Subject: [PATCH v2 6/6] Documentation: connector: Add slow-charger-loop definition
Date: Wed, 7 Apr 2021 13:07:23 -0700 [thread overview]
Message-ID: <20210407200723.1914388-6-badhri@google.com> (raw)
In-Reply-To: <20210407200723.1914388-1-badhri@google.com>
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.
