For a new driver it rarely matters and I'd advise simply using
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
which is the mainline tree.  Please base either on the previous
release (currently 6.2) or rc1 of the current release (v6.3-rc1)
if doing this.

If you need a feature that has only been applied in the same cycle, or
are building on recent work that has been applied to the iio tree then
for fixes you want:
https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio.git fixes-togreg
for new stuff you want:
https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio.git togreg

The IIO tree routes through Greg KH's char-misc tree so will see the togreg
branch move forwards to be based on that as Greg takes pull requests from me.
Usually this happens once or twice a kernel cycle.  Don't worry too much about
this. If it should affect a patch because some changes crossed I'll generally
fix it up whilst applying whichever gets applied second and ask the
authors to check I didn't make a mistake.
