"Table 6-14 Fixed Supply PDO - Sink" 198 of "USB Power Delivery Specification Revision 3.0, Version 1.2" provides the 199 different power levels and "6.4.1.3.1.6 Fast Role Swap USB Type-C Current" 200 provides a detailed description of the field. The sink PDO from current source 201 reflects the current source's(i.e. transmitter of the FRS signal) power 202 requirement during fr swap. The current sink (i.e. receiver of the FRS signal), 203 a.k.a new source, should check if it will be able to satisfy the current source's, 204 new sink's, requirement during frswap before enabling the frs signal reception. 205 This property refers to maximum current capability that the current sink can 206 satisfy. During FRS, VBUS voltage is at 5V, as the partners are in implicit 207 contract, hence, the power level is only a function of the current capability. 208 "1" refers to default USB power level as described by "Table 6-14 Fixed Supply PDO - Sink". 209 "2" refers to 1.5A@5V. 210 "3" refers to 3.0A@5V. 211 $ref: /schemas/types.yaml#/definitions/uint32 212 enum: [1, 2, 3] 213 214 slow-charger-loop: 215 description: Allows PMIC charger loops which are slow(i.e. cannot meet the 15ms deadline) to 216 still comply to pSnkStby i.e Maximum power that can be consumed by sink while in Sink Standby 217 state as defined in 7.4.2 Sink Electrical Parameters of USB Power Delivery Specification 218 Revision 3.0, Version 1.2.
