Subject: [PATCH v3 1/3] arm64: dts: qcom: sm8750: Add Iris VPU v3.5
From: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
Add Iris video codec to SM8750 SoC, which comes with significantly
different powering up sequence than previous SM8650, thus different
clocks and resets. For consistency keep existing clock and clock-names
naming, so the list shares common part.
