From mboxrd@z Thu Jan 1 00:00:00 1970 From: Charles Keepax Subject: [PATCH 1/2] mfd: arizona: Add device tree binding to specify mono outputs Date: Fri, 11 Dec 2015 10:28:22 +0000 Message-ID: <1449829703-600-1-git-send-email-ckeepax@opensource.wolfsonmicro.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: devicetree-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: lee.jones-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org Cc: devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, linux-kernel-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, patches-yzvPICuk2AATkU/dhu1WVueM+bqZidxxQQ4Iyu8u01E@public.gmane.org List-Id: devicetree@vger.kernel.org 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.
