[PATCH v1 6/6] Documentation: connector: Add slow-charger-loop definition

From: Badhri Jagan Sridharan
Date: Mon Apr 05 2021 - 21:37:17 EST


To allow slow charger loops to comply to pSnkStby requirement,
this patch introduces slow-charger-loop which when set makes
the port request PD_P_SNK_STDBY_MW upon entering SNK_DISCOVERY
(instead of 3A or the 1.5A during SNK_DISCOVERY) and the actual
currrent limit after RX of PD_CTRL_PSRDY for PD link or during
SNK_READY for non-pd link.
