This is a note to let you know that I've just added the patch titled
dt-bindings: iio: ad7192: Add mandatory reference voltage source
to my char-misc git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git
in the char-misc-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: ad7192: Add mandatory reference voltage source
Add required reference voltage (VRef) supply regulator.
AD7192 requires three independent voltage sources: DVdd, AVdd and VRef
(on REFINx pin pairs).
Fixes: b581f748cce0 ("staging: iio: adc: ad7192: move out of staging")
