Hardware and software info for preproduction Radxa Zero 2

Maintainer: Yuntian Zhang <yt@radxa.com>

Hardware

Known issues: Zero2/Hardware/Revisions

Software

debos-radxa: PR merged. Official build is now part of regular release.

Armbian: PR submitted which also tracks fip, test build inside

Manjaro: [1]

Manjaro KDE BigScreen: [2]

LibreELEC: WIP

CoreELEC: WIP

mraa: Ported

Device tree testing result:

PWM_B, C, and D will need a kernel patch, currently only work in debos-radxa
HDMI audio requires `alsa-utils` from LibreELEC and then it's working
CSI missing mainline driver
DSI mainline driver is under review: https://lwn.net/ml/linux-kernel/20220107145515.613009-1-narmstrong@baylibre.com/
Fan PWM issue listed above
Power button works in the latest Armbian, but not in debos-radxa
Everything else should work

-v1.0 known issues:
+Known issues: [[Zero2/Hardware/Revisions]]
-* lack of clearance around microSD card slot resulting the card will be blocked for insertion. (Workaround: lift the card corner slightly during insertion, so the card can "sit" on that blocking component when fully inserted)
-* TYPC-C headers are slightly misaligned.
-* PCB mounting hole location is different from Zero, as such a proposed universal case cannot share holes on the USB connector side.
-* USB 3 port may not be recognized by the board. (Manually fixed on sample boards)
-* GPIO pin 16 and 24 are connected on the same bus. 16 will be replaced by SARADC_CH1.
-* GPIO pin 36 is an open drain pin. Works fine for input but need pull up for output.
-* Fan's PWM generator is occupied by VDDCPU_B. Preferably an unused PWM pin should go there. Otherwise <code>gpio-fan</code> will be used in device tree.
