Hmmmmm, so I was looking at msm8926.dtsi downstream and it seems to
override the msm8226.dtsi modem/mss definition [1]:
1. ext-bhs-reg is dropped
2. vdd_mss-supply is added
This common include seems to cover both apq8026 (matissewifi) and
msm8926 (matisselte).
Do we need to handle this difference?
First time I see such a difference between variants of a single SoC.
Looking at all the overrides in msm8926.dtsi, it seems like they made
quite some rework for the "LTE variant".
Thanks,
Stephan
