This is a regression introduced by 1373fefc6243 ("usb: typec: tcpm: Allow slow charging loops to comply to pSnkStby") When Source advertises Rp-default, tcpm would request 500mA when in SINK_DISCOVERY, Type-C spec advises the sink to follow BC1.2 current limits when Rp-default is advertised. [12750.503381] Requesting mux state 1, usb-role 2, orientation 1 [12750.503837] state change SNK_ATTACHED -> SNK_STARTUP [rev3 NONE_AMS] [12751.003891] state change SNK_STARTUP -> SNK_DISCOVERY [12751.003900] Setting voltage/current limit 5000 mV 500 mA This patch restores the behavior where the tcpm would request 0mA when Rp-default is advertised by the source. [ 73.174252] Requesting mux state 1, usb-role 2, orientation 1 [ 73.174749] state change SNK_ATTACHED -> SNK_STARTUP [rev3 NONE_AMS] [ 73.674800] state change SNK_STARTUP -> SNK_DISCOVERY [ 73.674808] Setting voltage/current limit 5000 mV 0 mA During SNK_DISCOVERY, Cap the current limit to PD_P_SNK_STDBY_MW / 5 only for slow_charger_loop case.
