| 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. |

| state as defined in 7.4.2 Sink Electrical Parameters of USB Power Delivery Specification |
| Revision 3.0, Version 1.2. When the property is set, the port requests pSnkStby(2.5W - |
| 5V@500mA) upon entering SNK_DISCOVERY(instead of 3A or the 1.5A, Rp current advertised, during |
| SNK_DISCOVERY) and the actual currrent limit after reception of PS_Ready for PD link or during |
| SNK_READY for non-pd link. |
