| * qpnp-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. |
| |
| Required properties : |
| - reg : The address and size of the peripheral. Size should be 0x1000, and the |
| address may vary. |
| - qcom,cxo-freq : The frequency of the cxo clock in Hz. |
| |
| Optional properties : |
| - qcom,cxo-div : Integer to divide the CXO clock by when constructing the |
| output frequency. Please see the definitions in |
| include/linux/qpnp-clkdiv.h to choose the appropriate value. |
| - qcom,enable : 0 == disable clock output |
| 1 == enable clock output. |
| |
| Note: if an optional property is not specified, no device configuration will |
| occur at probe time. |
| |
| Client required properties : |
| - <consumer name>-clk : A phandle to the corresponding divclk device. The |
| consumer name refers to the name that will be |
| passed to qpnp_clkdiv_get(), and allows for a |
| client specific name to be associated with each |
| divclk. |
| |
| Clkdiv device example : |
| |
| ... |
| pm8941_clkdiv1: clkdiv@5b00 { |
| reg = <0x5b00 0x1000>; |
| qcom,cxo-freq = <19200000>; |
| qcom,cxo-div = <1>; |
| qcom,enable = <1>; |
| }; |
| |
| Client device example : |
| ... |
| client { |
| my-clk = &pm8941_clkdiv1; |
| }; |
