Following properties are available only for PM660A: - qcom,qpnp-ibb-smart-ps-enable: A boolean property which upon set enables smart pulse skip mode for IBB regulator. Otherwise, it is disabled. This property is only applicable to PM660A. - qcom,qpnp-ibb-enable-pfm-mode: A boolean property which enables the IBB to work in pfm mode. - qcom,qpnp-ibb-pfm-peak-curr: The PFM peak current limit settings in mA. Supported values are 150, 200, 250, 300, 350, 400, 450 and 500. This property is required if the qcom,qpnp-ibb-enable-pfm-mode is true. - qcom,qpnp-ibb-pfm-hysteresis: The PFM hysteresis voltage threshold in mV. Supported values are 0, 25 and 50. This property is required if the qcom,qpnp-ibb-enable-pfm-mode is specified. - qcom,qpnp-ibb-overload-blank: A boolean property which upon set enables the IBB overload blanking. - qcom,qpnp-ibb-overload-debounce: The expected overload debounce time (in ms) values are 1, 2, 4 and 8. This property is required only when the qcom,qpnp-ibb-overload-blank is set. - qcom,qpnp-ibb-vreg-ok-debounce: The expected vreg-ok-debounce time (us) values are 4, 8, 16 and 32. This property is required only when the qcom,qpnp-ibb-overload-blank is set. - qcom,qpnp-ibb-slew-rate-config: A boolean property to configure the ibb fast/slow slew rate. Either qcom,qpnp-ibb-fast-slew-rate or qcom,qpnp-ibb-slow-slew-rate has to be specified. Otherwise the qcom,qpnp-ibb-slow-slew-rate takes precedence over the qcom,qpnp-ibb-fast-slew-rate. - qcom,qpnp-ibb-fast-slew-rate: This property is required if the qcom, qpnp-ibb-slew-rate-config property is specified. Supported values (in us) are 100, 200, 500, 1000, 2000, 10000, 12000 and 15000. - qcom,qpnp-ibb-slow-slew-rate: This property is required if the qcom, qpnp-ibb-slew-rate-config property is specified. Supported values (in us) are 100, 200, 500, 1000, 2000, 10000, 12000 and 15000. Example: Example: qcom,pmi8994@3 { qcom,pmi8994@3 { qpnp-labibb-regulator { qpnp-labibb-regulator { Loading
