[PATCH v2 4/4] arm64: dts: qcom: sm8650: add description of CCI controllers

Vladimir Zapolskiy
2024-06-12T21:58:44Z

Qualcomm SM8650 SoC has three CCI controllers with two I2C busses
connected to each of them.

The CCI controllers on SM8650 are compatible with the ones found on
many other older generations of Qualcomm SoCs.
