This is a note to let you know that I've just added the patch titled
dt-bindings: iio: sx9310: Add various settings as DT properties
to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-next branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will also be merged in the next major kernel release
during the merge window.
If you have any questions about this process, please let me know.

Subject: dt-bindings: iio: sx9310: Add various settings as DT properties
We need to set various bits in the hardware registers for this device to
operate properly depending on how it is installed. Add a handful of DT
properties to configure these things.
