Thanks for your patch!
According to the DA7212 documentation, it supports 3.4 MHz, too.
But given the I2C bus is also exposed on PMOD, GPIO, and M2 connectors,
1 MHz is probably the safer value.
Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be>
i.e. will queue in renesas-devel for v7.4.
Gr{oetje,eeting}s,
Geert
