I was trying to enable i2c on my RockPro64, and when looking at the documentation in the overlay directory, it states this:
rockchip (Rockchip)
### Provided overlays:
- i2c7, i2c8, pcie-gen2, spi-spidev, uart4, w1-gpio
### Overlay details:
### i2c7
Activates TWI/I2C bus 7
I2C7 pins (SCL, SDA): GPIO2-B0, GPIO2-A7 GPIO1-C5, GPIO1-C4
### i2c8
Activates TWI/I2C bus 8
I2C8 pins (SCL, SDA): GPIO1-C5, GPIO1-C4
Note that the "GPIO1-C5, GPIO1-C4" from i2c8 is accidentally included on the i2c7 pins line.
I would submit a PR for this change, but ... I'm not sure where this document actually lives, and it's not easy to figure out.
I see that @Igor is listed as the maintainer of the package, but that's not helping me find the source to submit changes.
Also, for clarity, it would be nice to include that i2c8 is the pi-connector, and i2c7 is the Digital Video Port
Happy to submit changes if somebody can point me to the right place.
Thanks
