Serial port (in the headphone jack)	Upstream	Subject to hardware issues [1] Extra patches: 7fe2f541f9336 arm64: dts: sun50i-a64: Set fifo-size for uarts[2] da34508bae5de tty: serial: 8250-dw: Use fifo-size from DTS[3] Both patches go together, and appear to be a performance optimization only.
Display	Partial	doesn't run at 60hZ (TODO: add link to megi's patches)
Touch Input	untested
Fromt camera	in progress	Front camera driver should be upstream in 6.8-rc1, but will need testing and dts parts to activate[4]. (TODO: track them down links to source & lkml threads)
Rear camera	untested	driver should be upsream
Wifi	in progress[5]	The current driver has very poor code quality and will not be suitable for mainline. Work on a replacement is in progress.

Feature	status	notes
Role Switch / Gadget mode	out of tree	See #ANX7688
Host mode e.g. external storage or input	Partial	It appears that usb devices don't get power from the phone. They only work when plugged into the dock with external power.
DisplayPort alt mode	out of tree	See #ANX7688
USB-C Power Delivery	out of tree	See #ANX7688
USB BC	Upstream	BC1.2 is mostly handled by the axp803 pmic. This is usually what handles current negotiation when using A-to-C cables and dumb chargers.

ANX7688

There is an out of tree driver for the anx7688 chip, but it was written specifically for the PinePhone. This driver may require non trivial refactoring to be acceptable upstream.
