"Table 6-14 Fixed Supply PDO - Sink" of "USB Power Delivery Specification Revision 3.0, Version 1.2" provides the different power levels and "6.4.1.3.1.6 Fast Role Swap USB Type-C Current" provides a detailed description of the field. The sink PDO from current source reflects the current source's(i.e. transmitter of the FRS signal) power requirement during fr swap. The current sink (i.e. receiver of the FRS signal), a.k.a new source, should check if it will be able to satisfy the current source's, new sink's, requirement during frswap before enabling the frs signal reception. This property refers to maximum current capability that the current sink can satisfy. During FRS, VBUS voltage is at 5V, as the partners are in implicit contract, hence, the power level is only a function of the current capability. "1" refers to default USB power level as described by "Table 6-14 Fixed Supply PDO - Sink". "2" refers to 1.5A@5V. "3" refers to 3.0A@5V. $ref: /schemas/types.yaml#/definitions/uint32 enum: [1, 2, 3] slow-charger-loop: description: Allows PMIC charger loops which are slow(i.e. cannot meet the 15ms deadline) to still comply to pSnkStby i.e Maximum power that can be consumed by sink while in Sink Standby state as defined in 7.4.2 Sink Electrical Parameters of USB Power Delivery Specification Revision 3.0, Version 1.2.
