We might fix it at some point, so not sure if it is worth documenting in

which implement it correctly?
In the upstream there is only one user qcm6490-idp.dts, and changing
the polarity will be an ABI breaking change, unfortunately.
And all other projects?
It might be a challenging task to check usage of "novatek,nt36672e"
compatible display panels in all other projects. I've asked about it:
* https://chatgpt.com/uc/6ae25571-2ef0-83ea-81e5-2522e70c4a93
The check gives this info:
1. Linux kernel - invalid GPIO polarity in the driver and qcm6490-idp.dts,
2. Android - invalid GPIO polarity in the copied driver and qcm6490-idp.dts,
3. FreeBSD - invalid GPIO polarity in the copied qcm6490-idp.dts, no driver.
Please let me know, if there are other projects to check. To my
understanding the RESET_N polarity cannot be corrected anymore,
and the best option is to clearly document a difference between
the device and its dt-binding documentation.
