From f199d39349beabcb1a374cb02e0845a0ae84f3fd Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Mon, 14 Dec 2015 10:19:11 +0000 Subject: [PATCH] mfd: arizona: Add device tree binding to specify mono outputs 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.
