It's also providing some power consumption improvement, but I have only measured that as less heat, which is quite important when working on thermally constrained devices like smartphones. Please note that this driver's yaml binding is referring to a MMCC clock, so this series does depend on the SDM660 MMCC driver that I have sent separately. The multimedia clock is required only for the Multimedia NoC (mnoc). This patch series has been tested against the following devices: - Sony Xperia XA2 Ultra (SDM630 Nile Discovery) - Sony Xperia 10 (SDM630 Ganges Kirin) - Sony Xperia 10 Plus (SDM636 Ganges Mermaid) Changes in v2: - Added missing qcom,mmcc-sdm660.h dt-binding include in the interconnect/qcom,sdm660.yaml binding, as pointed out by Rob Herring Changes in v3: - Moved the dt-bindings/interconnect/qcom,sdm660.h header to dt-bindings commit.
