| PFUZE100 family of regulators |
| |
| Required properties: |
| - compatible: "fsl,pfuze100", "fsl,pfuze200", "fsl,pfuze3000", "fsl,pfuze3001" |
| - reg: I2C slave address |
| |
| Optional properties: |
| - fsl,pfuze-support-disable-sw: Boolean, if present disable all unused switch |
| regulators to save power consumption. Attention, ensure that all important |
| regulators (e.g. DDR ref, DDR supply) has set the "regulator-always-on" |
| property. If not present, the switched regulators are always on and can't be |
| disabled. This binding is a workaround to keep backward compatibility with |
| old dtb's which rely on the fact that the switched regulators are always on |
| and don't mark them explicit as "regulator-always-on". |
| - fsl,pmic-stby-poweroff: if present, configure the PMIC to shutdown all |
| power rails when PMIC_STBY_REQ line is asserted during the power off sequence. |
| Use this option if the SoC should be powered off by external power |
| management IC (PMIC) on PMIC_STBY_REQ signal. |
| As opposite to PMIC_STBY_REQ boards can implement PMIC_ON_REQ signal. |
| |
| Required child node: |
| - regulators: This is the list of child nodes that specify the regulator |
| initialization data for defined regulators. Please refer to below doc |
| Documentation/devicetree/bindings/regulator/regulator.txt. |
| |
| The valid names for regulators are: |
| --PFUZE100 |
| sw1ab,sw1c,sw2,sw3a,sw3b,sw4,swbst,vsnvs,vrefddr,vgen1~vgen6 |
| --PFUZE200 |
| sw1ab,sw2,sw3a,sw3b,swbst,vsnvs,vrefddr,vgen1~vgen6,coin |
| --PFUZE3000 |
| sw1a,sw1b,sw2,sw3,swbst,vsnvs,vrefddr,vldo1,vldo2,vccsd,v33,vldo3,vldo4 |
| --PFUZE3001 |
| sw1,sw2,sw3,vsnvs,vldo1,vldo2,vccsd,v33,vldo3,vldo4 |
| |
| Each regulator is defined using the standard binding for regulators. |
