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"
- 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 and
sdm845), 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.
Example:
cci@a0c000 {
compatible = "qcom,msm8996-cci";
#address-cells = <1>;
#size-cells = <0>;
reg = <0xa0c000 0x1000>;
interrupts = <GIC_SPI 295 IRQ_TYPE_EDGE_RISING>;
clocks = <&mmcc MMSS_MMAGIC_AHB_CLK>,
<&mmcc CAMSS_TOP_AHB_CLK>,
<&mmcc CAMSS_CCI_AHB_CLK>,
<&mmcc CAMSS_CCI_CLK>,
<&mmcc CAMSS_AHB_CLK>;
clock-names = "mmss_mmagic_ahb",
"camss_top_ahb",
"cci_ahb",
"cci",
"camss_ahb";
i2c-bus@0 {
reg = <0>;
clock-frequency = <400000>;
#address-cells = <1>;
#size-cells = <0>;
};
i2c-bus@1 {
reg = <1>;
clock-frequency = <400000>;
#address-cells = <1>;
#size-cells = <0>;
};
};
