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-testing 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 be merged to the staging-next branch sometime soon,
after it passes testing, and the merge window is open.

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.
