[gregkh]

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

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).
