From: Jorik Jonker <redacted> This adds proper pinmux definitions for i2c0 and i2c1. Although H3 has a third i2c controller, these are not exposed on my boards. If someone actually has a H3 board with an exposed i2c2, they could add the third.

These pinmuxes are the only ones possible for each peripheral. Please drop the _a suffix and the @0 address for both of them. ChenYu
