Sending it upstream could enable to fully upstream the u-boot port. The patch adding the DTS has a signed-off-by. The DTS needs to be cleaned up, the reference to non-upstream drivers (like the LCD panel) removed, and sent upstream.Patches only relevant to PinePhone should be sent to pine64. Patches relevant to all A64 devices should be directly sent to sunxi-next. They is a fork of Linux's sunxi-next through MoeIcenowy, downstream projects such as UBports and postmarketOs gather efforts there for future upstreaming.Д¬urrent Linux upstreaming path looks like this: pine64 -> sunxi-next -> linux-next -> torvalds.* Use case: receive signal from modem to wake-up device 17. * Allows deep power-saving modes and later wake-up. * The proprietary firmware can be replaced with Crust 16. Sensors accelerator, gyro, proximity, compass, barometer, ambient light 1 * There's an optional non-free firmware for the auto-focus 18. Single OmniVision OV6540, 5MP, 1/4вЂі, LED Flash 1 * Check if it meets Android 9 requirements

* Serial console is only available in the headphone connector (activated by the 6th contact on the dipswitch 10) * Check if it really requires that firmware or if it has some ROM code that could be used? * Requires a nonfree loadable firmware 3. * The range is too poor to be usable due to the antenna design 22 * Its NMEA protocol variant is already supported by GNU/Linux's gpsd 21 * AT support commands look unusable 20, so we need to use QMI which is way more robust anyway. * PCM audio still experimental: sending to the modem works fine, receiving produces mangled samples 14. * Audio connected to both PCM interfaces on the A64 14. * USB connection for data and I2S connection for audio 18. * The EG-25G is an international version of the EC25. Quectel EG-25G 1 with 2 worldwide bands 4 * Regularly check kernel and Mesa status. * The bootloader should be fully free software 7 including ARM Trusted Firmware 8. The prototype version of PinePhone is already in the hands of developers and a new batch is shipping in January 2020 12, hardware won't change much from now on.
