Could be this change done for all the firmware files at once but later?

Currently all the firmwares using this legacy path.

I'd rather see the patch fixing firmware paths first and then the patch
adding SLPI with the correct path from the day 0 (I feel sorry for
causing pain to PmOS maintainers). Of course both patches can come as a
part of the same series.

Would it make sense as a follow up, I would changed "the whole sdm845" 
to the new paths, so distros maintainers can update paths everywhere 
with 6.19?

[PATCH 2/2] arm64: dts: qcom: sdm845-xiaomi-beryllium: Add placeholders and sort

[Robert Eckelmann via B4 Relay]

From: Robert Eckelmann <longnoserob@gmail.com>

We know these devices are present, most of them are supported by
downstream and close to the mainline kernels.

This is very handy when rebasing the integration tree with the support.

No functional changes.

It may be useful for you to add 'status = "okay"' here, so that the busses
are accessible, and you can poke at the device with e.g. i2c-tools
