Hi Jernej,

The OrangePi Zero 2 is a development board with the new H616 SoC. It
comes with the following features:
  - Four ARM Cortex-A53 cores, Mali-G31 MP2 GPU
  - 512MiB/1GiB DDR3 DRAM
  - AXP305 PMIC
  - Raspberry-Pi-1 compatible GPIO header
  - extra 13 pin expansion header, exposing pins for 2x USB 2.0 ports
  - 1 USB 2.0 host port
  - 1 USB 2.0 type C port (power supply + OTG)
  - MicroSD slot
  - on-board 2MiB bootable SPI NOR flash
  - 1Gbps Ethernet port (via RTL8211F PHY)
  - micro-HDMI port
  - unsupported Allwinner WiFi/BT chip

For more details see: https://linux-sunxi.org/Orange_Pi_Zero_2  
Please no external links.
Shame. I understand the reasons behind that, but this source is rather
stable (more so than some LKML archives ;-), and I copied the actual
important information. But well, I guess people have to put it in their
search engine and hope it doesn't drop them to the vendor's website ;-)

Mmh, but why? I wrote this in 2020, and it was published the first time
that year[1]. If the copyright year means anything, by my understanding
it should cover the earliest publication date, to establish the license
conditions over every copy out there.

As discussed in the past, this will cause reboot issues because Linux will 
turn down above regulator and thus SD card will stop working. This should be 
always on.

And please add pio regulators, this is something we always add later...
Sure, thanks for the heads up, will do.

Cheers,
Andre

Best regards,
Jernej
