[PATCH v6 1/4] ARM: dts: qcom: samsung-matisse-common: Add initial common device tree

From: Stefan Hansson
Date: Thu Feb 15 2024 - 13:03:58 EST

According to the dts from the kernel source code released by Samsung,
matissewifi and matisselte only have minor differences in hardware, so
use a shared dtsi to reduce duplicated code. Additionally, this should
make adding support for matisse3g easier should someone want to do that
at a later point.

As such, add a common device tree for all matisse devices by Samsung
based on the matissewifi dts. Support for matisselte will be introduced
in a later patch in this series and will use the common dtsi as well.
