Date: Mon, 18 Sep 2017 15:46:46 +0200 From: Geert Uytterhoeven <geert+renesas@...der.be> To: Daniel Lezcano <daniel.lezcano@...aro.org>, Thomas Gleixner <tglx@...utronix.de>, Rob Herring <robh+dt@...nel.org>, Mark Rutland <mark.rutland@....com>, Magnus Damm <damm+renesas@...nsource.se> Cc: Laurent Pinchart <laurent.pinchart@...asonboard.com>, devicetree@...r.kernel.org, linux-renesas-soc@...r.kernel.org, linux-kernel@...r.kernel.org, Geert Uytterhoeven <geert+renesas@...der.be> Subject: [PATCH v3 6/7] clocksource: sh_cmt: Remove unused "renesas,channels-mask" handling The in-driver channel configuration in sh_cmt_info.channels_mask is now always set for all CMT devices instantiated from DT. Hence the "renesas,channels-mask" property is no longer checked, and its handling can be removed, cfr. commit 4e18111ff38f0664 ("devicetree: bindings: Remove deprecated properties").
