The format of the specifier is defined by the binding document describing the node's interrupt parent. - clocks: Usage: required Value type: <prop-encoded-array> Definition: a list of phandle, should contain an entry for each entries in clock-names. - clock-names Usage: required Value type: <string> Definition: a list of clock names, must include "cci" clock. - power-domains Usage: required for "qcom,msm8996-cci" Value type: <prop-encoded-array> Definition: SUBNODES: The CCI provides I2C masters for one (msm8916) or two i2c busses (msm8996, sdm845, sm8250 and sm8450), described as subdevices named "i2c-bus@0" and "i2c-bus@1". PROPERTIES: - reg: Usage: required Value type: <u32> Definition: Index of the CCI bus/master - clock-frequency: Usage: optional Value type: <u32> Definition: Desired I2C bus clock frequency in Hz, defaults to 100 kHz if omitted.
