[PATCH 0/2] Implement vbus support for HD3SS3220 port controller

Posted by Krishna Kurapati 4 months, 1 week ago

As per the data sheet of HD3SS3220:

"Upon detecting a UFP device, HD3SS3220 will keep ID pin high if VBUS is
not at VSafe0V. Once VBUS is at VSafe0V, the HD3SS3220 will assert ID pin
low. This is done to enforce Type-C requirement that VBUS must be at
VSafe0V before re-enabling VBUS"

This series implements support to read ID pin state and accordingly enable
VBUS.
