usb: typec: tps6598x: Export some power supply properties

This allows downstream supplies and userspace to detect whether external power is supplied. The Librem 5 has the tp65982 in front of bq25980 charge controller. Since that is capable of sinking and sourcing power the online property helps to decide what to do. It also makes upower happy. There will be follow up patches providing more properties but these need some more time to cook and i wanted to check if this is the right way to go? changes from v1 - As per review comments from Heikki Krogerus https://lore.kernel.org/linux-usb/20201126123552.GP1008337@kuha.fi.intel.com/ - select POWER_SUPPLY - use POWER_SUPPLY_USB_TYPE_PD when a PD contract got negotiated Guido Günther (1): usb: typec: tps6598x: Export some power supply properties drivers/usb/typec/Kconfig | 1 + drivers/usb/typec/tps6598x.c | 105 +++++++++++++++++++++++++++++++++++ 2 files changed, 106 insertions(+)
