| Qualcomm Camera Control Interface (CCI) I2C controller |
| |
| PROPERTIES: |
| |
| - compatible: |
| Usage: required |
| Value type: <string> |
| Definition: must be one of: |
| "qcom,msm8916-cci" |
| "qcom,msm8996-cci" |
| "qcom,sdm845-cci" |
| "qcom,sm8250-cci" |
| |
| - reg |
| Usage: required |
| Value type: <prop-encoded-array> |
| Definition: base address CCI I2C controller and length of memory |
| mapped region. |
| |
| - interrupts: |
| Usage: required |
| Value type: <prop-encoded-array> |
| Definition: specifies the CCI I2C interrupt. 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 and sm8250), 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. |
