I don't know if it's a subset of all boards. There are enough TQMa6ul device trees already, I don't think we should keep even more of them around. > > + writel(0x12, iomux + 0x0094); > > + writel(0x0, iomux + 0x05bc); > > + writel(0x1b8b0, iomux + 0x0320); > > + writel(0x12, iomux + 0x0098); > > + writel(0x0, iomux + 0x05c0); > > + writel(0x1b8b0, iomux + 0x0324); > > Could iomux_v3_setup_pad and pinctrl macros be used here instead?

I though we have to select I2C to get I2C_IMX_EARLY, but apparently that's not necessary.
