Hi Denis,
I have high interest in this target device and wanted to provide some
assistance if that's ok with you.
I've fixed most of the open stuff, with the exception of using a PCIe
device in the slot. (checking currently what is wrong there)
Changes:
- dts cleanup
- Enabled USB
- Added required GPIO's for USB switching functionality (Type-A vs mini
pcie slot)
- Added pcie device power gpio (default ON)
- Added kernel 5.10 support
- use maximum SPI speed compatible with any type/brand of EEPROM (Dual &
Quad)
- use maximum SPI speed compatbile with any type/brand of SSR chip
- added beeper package
I also have different hw revisions of this board.
- Oldest revision: works as expected, also when booting from flash
- Newer revision: ethernet works when booting from ethernet, but not
when booted from flash (interface is up, IP is set, but not able to ping
it.)
I also have a board running latest RouterOS on it.
It seems it should be possible to also fetch Voltage and Temperature
somewhere.
Do you have an update?
Thanks,
Kind regards,
Koen

interesting. I have a rb92xx on my desk and am wondering if this would
also work ? after a brief glance at the code I think this might work.
the rb92xx certainly has the same latch setup ...

When porting RB91xG ad hoc drivers (gpio-latch and rb91x-nand) from
ar71xx
to ath79, I made a decision to rework this to more clear design in my
opinion:
MFD driver that requests and controls the gpio lines, and separate NAND
driver and GPIO-latch driver that uses API of the MFD driver (like
how in rb4xx-clpd is done). ar71xx gpio-latch is very good, but
somewhat hacky,
so I don't think that it can be general driver for gpio controller on
a latch.
I could be wrong. Also it is my first attempt to port OpenWrt to a
device, so
I need a review from the community. I've tested all these on my
RB912UAG-2HPnD.
Gigabit Ethernet, 2.4GHz Wi-Fi, sysupgrade and LEDs:) are working for
me.
Not working: beeper, button and USB port/mPCIe (has not tested yet).

ath79: add MFD driver (NAND and GPIO) for Mikrotik RB91xG
ath79: add GPIO-latch driver for Mikrotik RB91xG
ath79: add NAND driver for Mikrotik RB91xG
ath79: add support of Mikrotik RouterBoard 91xG series
