We have a production-level laptop (Lenovo Yoga C630) which is exhibiting
a rather horrific bug.  When I2C HID devices are being scanned for at
boot-time the QCom Geni based I2C (Serial Engine) attempts to use DMA.
When it does, the laptop reboots and the user never sees the OS.

Attempts are being made to debug the reason for the spontaneous reboot.
No luck so far, hence the requirement for this hot-fix.  This workaround
will be removed once we have a viable fix.

This compatible isn't in the 5.3 rc series nor is it in linux-next yet.
Is this "hot-fix" for the next merge window? Or is this compatible
string being generated by firmware somewhere and thus isn't part of the
kernel?

It's on the list and will be in all of the distro v5.3 release kernels.

And why don't the distro kernels simply pick up this patch, too?

I could send it to them and find out.  They are on kernel-freeze now,
on the lead-up to the release date (next month), but I think they're
still taking bug fixes.

Submitted.

Does this mean you plan to have this merged for v5.4?

Only if the machine DTS is expected to land in 5.4. But Stephen said it
is not in liunx-next yet?

It appears to be in arm-soc for-next:

Still not in linux-next. Please ping me or resend this patch once it
hits linux-next.

It seems linux-next is now pulling from the soc.git, rather than
arm-soc.git, but Arnd is still pushing patches to arm-soc.git.

Arnd says that the patch will be in v5.4 and I merged Arnd's tree and
gave it a spin here and this patch makes it boot. So please merge this
