Thanks for applying the patch.

I left those out deliberately for now until I could reboot the
machine to perform some tests with the watchdog settings in the BIOS.
I wasn't sure about them, because these registers aren't mentioned in
the tables on page 68 .. 71 of the datasheet, but they are mentioned
further down. They also aren't in the F71882FG/F71883FG version.

Your additions look good to me. Maybe the default for VID register 0xf2
can be changed to 0x00?
What about the very similar F71882FG/F71883FG?

I missed that one.

You changed the default value of register 0x27 from 0x30 to MISC.
I had chosen the not pulled-down setting as the default.
Whatever default you decide to use, you should probably also change
that for the F71882FG/F71883FG.

You also changed the default value of UART2 register 0xf1
from 0x00 to 0x04. My datasheet does mention 0x04. Do you have a
different datasheet?
