[RFC v3 09/11] arm64: dts: mt7986: add Bananapi R3

Frank Wunderlich
2022-11-06T08:51:13Z

From: Frank Wunderlich <frank-w@public-files.de>

Add support for Bananapi R3 SBC.

- SD/eMMC support (switching first 4 bits of data-bus with sw6/D)
- all rj45 ports and both SFP working (eth1/lan4)
- all USB-Ports + SIM-Slot tested
- i2c and all uarts tested
- wifi tested (with eeprom calibration data)

Signed-off-by: Frank Wunderlich <frank-w@public-files.de>

SPI-NAND/NOR switched (CS by sw5/C) not yet included
this is done with DT-Overlays in my tree, don't know how to do it
in upstream the right way...added dts files for dtbo and added them
with dtbo extension to Makefile works.

changes:
v3:
- rename factory-key to reset-key
- add dcin regulator and add it as input for 3v3 (with renaming)
- remove memory-node
- dropped wifi eeprom (calibration) data
- move mmc0 pinctrl to common dtsi and drop sdcard comment
- change mmc pull-up/down to have generic bias-pull*

v2:
- remove pcie to be added later (discussion about clocks)
- some fixes based on suggestions on ML
- add key suffix like it's done in mt7622-bpi-r64 devicetree
- add dash in sfp node names
- use reg as unit for switch-node
- drop "-3-4" suffix from i2c-pins node name
- fix order in Makefile
