If this device has UFS 3.x flash, which it most likely does, the
copy-pasted eLDO comment does not apply.. and VCC range is 2.4V-2.7V,
2.95 is overvoltage!
If it's actually UFS 2 after all, it would be better to rename the
property to vccq2-supply.

Hello Val,
Thank you for the review.
Though you're right that this comment is a copy-paste, taoyao has ufs2.
This is the explaining comment from the downstream sources:

So I thought it's better to keep a small comment regarding eLDO.

Could you elaborate please? Do you mean l9b?

That's a comment from the qcom reference sources! I've literally seen it
already in the downstream DTS for the device I'm currently working on
(motorola-dubai) which definitely has UFS 3, hehe.
You can read
/sys/bus/platform/devices/1d84000.ufshc/device_descriptor/specification_version
to see which UFS spec version your flash is (0x310 == 3.1 etc.)
(Lots of interesting stuff around there, there's also health_descriptor
that shows your flash's wear estimation..)
Also if you have the schematics, you can check for whether an LDO is
actually present there and whether VCCQ or VCCQ2 is connected :)

No, the "vccq-supply". If you look at
Documentation/devicetree/bindings/ufs/ufs-common.yaml you can see it
supports both `vccq-supply` and `vccq2-supply`, the former is used for
UFS3 and the latter for UFS2.
Thanks,

Unfortunately, I wasn't able to find schematics. It also a bummer that I
don't know panel's name because I have a (semi-generated) driver for it.

Will fix it in v5. Thanks a lot for so many inputs!
