I can split this patch series, there are two options for splitting:
Option A:
   1. Initial qcs9100.dtsi, qcs9100-pmics.dtsi, qcs9100-ride.dts renamed 
from sa8775p with existing compatible.

   2. Each subsystem have single patch series to each limited driver 
maintainers.

      - About 15 series need to update related drivers, so each series 
will have 3 patches (bindings, drivers, the compatible names in 
subsystem-related parts of dtsi/dts).

      - About 14 series only need to add qcs9100 compatible in 
bindings., so each series will have 2 patches (bindings, the compatible 
names in subsystem-related parts of dtsi/dts).

Option B:

   1. Each subsystem have single patch series to each limited driver 
maintainers. Each patch series only update bindings, drivers, but no 
compatible names change in dts.

      - About 15 series in total and each series will have 2 patches 
(bindings, drivers).

      - About 14 series only need to add qcs9100 compatible in bindings, 
so each series will have 1 patches (bindings).

   2. Squash current qcs9100.dtsi, qcs9100-pmics.dtsi, qcs9100-ride.dts 
with compatible changed to qcs9100 dt files.

We tend to use Option A.

Welcome to other ideas ideas for splitting the huge numbers of patches 
as well.

Another, each splited series will also have cover letter contain the 
whole story like this cover letter.

Previously, I've been using scripts/get_maintainers.pl to obtain a list 
of recipients and manually removing duplicate email addresses(although I 
noticed you have two different email addresses, so I included both).
I'll follow your advice and use b4 to submit a new version patch series 
to upstream, confident that similar issues won't arise again.
