[PATCH 1/2] mfd: arizona: Add device tree binding to specify mono outputs

From: Charles Keepax
Date: Fri Dec 11 2015 - 05:29:09 EST


Add device tree bindings to support specifying outputs from the chip as
mono outputs. Whilst we are doing it change the out_mono pdata from a
bool to an int, because Sparse gets upset about using ARRAY_SIZE on
bools.
