I looked at the sxiccmu and it seems to be set up for H3 in both the dtb and
driver. There is a " sxiccmu1 at simplebus0" in dmesg (attached). What
does the message " sxiccmu_ccu_enable: 0x0000003b" in dmesg mean?
I would like to continue with the sxitwi driver as almost all the bits and
bytes in the driver match the H3 datasheet for TWI. The only exception I see
are two enhanced feature registers that I don't think will make any
difference. The default is for the features to be off.
Can someone point me to code that does iic attach, detach, read and write
that I could use as an example to follow. I can't seem to get my head around
iic(9), setting up the parameters. Copying some existing code is much more
what I can handle.

Hi,
after you've finished what patrick@ wrote about, you might want to take a
look at i/sys/dev/fdt/axp20x.c, it could very well be the simplest driver on
iic-bus in tree, and consequently it does attach to sxitwi* :)
