Hi Rob,
Have clarified "slow charger loops" and pSnkStby in my V3 of the patch
and have updated the subject as well.
I was actually doing a git log where the last one showed up with the
following commit description.
commit 4b59b60d896f3ed94921974e916db091bc3a9ba8
Author: Kyle Tso <kyletso@google.com>
Date: Fri Feb 12 15:37:43 2021 +0800
Documentation: connector: Update the description of sink-vdos
Remove the acronym "VDM" and replace it with the full name "Vendor
Defined Message".

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.
