The Lenovo Yoga C630 is built on the SDM850 from Qualcomm, but this seem
to be similar enough to the SDM845 that we can reuse the sdm845.dtsi.
Supported by this patch is: keyboard, battery monitoring, UFS storage,
USB host and Bluetooth.

Just curious to know if the idea of booting using ACPI is completely
dropped as it's extremely difficult(because the firmware is so hacked
up and may violate spec, just my opinion) for whatever reasons.
We just made ACPI table version checking more lenient for this platform
and would be good to know if we continue to run ACPI on that or will
abandon and just use DT.

Once [0] is applied, we can boot Mainline using ACPI.

Which patch are you referring to? If you mean the ACPI v5.0 vs v5.1
patch authored by Ard, then yes I know, I instigated it's existence
due to these devices.
DT will *always* be more enabled than ACPI, so it's advised that you
use DT for anything useful. ACPI booting is ideal for things like
installing distros however, since they do not tend to provide DTBs in
their installers.

OK, as along as it gets tested/used in some form, that's fine. I do agree
that DT will be more useful on that platform as it was derived from mobile
based SoC SDM845 rather than solely designed for Laptops and with more
alignment with ACPI spec. The way whole power/clock management is done
with ACPI on this pulls me towards DT ;)
