While the AML-S905X-CC Le Potato has overlays to enable both, I2C AO and I2C B, the AML-A311D-CC currently has I2C AO enabled by default but no overlay for I2C B is available, yet.

I did find the AML-S905X-CC i2c-b.dts, but I don’t know if I can just reuse it for the AML-A311D-CC. Also the commented pins 27/28 and the used ones 26/27 seem off by one.
And pointers welcome.
I am doing this to investigate replacing the Raspberry Pi 3B+ in a pi-top with the AML-A311D-CC. The pi-tobHub v2 does fit nicely and I’ll report back with my findings.
