e-pci-host: Add device-id for TI's J784S4 SoC

[Siddharth Vadapalli]

Add the device-id of 0xb012 for the PCIe controller on the J784S4 SoC as
described in the CTRL_MMR_PCI_DEVICE_ID register's PCI_DEVICE_ID_DEVICE_ID
field. The Register descriptions and the Technical Reference Manual for
J784S4 SoC can be found at: https://www.ti.com/lit/zip/spruj52

Why is this patch incomplete? What is missing here? What are you asking
about as RFC?

Best regards,
Krzysztof

Since the merge window is closed, I was hoping to get the patch reviewed in
order to get any "Reviewed-by" tags if possible. That way, I will be able to
post it again as v1 along with the tags when the merge window opens. For that
reason, I have marked it as an RFC patch. Is there an alternative to this "RFC
patch" method that I have followed? Please let me know.

This is v1, so that would be v2.

Then how does it differ from posting without RFC? Sorry, RFC is
incomplete work. Often ignored during review.

Krzysztof

I was under the impression that posting patches when the merge window is closed
will be met with a "post your patch later when the merge window is open"
response. That is why I chose the "RFC patch" path since RFCs can be posted anytime.

For the Networking Subsystem, it is documented that patches with new features
shouldn't be posted when the merge window is closed. I have mostly posted
patches for the Networking Subsystem and am not sure about the rules for the
device-tree bindings and PCI Subsystems. To be on the safe side I posted this
patch as an RFC patch.

Thank you for clarifying that it is alright to post patches even when merge
window is closed. Going forward I shall not post RFC patches unless it really
requires feedback and suggestions.

Ah, so you want to go around that policy by posting non-RFC patch as
RFC. It does not work like that.

Krzysztof

Thank you for clarifying. May I post the v2 of this patch in that case, after
rebasing it on the latest linux-next? I wish to receive feedback or Reviewed-by
tags for the v2 patch and post the v3 accordingly when the merge window opens again.
