Hi Tobias,
Previously enabling I2C1 when using a V3s-based SoC had no effect. Set pinmux on PE21 and PE22 to I2C1 function when enabling I2C1 on V3s-based SoCs.
Can you say what this patch is about? Is there any V3s board that has the PMIC connected to I2C1? Please note that this code is only for the SPL, where we only use I2C for the PMIC. Anything in U-Boot proper should be covered by the DT.
I am a bit reluctant to add more to this already nasty part of the code, unless there is a good reason: a defconfig for a board requiring this would be one.
Cheers, Andre
