- Qualcomm Technologies, Inc. QPNP clock divider (clkdiv)
- clkdiv configures the clock frequency of a set of outputs on the PMIC.
- These clocks are typically wired through alternate functions on
- gpio pins.
- =======================
- Supported Properties
- =======================
- - compatible
- Usage: required
- Value type: <string>
- Definition: should be "qcom,qpnp-clkdiv".
- - reg
- Usage: required
- Value type: <prop-encoded-array>
- Definition: Addresses and sizes for the memory of this CLKDIV
- peripheral.
- - qcom,cxo-freq
- Usage: required
- Value type: <u32>
- Definition: The frequency of the crystal oscillator (CXO) clock in Hz.
- - qcom,clkdiv-id
- Usage: required
- Value type: <u32>
- Definition: Integer value specifies the hardware identifier of this
- CLKDIV peripheral.
- - qcom,clkdiv-init-freq
- Usage: optional
- Value type: <u32>
- Definition: Initial output frequency in Hz to configure for the CLKDIV
- peripheral. The initial frequency value should be less than
- or equal to CXO clock frequency and greater than or equal to
- CXO_freq/64.
- =======
- Example
- =======
- qcom,clkdiv@5b00 {
- compatible = "qcom,qpnp-clkdiv";
- reg = <0x5b00 0x100>;
- qcom,cxo-freq = <19200000>;
- qcom,clkdiv-id = <1>;
- qcom,clkdiv-init-freq = <9600000>;
- };
