Hi,

Thank you for this!

Tested - one thing that end users/distro packagers may need to be aware
of, if the module is loaded in an initramfs, the firmware file also
needs to be loaded in the initramfs.  If the module is in an initramfs
and the firmware is not, the module will need to be removed and
re-inserted for the device to come up.

Just a heads-up, this reserved memory region shuffling in sdm845.dtsi
broke PocoF1 and may be other devices too(?) which do not override
these regions.

IIRC you once had a patch to move the reserved memory regions to board
specific dts files, is it still on the cards so that we don't run into
breakages like this?

Meanwhile I'll go and add these regions in sdm845-xiaomi-beryllium.dts.

Amit Pundir

As you might remember the feedback I got was to not move the regions to
the individual devices and it was better to just deal with the problem
this way...

But apparently I was too optimistic and should have played the usual
game of deleting the inherited nodes and made the changes in the yoga
dts...

Let's prepare a fix that moves this change into the yoga.dts and get
that landed asap.
